The odds of being able to actually hear a difference in noise between playing back uncompressed and losslessly compressed audio, even in the lowliest of low-end systems, are probably no better than simple chance-especially because most of the noise generated by a CPU or other microprocessors will be far outside the audible range. But if one were *really* concerned, there's a dead-simple solution: uncompress your audio files before playback.

It is wrong to say they are outside our auditable range ,which they are, but they do not only present there they distort all the frequencies right down to the other end of the spectrum the sub sonic tones. In preparation for my next upgrade I bought an expensive linear power supply and while waiting to get an up market streamer I currently have my Wiim pro powered through it. To my surprise it is the biggest single step in my sound quality yet. (though obviously "chance" of my previos choices will have affected the new synergy) Honestly buying a faster streamer at this point is more about curiosity, about matching my DAC's capability than it is about sound as I already love mine.

My format of choice is 24 96 Flac, I bought many years ago I box set a five CD by the band Rush I ripped the albums in wav to my Apple mMac mini played back through Audirvana It sounded Ok, I noticed on a site that same item but in 24 96 and costing just 20 pounds. I bought it and downloaded it from High Rez audio, my go to site, for many years, the difference was night and day whereas the Cd;s sounded sharp and top these downloads had a analog quality to them and sounded great. To my ears 24 96 Flac sound better, than other formats aside from blu ray audio, I don't need some geek to show me reams of graphs to show me otherwise, the sound is sweet powerful detailed and for 5 albums very cheap.

If audio devices get better in isolating noise is there still a function for power plants?

I had a lot of noise on my PC when playing FLAC or MP3 files through headphones, or even when not playing any audio when the CPU was busy. I put a ferrite on each side of my headphone cable and now the noise is gone.

I took the test between lossless and lossy 320 Kbps and could not tell the difference or actually liked the 320 Kbps version better at times, depending on the type of music.

Paul gave a palpable answer on this topic, not the gobbledygook I expected.

Your video has gotten me to thinking about sound quality and CDs. I think the amount of error correction actually going on during playback has an effect. When I was selling audio in my younger days, the place where I was working had two copies of the same CD that we used on the sales floor. One of them got quite scratched up, so badly we doubted it could play. We tried it - and it played with no skips or obvious errors in the output. Then we played the one what was "perfect." It sounded much more open, much better imaging, like an upgrade. These were the same CD, from the same source (it was a demo disc from one of our manufacturers). We concluded that it must have had something to do with how much error correcting the CD player had to do with the scratched CD. What do you think?

@alexanderjones9766

2 жыл бұрын

The reason it would sound different is that the scratched disc has uncorrectable errors. The CD player tries to hide this by interpolating the missing samples. If there are too many missing samples, it will skip, but if only a few are missing, it will play smoothly but at a reduced quality due to the interpolation.

I have some low bit rate videos that sound surprisingly excellent. I need to place myself mentally in a seat further away from the performance and it all makes sense. Lossless theoretically allows you to replicate the actual band's sound in your room....That is, if you want to disturb the neighborhood. Lossless can sound like an actual band is playing in your house if your speakers and equipment are up to the task. My absolutely favorite live performance was heard sitting in the balcony at the Fillmore East in 1968. Some of my most disappointing were when I was right up close. All excellent musicians. A great DAC on a good system can make a lower bit audio sound very satisfying... at a desk top. Now? If you want to hear real bass and drums in your home? I would imagine that lossless would be essential... Theoretically, lossless makes that possible. Which better suits you is the question.

Is the digital signal coming from the transport perfect or is the transport processing a perfect signal before its processed to analog via dac, I’m confused. If the signal is coming from the transport is perfect and not proceed, why would I pay thousands for a music transport. Can any body explain.

I'll answer this for you Jim: if it sounds different, it wasn't lossless.

There might be some issue with old hardware that shits itself when ithas to decode sth

FLAC uses more processor power to encode than decode, it was designed that way for a reason. If a person's processor is struggling to decode a FLAC file enough to cause an impact on the sound quality, that processor is not fit for purpose. In any case, a CPU does not work harder on a FLAC file than a WAV one because the WAV is bigger and there's more in outs to consider. "On my PC, using Sysinternals Process Explorer (the benchmark tool for CPU usage analysis), playing a WAV file in Foobar required a scant 0.327 seconds of total CPU time from a single core of my multicore processor. This works out to about 0.2% CPU usage. Playing the exact same file in FLAC format, required 0.312 seconds of total CPU time-also about 0.2% CPU usage. These numbers are essentially the same, and the FLAC number is even slightly lower. Why? It’s likely because the CPU has to read half as much data with FLAC compared to WAV. But these numbers are so small, they really don’t matter." thewelltemperedcomputer.com/KB/WAV-FLAC.htm

I work with big data, so the time it takes to complete a process is important. The test in your quote is a fail because the overhead for operations not directly involved in decoding are also captured. The test needs to be run either as a Monte Carlo (a million or so repeats) or the file needs to be concatenated repeatedly up to a reasonable percentage of the RAM (like 5Gb in a 16Gb system). By doing both methods, one can actually discover what the overhead is for both file types.

If there is a difference after loading the track into memory, it's incredibly minute, and with more and more devices supporting it there's not much reason to use uncompressed formats. Plus, with lossless formats you can always transcode if you need to. Let's say you want some music on your smart watch for a workout but it doesn't support FLAC. Just load up a DAW or dedicated transcoding program to convert it into a support format.

This has more to do with the low fi and low cost audio electronics on the Mac's logic board than any CODEC or DAC. The analog stage is not protected from what is essentially a digital broadcasting station inside any computer chassis. If you are old enough to recall Soundblaster cards....the high end ones were encased in steel cases on their daughter boards. This was to shield the audio outputs. Even so, it rarely got better than 70dB of signal to noise ratio.

Even a dog or cat would never be able to tell the difference between FLAC/ALAC and WAV/AIFF.

Personally...MP3 audio for example, sometimes when converting CD quality to basic MP3, you can get "sound-drop"...i.e. the melody might start off loud/clear...but when the percussion/beat kicks in...it suddenly goes quieter and you have to turn it up to get the same effect. However...If I want practically "CD Quality"...and I go CD-to-WAV, its as nigh-on CD-quality as I can get...as the audio-data isn't as compressed. However...when saving to external hard-drives it uses more space compared to a compressed audio file of say an MP3 version. Its all down to the quality of the equipment used and personal choice....

What does this galvanic isolation mentioned in the video have anything to do with digital audio cables? Does anybody realize that ethernet is galvanic isolated by design? The differential pairs offer common mode rejection and go through both inductive isolation through the transformer and capacitive isolation. The DC coupling is done at the PHY. A cable has NO SOUND. A cable has RLC, period, end of story. If you do the math the amount of RLC has to be GROSS to impact the low frequency of 20kHz. If your cable is magically changing the sound either 1.

Noise is a major issue in this day and age with our homes full of RFI… that draw power to reproduce as they contaminate the music signal. I wonder how many here still think that electrons flow? 💫

If I've understood correctly, Aurender digital players first uncompress and then copy uncompressed audio files to their second internal SSD disc, and play music from there. So files can be stored on their primary (large) hard drive in compressed format, but they are always played back uncompressed from the smaller SSD drive.

The display will have 0 effect on the performance of hardware from an electrical and computational point.

For ripping music the load of the PC won't make a difference even in theory. Compared to music playback it's not a realtime process, it decodes and encodes the data without any time pressure. Anyone who claims this is an issue probably has no idea how often processors reliably switch between tasks all the time. And while I don't have the expertise of the guy in the video, I kind of doubt his claims about digital cables where he doesn't even explain how he thinks it would make a difference - if you have enough electromagnetic interference to flip bits in digital cables the real problem is probably not the cable. If you're paranoid about it get the slightly better cables with some shielding, but no need to overdo it. What is correct is that electronic devices can influence each other (or even themselves) and this is mostly relevant when they work with high frequencies or analog signals. So it's not bullshit to have certain devices not run from the same power supply, for example it's the reason external DACs tend to be less noisy than soundcards built right into the computer. To decide how far you wanna take this use your own judgement and hearing. A ton of the marketing bullshit is in that area.

But now, decades later, my hearing craps out around 13-14khz. So ultrafine sound (I'm a 95% audiophile) is simply imperceptible to me. This problem is normal with aging. Do you find it has affected your standards as well? And I can't quite tell if MP3 VBR-2 is the same as -4 to my ears, but the -2 sounds the same as lossless formats to me. And my degraded ears.

I use sometimes a DAP player and have various music files and to be frank, I cannot hear any difference (not using MP3) the chip in DAP players is designed to handle any files without loss of quality and so are most modern chips used today in Audio equipment. Use Roon as a library in my home set up and come to the same conclusion. However, music recorded average to bad one can hear on most music files used and play. The quality of the recording is the key.

I thought the difference in audio quality was a result of the decoder and not the encoder itself (digital). Back when I used to do some blind tests (excuse me a decade ago) it was more than apparent the differences between FLAC and Monkey's Audio, but... oh no wait it wasn't a blind test... there was an manual equalizer involved, hmm...

I used to think the same way. But WAV files don't allow for metadata. Metadata makes organizing and searching digital files soooo much easier.

Mp3 for life.

I can only attest to my experience. I find a big difference betweem MP3 or WAV vs FLAC. But, in attempting an A/B test betweem a CD and the same FLAC encoded cut, via my streamer, the FLAC doesn't hold up. Good but, as the say 'no cigar'. BTW. love the 'Fruedian slip'!

I use galvanic isolation on my stereo system. I crank up the volume to max and go next door to listen.

They shouldn't sound different IF and this is a big if, the lossless file was created using the exact same wav or aiff you are comparing to. In most cases there is no way to know how that lossless file was made nor can you get your hands on the uncompressed file they stated with. The reason why I want to go with apple lossless is to get all the tags and album art on the phone and in the car. I can't do that with .wav files. My collection is archived in .wav (remastered by me) so I will be able to compare them because I'm making the lossless files, not downloading them. Before I start that project I will need one of the new iPhones with 512gig of storage but as soon as I get one I'll try it.

When you take a continuous signal, try to break it up into millions and millions of zero and one levels (whatever that means) and then try to re-produce what you have now converted to the digital domain back into a continuous or analog signal how can this task ever be easy. This was a really good question and an even better answer.

Lossless is lossless and as long as the DAC gets the exact bits from the master there is no difference. And lossy can sound any level of worse depending on the degree of loss. MP3 files can be compressed to different level of degree and more compression means smaller files but also more audio fidelity losses, for example.

lossless is lossless but if the processor has to do more operations in order to process one type of file over another, there is a difference in the output of the processor. It doesn't have anything to do with being lossless, its just about how hard the codec pushes the DAC. What i mean is that its not the difference in files but in DACs.

@@mleczor The output of the processor, that is a PCM stream with a given bit resolution and sample rate, is not depending on the amount of operations done by the CPU, if the format is lossless.

You are clearly unaware that not all digital cables (such as USB, coaxial, and optical digital) are made alike and can affect the final sound. Sending a digital tape/disc signal or data file from a source/computer/transport to a DAC is not as simple as pushing a stream of ones and zeroes that is either _perfect_ or _completely inaudible._ - Can you not fathom that a poorly-constructed or lesser-quality cable could fail to conduct all of the tens-of-thousands of samples per second _perfectly_ in all cases? - Did you know that coaxial cables are susceptible to noise and have to be specifically Ohm-rated in order to reliably carry a digital signal? - Because USB uses a varying voltage to send audio, did you know that poorly-implemented USB controllers/connections and poorly-constructed USB cables can result in audible errors? If you didn't know any of those scientifically-proven *FACTS,* you might want to get educated before making additional condescending comments towards a respected, knowledgeable, audio professional.

The noise that a PC architecture is creating is the sum of numerous digital pulses involved in just running the operating system with various drivers, GPU, ethernet, memory and so on, and audio decoding is your least concern. If digital noise from your computer is an actual problem (EMI or through wire), changing codec is definitely not a solution. You need to isolate your gear e.g. using TOSLINK and most certainly, don't power your DAC by the power from your computer.

Only "lossy" file systems differ. Heck, you can rip a CD using different settings which will create MP3 files of vastly different qualities. But FLAC, ALAC etc are identical except for the proprietary crap which deliberately breaks some formats from certain devices. DRM etc. Noise comes into picture immediately AFTER your DAC converts the digital format into analog.
