BEFORE YOU COMMENT: Please know my stance about emulating the quirks and flaws of original hardware. In short, I LOVE HOW THE HARDWARE ORIGINALLY SOUNDS. That's it. If I never made this experiment, I would have been recording audio straight from various hardware and saving them for my collection. I firmly believe that every hardware is unique and its individual quirks should be perfectly preserved via proper emulation, or better, lossless hardware recordings. Even if the Namco N163 sounds like crap, it's what it is, and it should sound like that. Now, for the people who say, "[the stuff I tried to do in this video] doesn't make it better". You know what? "Better" depends on the goal of the individual. If you're trying to say that "smoothing out the triangle wave doesn't make it better", then in the perspective of recreating the sound of the original hardware, of course that's bad. But for the purposes of THIS VIDEO, whose goal is to make an experiment and hear how the NES *could* sound like if its flaws were not present, then it doesn't matter. The NES is trying to make a triangle wave. However, a triangle wave does not have steps. I merely helped the NES achieve what it was trying to achieve. And the result was interesting to hear, so I shared my findings. I never claimed that "the NES should sound like this" or anything similar. If anything, I learned to appreciated the NES more-by fixing its flaws, I understood just how many sacrifices it had to make to even generate the sounds it can generate. Again, for the last time, I fully support the faithful recreation of hardware audio. I hope you understand. Feel free to continue writing your comment even if it is "you killed the NES and it will come to haunt your dreams". However, if that is the case, as writing and explaining the same thing over and over again is tiring, and there are other comments on different topics that could spark a more interesting conversation, I may not be able to reply to your comment. Please understand.

You killed the NES and it will come to haunt your dreams! In all seriousness that was extremely fascinating, even if I didn't understand a good portion of it, haha. I absolutely love the NES and things like the VRC6 Chip I only discovered about a week ago and I was floored that the NES could output even something like that. Making the sounds even crisper is a work of art. That's some awesome stuff, really good job! I'd love to hear the Level 1 Theme of the Japanese version of Castlevania 3 with the crisper sound, that track slaps. I hadn't seen your channel until today but I'm definitely going to keep an eye on it in the future!

Your effort and ones like it don't take away from the efforts to accurately emulate the original hardware. Everyone gets the best of both worlds. I don't know why people get so angry about it.

The jagged triangle wave was a product of limitted hardware capability yes, but the added bonus to that is that if the triangle were used as a bassline (which it very often was) those higher harmonics would help it to be more audible on the shoddy speakers most CRT TVs had back then. A straightup triangle would be totally lost on those in the lower registers.

The beauty of these spruced up tracks is the clear and deep bass that sprung out of them - even though I sort of like the original quantisation noise on the FM chip :) I have a Yamaha DX7s which although supposedly much cleaner sounding than the original DX7 is still very noisy .. but not in an annoying way :)

It's one of the few things humans have created from whole cloth, without trying to mimic or improve on nature. My favorite sound is the OPN2, but the OPLL (and VRC7 by extension) is very closely related to it. I've never heard an OPLL as clear and clean as the VRC7 in this video, though. Thanks for this.

I’ve seen a lot of people arguing about how the composers used the inaccuracies with their equipment to their advantage, and something similar happened with plasma screens and old TVs. Lots of sprites from back then look loads better when on the screens they were designed for with the color fuzz and gaps in pixels. In some of the Sonic games they used the TV screen to take a unicolor waterfall sprite and when displayed on a TV, it got these even vertical lines of different shades of blue.

It should be noted that composers of the time tended to be aware of these limitations, and often relied on said quirks to achieve interesting effects: the stepped triangle wave has a shimmering quality to it which can enhance a track's liveliness, or even used to ominous effect in Journey to Silius, where the sounds acquire sort of a sci-fi vibe that is a bit choked out when cleaned. The last track, The Coffee Zone, also benefits greatly from the quantization noise, which makes it sound like there's a drummer playing brushes throughout the song; it speaks more of "jazz band in a seedy bar" to me that way. On another note, this topic reminds me of any debate where technology limitations make anything fuzzier and warmer: vinyl vs CD; CRT vs LCD; valves vs transistors and so on and so forth. There's just an aura of maybe nostalgia to any technology which degrades an otherwise pristine source signal, and stripping them down to their essence to be revealed as generated invariably makes them feel aseptic. You just can't substitute for said "loss in translation", to the extent of actively trying to replicate these flaws that were once perceived as undesirable.

That is the reason I mentioned the valves VS transistors debacle: it is absolutely possible to make great sounding solid state guitar amps nowadays, in fact there is a whole market for them. I like both, personally, because they have different characteristics that work well in their respective genres. And sure, you could build a clone of a vintage Fender amp and swap out any part you'd like, but any change done to its sound signature cannot be considered an improvement, because every element contributes to creating its identity. That's the issue at hand here: this fellow cannot claim to have created the "perfect" NES sound, because that spot is already taken by the original design. As a matter of fact, whenever emulators struggle in recreating a 1:1 sound print of the original systems, it is tendentially because an emulation often fails to recreate the little imperfections which made the original design special (especially egregious with OPL-based sound systems, which are dependent on so many more elements to work their magic).

@@vyor8837 Eehhh... not quite. That's a subjective topic which has been going on ever since transistors were invented, and there is no clear winner there as long as the components are not brought beyond their physical limits; but I will not argue that, because we were making a slightly different point. We were talking about transistors VS valves in the specific application of guitar amplifiers. I mentioned earlier that transistors and amps do not sound that different, as long as the signal passing through them does not exceed their rating, which is normally what you want in a hi-fi or somesuch; but with amps, those specs are routinely stressed, like when you're cranking the gain to intentionally overdrive or distort the signal. When you're saturating valves and transistors in such a way, the sound is getting mangled in both cases, but these components behave very differently: with transistors, the signal usually gets clipped past a certain point, while with valves it breaks down and frays in a different manner, which sounds warmer and less "screechy" than with transistors. Which is a similar thing to what happens on vintage consoles, with their "imperfect" components that alter the sound in a less than ideal, but beautifully iconic way. Change any of that with an audibly different part (for better or for worse), and you've butchered the original sound.

This is actually a modified NSFPlay. Everytime the NES CPU sets the frequency of the triangle wave, I set a counter for how long it takes to complete a whole cycle of the waveform, and based on that an a counter (which has 32-bits precision, meaning a smooth waveform can be generated), a linear interpolation code generates what value should be output at the time. This is exactly how I also approached the VRC6's sawtooth wave. I will be very glad to upload Dr. Willy's Castle (is that the second Dr. Wily stage?) and Fire Emblem.

It's amazing how much creativity and tuning was involved in designing such simple devices. In comparison nowadays everything is poorly optimized and if you complain they just tell you to buy better hardware...

Although some of these fixes were very cool, I find that the NES triangle wave works better with bitcrushing. It just has a much crunchier, agressive sound that I think makes it work exceptionally well as a bass instrument. I would have never been able to think of the bitcrushing as a bad thing. I will admit tho, at high pitches some of the harmonics in the 2A03's triangle can become quite annoying. If there was a way to filter or EQ it while keeping it 4 bit, that would be a dream. The VRC6 saw harmonics CAN be specially annoying since they are very dissonant and audible at regular low pitches; but in a full song, they are always going to be masked by other instruments so it's not that big a deal. Fixing non linear mixing is also good but, and since so many NES soundtracks are well thought around it, it would probably work just in certain ocassions. Idk though, I should probably take a listen to many of your fixed soundtracks to actually tell. Over all, really cool content! I'd love to see more in-depth chiptune analysis like this on KZread.

Hello! Thanks for telling me your thoughts! I actually agree! The NES triangle sounds too quiet without the harmonics, and the harmonics actually help make the bass notes more noticeable. That is the case in most if not all songs. The VRC6 saw, on the other hand, I actually dislike... It is has less bits (3) than the NES triangle wave (4), and it sounds so bad with really audible harmonics... You are right that it gets masked with the other channels in a full song, but it can be heard when the other channels are not playing. I'd really rather have it without its extra harmonics 😅 As for the non-linear mixing, yes, I think that's true. Many programmers will have adjusted volume levels to mix the song better. Still, in a perfect world, channels should mix linearly, so I tried to force linear mixing.

@@KYLXBN about the non-linear mixing: AFAIK, the NES CPU has 2 audio output pins - one for the square wave channels and another one for everything else - so you could do the mixing (well, at least the balance between squarewaves and everything else) externally, bypassing the audio circuits on the NESs mainboard entirely I've read about a mod that does exactly that - it requires lifting those pins and running the signals on separate wires into a mixing + amplification board for cleaner sound and whatnot - but wouldn't mixing it externaly (and thus, not have one channel affect the loudness of the other channels) introduce a risk of messing the mix up? I'd like to try a similar mod because i think it would be interesting to run the square waves through something like a subtle stereo chorus or add a tiny amount of stereo delay to "widen" the sound stage and make it more interesting ... to test this, i ran the regular mono output of the NES through a stereo delay+chorus guitar pedal and found out that it could indeed add to the sound if you dial the pedal in VERY carefully ... and that the harmonics of the triangle wave can become unpleasant very easy if you twist a knob just a bit too far ... so i'd really like to only apply this processing to the square channels - as they are usually used for BGM melody while the other channels are used for SFX, BGM bass and percussion - and i usually want percussions and bass to be tight with no wishy-washy delay effects .. plus, the harmonics problem is another reason NOT to process the triangle channel.

I agree with the OP -- the triangle's harmonics have always been a signature of the NES that I've found interesting from the days of olde, as an audio-obsessed kid, through to today. I think it was a very practical decision, as a way to make an analog waveform with digital switching, but also works really well given its ideal use as a bass instrument on TVs with small speakers. The harmonics allow for a psycho-acoustic effect where you may not hear the fundamental, but you hear the harmonics, and your brain fills in the lower octaves. This will still be present with a smooth triangle (but not with a true sine), just much less so. It can indeed get whistley at higher frequencies, like the latter parts of the Metroid theme, but so be it. I've really never been a fan of the VRC's extra channels. I just find sawtooth waves to be a bit raunchy for my taste. IMO, smoothing out the aliasing didn't help -- it made it sound more like a SID. I had a C64 as a kid as well, and I always felt the SID sounded like a porcupine walking down a hallway carpeted with sandpaper. I'm not a huge FM fan, but I do agree the mixing sounds better on the "fixed" version. I guess my ears just don't agree with quantization noise on more complex waveforms, but simple waveforms benefit from the increased complexity of the overtones. Just my 2c. All in good fun. BTW, I'm not _strictly_ a purist -- I actually really enjoy modified panning, with the square waves panned L and R, and the tri, noise, and PCM down the center. :-)

This feels like the audio equivalent of turning old animations into 60 fps ones with interpolation software. It's interesting to see the end result, but it's also interesting to see how clearly the original animators (or the original sound designers) clearly knew and could take advantage of their limitations. Just like how making an old Disney movie 60 fps might make it seem smoother, but lose some of the original animation's timing, this makes the original games' audio much cleaner, but it loses the original's actual sound. I do prefer the originals, both ways, but this is really cool. And it always makes me wonder what new songs would sound like if they were played on these old sound chips.

It's extremely interesting. A lot of people, myself included, pursue "perfection", when it comes to audio. Whether that be a "cleaner" mix, higher quality samples, or in this case, more smooth and less jagged waveforms. However, everyone's perfect is different, and all of these different sounds are nothing more than sounds, they just exist and have different properties. There are advantages and disadvantages to each, and the goal in music is not to be obsessed with cleanliness and orderliness but rather to take each sound as it is and do what sounds best with it!!!

I agree that the original audio is original but I don't think it's fair to compare this hardware modification to 60 fps AI interpolation, because when making extra frames, the AI is taking lots of mild guesses. While in this experiment here (If I understood correctly) the uploader modified the hardware to take already existing data and output it in another way. Obviously the developers (or should I say the composers) intended for the original audio to sound the way it does on the original hardware, but I doubt that they were always happy about the way they had to make their music sound because of the limitations they had to work with. Whether making the jagged curves and lines smooth sounds better is really subjective, since when they are jagged they give a song this nostalgic charm that old consoles with this limited hardware had. But I think that most of us can agree that relaxing music without the extra noise does sound quite better and well, relaxing. So well, it's up to taste, but I believe that this experiment did make many things sound better.

That's the beauty of those old systems, the things they figured out with limited capabilities. The work-arounds and compromises they made to give new gaming experiences while working with essentially the same hardware made gaming accessible to the masses. An NES or an arcade cabinet had a fraction of the power of our phones but they learned how to get the very most out of it. Today the sky is the limit, but you need a computer that costs thousands of dollars to get the full effect of what the designers have created, and most people aren't able to do that.

Absolute banger of a video, love the revitalized old school sounds. Definitely adding this to my list of great videos. Keep up the amazing work!

When I was a kid I noticed that weird triangle wave sound. A real triangle wave sounds better, but to me, the original one is very different from the square waves (the real triangle just sounds very similar), so it adds complexity to the music.

The thing is, the NES's triangle wave is a very nostalgic sound. It's _distinctly_ NES. As in, when you hear it, it immediately registers as "NES music". That jagged triangle wave is unique to the 2A03 and you could argue that the charm is lost if it's smoothed out.

EE here -- sampling and information being what they are, I'd humbly suggest trying to smooth the corners of the sawtooth, with an exponential curve (or filter), with time constant near the [original] sample rate. The idealized-sawtooth test is extremely grating on the ears; the risetime is -- well, I didn't record it to check, but I'm assuming it's at whatever the upsampled rate is? Which, mind, might be an intentional aspect, just as the steps of the original chip might be used intentionally by composers -- and so, likely plays better in some songs than others. But other methods of filling in that missing information can be tried, and are just as valid. That's the issue here, of course; the low sample rate implies missing information, but there's no way to recover, infer or imply what is actually missing. So it's up to experiments like this, to see what works and where (i.e. for what songs). Likewise, for interpolating PCM, it's hard to say; the aliasing might be intentional -- particularly for noisy samples like cymbals. The best you can do in terms of band-limited filtering is probably sinc interpolation (i.e., brick wall filter at Fs/2). Linear interpolation is probably ineffective because, consider the impulse response, a single sample standing up above the DC level: the line interpolates from zero at the previous sample, to peak, then back to zero on the following sample. A considerable amount of energy has been cut off from the rectangular-topped sample. Some of this energy has been moved to the base (the triangle base is 2 samples wide, versus a rectangle of 1), but due to RMS, the peaks are weighted more heavily so the total energy is significantly reduced. Instead, something like a cosine, with the peak/valley aligned to adjacent samples (i.e., a Hann window), might give a fairer weighting, while smoothing the edges (reducing aliasing/harmonics beyond Fs/2). Note that any upsampling/windowing process is equivalent to simply filtering the signal, so, a convolution in time domain (the fairly trivial FIR filter), multiplication in frequency domain (FFT, mul, iFFT), or passing it through an analog (or equivalent digital, IIR) filter of similar response. We could reflect on the noise generators as well. These chips have a short period PRNG (usually LFSR I think), using relatively few bits so the samples loop fairly often. This is used for anything from rumbling, thunder and explosions (at low sample rates), to wind and cymbals. The short repeating period gives it an unexpected tonal quality, while adjusting the sample rate gives it a sort of crude adjustable lowpass point. We could consider many ways to generalize this instrument: use a higher sample rate with a longer period; use white noise (i.e. more than 1 bit per sample); use true white noise (analog samples or TRNG); variable bandlimiting instead of sample rate; and various types of filters to implement that bandlimiting (a PRBS spectrum has a sinc envelope, or others could be tried as well). Nice work, cheers!

the low sample rate of the triangle wave actually increases information, not reducing it. If you look at the FFTs of either, the "lowres" one actually has more to it than the high-res. Ultimately we're just comparing different timbres here. It's a matter of taste which one you prefer.

@@cpK054L I think they mean that the low sample rate introduces more harmonics from the corners of the steps (mentioning FFTs is drawing me to that conclusion, not necessarily that I agree btw) but yes generally if the sample rate is below the frequency of the signal you decrease information. Anyways, in the case of rather ordinary regular waveforms, you could argue that it doesn't matter much. The triangles and squares the 2A03 is trying to generate could as easily be restored simply by linear interpolation between peaks in a ramp circuit or multivibrator. It isn't quite the same as taking an analog song and digitising it then playing it back through a DAC. Compositions were generally written with the specific limitations in mind, because doing otherwise is just plain stupid. So generally there was never any "missing" information in this context. The low-resolution computer noises were your instruments. Y'all seem to have the relationship here reversed. Interestingly, had Ricoh exposed the APU channels to the board, they totally could have used analog synthesis and mixers to get a solution similar to what is in the video. It looks like their triangle channel is using an incredibly simple ladder (hence the 4bit resolution) probably driven by an internal counter ping-ponging back in forth like a sweep circuit controlled by the internal APU registers. I know the 2A03 has been depackaged and die photos are around so someone probably does know exactly whats going on inside it. Also, the inherent "filtering" of creating RF output or passing the audio through RCA and the television likely did have a softening effect on the soundgen that is absent in emulator output. If nothing else, a slightly sluggish slew rate in audio channel amplifiers would have also "smoothed" the triangle though it would have been more muddy than crisp.

I dont remember much because I dont apply this to many things but the FFT of a cosine would be the dirac delta at the positive and negative frequency so if you mix it with the sample frequency you would get 4 dirac deltas, and if undersampled youd have band crossover causing an alias. I actually dont remember the fourier of a triangle...wasnt it doesnt like every third harmonic of a sine wave? Pi/X amplitude where X is the harmonic? Edit just looked it up and it is an absolute disaster.... Also I believe you were right... there should be no encoding data in these waveforms... the NES could just be using DDS removing the need for decoders if the sound waves are just being played direct to the speakers.

If you buy Lagrange Point and listen to the music while playing the cartridge, you’ll encounter that thel VRC7 has an extra noise: a relatively high pitched ringing that slowly changes in pitch over time. It will be a different pitch each time a track starts. I made a recording of the whole soundtrack through the line output of a Sharp Twin Famicom years ago and gave it to the user nensondubois who uploaded it here to KZread. The volume at which the 2A03 and expansion audio get mixed together in the analog domain is different between different Famicom models. The pre-1986 models and the Twin Famicom have a more equal balance, and the later Famicoms with an FF logo on the front and the A.V. Famicom make the expansion audio much louder. It seems from various official soundtrack releases by Nintendo and other companies featuring music with expansion audio that the behavior of the later models is what became the preferred behavior, as you might expect since those were what the contemporarily-produced Famicoms sounded like. The official Konami Lagrange Point soundtrack CD from the time is that way as well, but I prefer the balance of the earlier models for that soundtrack, so that’s why I used the Twin Famicom for my recording. It’s on a game by game basis, really. Like I like Metroid on the older models and Zelda on the newer ones. I personally like the brighter sound of the triangle wave with the stair-stepping more. But the RF output of the Famicom tends to have a strong low-pass filtering effect, and the Twin Famicom features one as well on its line audio output, so I wonder how much smoothing of the triangle wave that would do. The NES’s line audio is less filtered, but I’m sure most people playing those games prior to the late ‘90s or so probably did it through RF as well. Not to mention the vast majority of people using their TV’s speakers rather than quality standalone ones, further obscuring treble frequencies and distortions.

Thanks for this experiment that displays wonderfully all the atmosphere and vibe that the “imperfections” bring the music. Hearing the direct comparison really drives home how sterile the more “perfect” wave shapes make the music.

Hearing the triangle wave as a proper triangle made me feel at rest, like I was finally able to relax.

Really let's you appreciate how Journey to Silius devs (and probably others) composed their music to play with the janky triangle wave in mind to make some very rich textures and harmony not present in the smoothed version. Thank you for making this video, otherwise little things like that couldn't really be appreciated

I didn't know anything about this subject before I watched this video and I was absolutely enthralled the entire time. Great vid!

As a synthesist first and a game purist about 8 octaves later, I absolutely love everything that you did here. I especially loved the hi-res version of Demon Seed which expressed some overtones that were overshadowed by the original aliasing.

Other than some of the mixing issues, I prefer the sounds of the original. A lot of the music sounds like it was composed around these so-called "imperfections". That said, it is a cool experiment to do and a nice educational video.

Fearofdark also known as Steve is a person that has truely changed my life. I originally found his song rolling down the street in my katamari from a meme about pelo back in like 2019 or so and I thought not much about it until I started listening to more of his music until his songs became embedded with core memory’s in my mind that if I even think about it his songs will definitely be there. I hope he never stops making chiptunes because god this guy is probably one of the best chiptune composers I have ever listened to. So thank you Steve, Xavi

Exit Plan is a genius album

This just became one of my top 10 favorite channels. The algorithm is really putting in work these last few months for me.

Extraordinary work you did here! Love this video.

As a "producer" I am interested in synthesis and sound in general. I guess that's how this got in my recommended. This is very interesting and kind of inspiring. I have subbed with notifications lol. Please create more things like this

This is so interesting. As someone who has worked a lot with FamiTracker, it’s so insightful to hear what these instruments would sound like with fundamental issues removed. Almost 10 years ago, I took a 5 minute wind band piece and put it into FamiTracker-it took two instances of a custom edited file with all of the expansions playing at once and a utility I found that syncs the playback of multiple instances of FamiTracker. Of course it’s not realistic, but it was amazing to hear it all come together, especially after months of working on it. I wonder how different it would sound with these changes.

What a wonderful material! Thank you so much for this piece of work.

I was playing Mario&Luigi for the GBA on Switch Online and I remarked they chose to emulate the music & sounds very faithfully. It's still got that gameboy crunch. Really sells it for me.

Pretty sure gba music is sample based so they had no choice

bruh Fearofdark is an amazing chiptune musician, all of their songs make me feel like I just acheived something like reaching the end of a great game.

This is akin to removing the hiss from cassettes or the line noise from a guitar amp…technically cleaner, but missing the mojo of the format. It turns it into something else entirely. I will say that the VRC7 improvements are much needed, as the original just sounds objectively “bad” imo. But the quantized saw and triangle waveforms on the VRC6 and 2A03, as well as those specific square wave duty cycles they chose, are what I would argue to be the “sound” of that chip and thus why it is nostalgic in the first place. I did work on a game that was to emulate a nintendo GBA and I went to great lengths to emulate (what is imho) the horrible sound of that chip. Why? Because that’s a large part of the nostalgia factor. But this is a fun exercise and I think something worth exploring of its own merit! Cheers! I forgot how good FoD is. Man that tune is fantastic and sounds so much better without all that ugly aliasing.

Exactly! I fully agree with you.

The first 2 square waves at the start of the video made a fire beat 🔥🔥🔥

This is probably unrelated to everything about the video (on a RELATED note, super awesome work with the triangle wave dude, loved the examples as well) but the short song used as an example at 0:52 goes so hard

The sine and exponent tables have a canonical formula to how they were generated but the way they are mixed would probably make it a bit bothersome to preserve timbre if the core you're basing it off of doesn't have some kinda floating point alternative Envelope Generator iirc. If you want the formulas, just look for the OPLx decapped project. From there you can modify the equations to be more suitable for 16 bit sampling instead of the 10 bit or whatever it was they had. At some point I would like to do the same thing and expand the sine tables for my own fm synth core while still being mostly compatible in timbres with existing voice parameters for the 4op OPxx chips. I believe Steve Snake already managed to do this ages ago in Kega but of course none of that is open source.

Hello, nobuyuki! Thanks for your insightful comment. I actually have the formula for the exponent and sine wave tables, but the operations that are used to manipulate the values in the table before it is mixed together uses a lot of bitwise computations. Ideally, I would use floating point operations instead of pulling the values from a table. But trying to understand how the values are transformed before it is output and implementing them using non-bitwise operations is still a bit too difficult for me. Still, it is far from impossible, and will still try to do it in the future!

The Solstice title theme by THE Legendary Tim Follin, sounds great but I've always fantasized about what would he do if he had the additional sound channels from the Famicom Disk System. With your improvements, it will sound even better! On second thought, the white noise is actually built into the song and is used to represent the cymbal "tsshh" sound

The sound quality difference is astounding. Fantastic work!

Def YT suggested this vid to me. Enjoyed it! It caused me to ponder what it would have been like back in the day for the musical composer to work with the NES/etc. programmers. Obv not all things were musically possible. 6 channels, many limitations. It is astounding that they were capable of doing all that amazing work with the tools that they had at the time.

Honestly everything sounded perfect up until you played coffee zone. It was kind of designed with those audio flaws in mind which makes it sound a bit more disappointing played through cleaner outputs. The quantization of the fm chip makes it sound like some kind studio synth and the triangle makes a bit more of an impact to the melody with the hiss. That said, this is a really cool concept. Makes me curious what a c64 would sound like.

Hello, there! I am very glad to hear your thoughts. To make it short, honestly, I agree :D I cannot say whether Fearofdark composed the song with the audio flaws in mind (I can only say so once I ask him) but I completely agree that the added harmonics on the triangle wave (which actually makes the triangle wave much more easier to hear), and the quantization noise (which my father describes as sounding like the rain) adds something special to the mix. I personally prefer the track without quantization noise, but I cannot deny that the jagged triangle wave adds something special. All in all, actually, I prefer the original sound of the chips. That is their identity, and removing all the flaws is just like stripping them of their identity. It's what makes the VRC6 different from the 6581 (which doesn't have a jagged sawtooth wave). It's why I keep hardware recordings of the chiptune I like ;-) This was just a fun (and probably interesting!) experiment and I thought it was fun doing this. Makes me also glad that I was able to hear how they would sound like if the faults were all removed, be it for the better or worse. Thanks for your comment!

IDK, it kinda sounds like a dreamcast Knuckles song with the new output. Probably not the intended vibe but definitely worth hearing, at least as an alternative.

Pure. Chiptune. Bliss. I have very sensitive hearing, and I can hear sounds up to 18.2kHz. Because of this, I tend to bias my headphones towards top-end clarity, but those hisses have always been very noticeable and almost distracting to me. Hearing The Coffee Zone without any of that extra noise had me smiling from ear to ear the whole way through! I would love to hear more classic chiptune pieces covered this way! I can't say specifically which ones, I listen to so many I can't choose >. I know there is some debate about whether we should improve upon older media or keep the original as is without modification, whether technically inferior or not. I say that both is good, and I like the ability to choose between the original version and any remastered releases. Your channel has been a hidden gem. The ability to visualize the waveforms of each instrument/channel adds so much more fun than just listening to it, and I love how it adds to critical listening. I think your edits were very well done. Less is more, and I wasn't lost at any point of the video. I have been subbed since less than a hundred, I think, and I have been showing your visualizations to people who are curious about the kind of music I listen to. Rant over. Excellent video, excellent choice in music. 10/10 would watch again.

Hello! Wow, 18kHz! That's awesome! Best I can go is a bit short of 16kHz. Still, I consider myself an audiophile, and I can feel your concerns! Some people actually disliked The Coffee Zone without the quantization noise. My father is one of those who liked the hissing, and he said that it sounded like rain. Still, just like you said, I think that neither is better than the other! I like how smooth the noiseless version sounded like, but I also like the retro feel of the one with the original noise. You mentioned critical listening with the aid of the individual waveforms. I never thought about it before, but I think it does help! For example, many C64 tracks add a very short burst of noise on bass notes, which I only noticed after seeing the waveform. I guess it adds a bit of a percussion feel to the bass instrument, making it sound closer to a pick or slap bass, I think? Thank you very much for your support. I really appreciate it!

@@KYLXBN Yeah, I definitely agree the quantization noise is part of the NES sound. I compare it to playing 240p/480i consoles on a crt vs upscaled on a flat panel. While it is easier to distinguish pixels and colors on the modern screen, the crt blurs the picture and interpolation creates extra visual effects whether intended or not. The imperfections create character, making simple scrolling backgrounds and animating sprites feel different than on a modern display, without even taking into consideration frametimes or input lag. It is neat you include your father in your projects. Sounds like a great guy, and I don't think I would have connected the extra noise with rain. Now I want to ask my dad what he thinks, considering he grew up playing NES games!

The amount of creativity and inventiveness that went into early PC and 8-bit console sound design is astounding.
