WTF is Dither?
Тәжірибелік нұсқаулар және стиль
A practical exploration of dither, with no maths in sight.
How to use dither. How to check your dither is working correctly. Whats the difference between a native DAW dither and a posh dither like MegaBit+ from iZotope? Should you dither when rendering MP3 files?
Once you know this stuff you'll never have to worry about it again.
I used Reaper as usual (plus Sound Forge) but these principles apply whatever DAW you're using.
Intro / outro music is "Memories Evoked By A Smell" from my album "Impostor Syndrome", available in all the usual places. Bandcamp link:

I feel like a broken machine repeating this, but again you've shown that you're a real audio ENGINEER. Gearsluz and other audio forums are so stock full of old wives tales, rumours, misconceptions and "i just feel like it man" attitude towards these concepts that it's sickening. People just need to realize that what you feel or think you hear is never what really is happening and why. Be like Dan, be scientific, be well read... be an engineer.

If you're "sickened" by that then you don't have a very strong constitution. In other words, who cares what other people do? When amateurs mess up it means more business for people who actually know stuff. You're smelling a little bit like an elitist there brah.
1.) Use 16-bit dither for creating 16 bit files. 2.) Use 24-bit dither for creating 24 bit files. 3.) 16-bit dithering should be done only once. 4.) Dithering is the very final step, even after sample rate conversion. 5.) Use 16-bit dithered files as resources for latter mp3 conversions. 6.) Don't see 'Dither' like a 'Disaster'. Music production has many other steps that deserve more attention. No point of overly worrying about this. _learned all these thanks to Dan_ ❤🙏

@@VAEOMMusic I also use Studio One, but I'm used to dither by FFProL2 plugin. So for answering this question, I had to watch another KZread video to find how Dithering can be enabled in StudioOne itself (if you are not using a specific plugin to Dither). Here's what I found :- 1. Go to "Options" window (accessible via "Studio One" dropdown below title bar at top). 2. In "Advanced" category, under "Audio" sub-category, enable *"Use dithering for playback and audio file export"* 3. Hit 'OK' (the window will then close with changes applied) Since you've enabled dithering now, once you are exporting your MP3 (at 320kbps 44.1kHz), the file such exported should be automatically dithered. However I'm not familiar with this method, since I do dithering by FFProL2 plugin (so the aforementioned option for StudioOne's own dithering isn't enabled in mine). I assume you know how to export. If not ; well it is done by "Export Mixdown" window accessed by the "Song" dropdown below the title bar at top. In the "Format" region of that window, you can select "MP3 File", and set your preferred attributes (44.1kHz / 320 kbps). I suggest to use Constant bitrate. Since we're supposed to choose a 'bitrate' here (rather than _'bit depth'_ as in Wave exporting), I don't think there's any "16bit / 24bit / etc." choice to be made during mp3 exporting. Besides, mp3 's can't be in 24 bit, which is why if you're supposed to create an .mp3 file using an existing .wav file, it's advised to use a 16bit .wav for that conversion (not a 24bit/32bit .wav)

@@VAEOMMusic *If you can export 'mp3' directly from the DAW (with dithering enabled), that's totally fine.* No need of exporting 'wav' and then converting to 'mp3'. But if a DAW can't export 'mp3' directly (such that you have to export a 'wav', then convert it to 'mp3' by a *SEPARATE CONVERTER APP* ), there you have to make sure that 'wav' file (taken from the DAW) is 16bit.
Preparing an extensive tutorial (with examples, verification tests) isn't easy - it's exhausting, boring, time consuming. etc. Imagine bearing all that stress singlehandedly, for making a free tutorial for others! That's an unbelievable attitude👌👌❤ Again, thank you very much, Mr. Dan

It says right on that page that it uses the LAME encoder. So FL studio will most likely behave exactly the same - just as any other software that probably implements that encoder. Or any software that uses mp3s properly for that matter.

you're doing such a great job in really showing and comparing the technical details in a simple, understandable way! So great! Also there's way too many people on youtube repeating the same cliché phrases and prejudices about Mixing without really double-checking and I'm so so thankful that there's people like you, who cut through all the bullsh** and keeping straight to the facts.

As someone from the RF engineering world, watching these videos is just fascinating. There's so much in common between audio and radio, the same fundamental mathematics and a significant overlap in terminology, but there's enough differences that it feels almost uncanny at points.

@@Will-qx9vm Probably the two techniques I'm most surprised don't see use in the audio space are frequency mixing and quadrature/IQ sampling. Sure, additively shifting the frequency content of a sample is less "musical" than the logarithmic pitch shifts that audio people usually reach for, but unlike pitch shifting there's no phase discontinuity problems you need some extra intelligent algorithm for, and the effect is basically free computationally speaking. And, while audio files wouldn't actually be smaller if stored using an IQ sample format (since the frequency content of audio is so close to baseband), it _would_ make nearly all effects processing algorithms more efficient, and enable dealing with phase issues in less awkward ways. (In fact, a lot of algorithms literally start by resampling the input to IQ, and end by resampling IQ back to the output format.)
@JazzyFizzleDrummers

We do use frequency mixing/ring mods in sound design/synthesis but its generally far less useful for most applications because it 1) isnt much good on polyphonic sources because it doesnt preserve the ratios between notes. We usually work in EDO tuning systems like 12tet and destroying those relationships render those shifts pointless 2) It requires back of the napkin calculations that slow down production. You'd need a program to streamline it regardless.

Well, except that it's a very artificial demonstration showing a technical detail that's more or less completely irrelevant in the real world... How many people do you know who listen to music at +60 or +108dB? Dithering is free, so there's no penalty in using it, but except for some really extreme cases it's also mostly unnecessary.

@@ToddBeal Well, his #1 rule at 9:54 is "Always use dither when creating a 16bit file". That should also have had the caveat that his 24bit rule has : "no one will ever know if you don't". As I said "Dithering is free, so there's no penalty in using it". But to quote Monty Montgomery (of Xiph, creators of ogg/vorbis and opus, fame) : "No one ever ruined a great recording by forgetting to dither the final master". The "Digital Show & Tell" video on the Xiph site is well worth watching when it comes to dithering. That segment starts at the 9 minute mark.
Glad this channel popped up in my recommendations. Concise & specific content is what I look for on KZread now a days. Most of what I want to find is kind of hard to find w/o sifting through a whole bunch of filler or is only beginner-intermediate levels of expertise.
Fantastic stuff. I always love to see a new video from Dan.
Thank you for providing us with so much well versed knowledge as always Dan!
There's a floating point in your life, in which you feel safe to write that this video about 16 bit sorcery is not a smoky unshaped burst of noise. - Thank you for dithering us into the topic.
Incredible run-through, sir! Thank you for all the concise, methodical and astoundingly illuminating videos-it's so helpful and reassuring to finally get (somewhat) of a grip on these concepts.
That mp3 ending really blew my mind! Awesome video with great insights, thanks!!
The way you broke all this down finally made it make sense. Thanks for showing the examples and tests of how you tested the daw dither. After testing the stock FL Studio dither compared to Ozone, the Ozone was slightly smoother with the noise shaping engaged.
This completely explains the weird stuff in the stems of a client of mine, no wonder I didn't have a clue what was happening. And it probably is the last time I will ever come across this again in my life, thank you for solving the mystery Dan!

Lovely, been doing audio for years and never quite really got my head around dither. This was very explanatory and informative. Thank you sir.

Great explanation for intricate facts that were well beyond my scope before watching this video. Thanks, Dan! *Thumbs up*
Real thorough but clear explanation. Thanks!
Hi Dan, Just a little message to tell you that I am amazed by your videos. As an amateur musician & home studio "sound engineer" ;-) , these are a lot of subjects that I was aware "in general", but the way that you dive into them, with visual/audible examples, is really excellent. Now I really understand the details of dither, oversampling, non linear plugins, etc... and the real repercussions on our audio needs, which is the most important. Now I know how and when to use these tools efficiently. More than that, your english flow is perfect for a non native english speaker (I'm french). Thanks again and keep the good work.
I and many other people learning audio are so, so grateful for you Dan!! Thank you so much. Great examples presented clearly and gently as always.

This is an excellent video! Really filled in some important details for me regarding things I've been wondering about for some time. I'll be making changes in the way I do certain things. Maybe they won't be noticeable, but if there's a right way to do it, and a wrong way, might as well do it the right way.
Insightful as ever, thanks Dan.
Came here to watch another tutorial. Found the new benchmark for tutorials in general. Thank you!
This is great, and I have only one comment. Even with highly dynamic material nobody will hear 16 bit truncation distortion on decaying reverb tails. Just as you had to amplify the snare files by 60 dB to hear the differences shown in this video, you'd have to raise the playback volume at least 40-50 dB to hear that distortion on very soft passages. Of course nobody does that while listening to music, unless they're doing experiments like the ones shown here.

My process has become this: 1. Export my mixdown file with no dither as a 32-bit WAV file 2. Import the file into RX for phase correction, save again as a 32-bit WAV 3. Pull the file into my DAW for mastering. 4. Now, when exporting the fully mastered track, I can export a 16-bit WAV or FLAC file with dither, only having applied it once with no loss of dynamic range or extra dithering earlier in the process This is most likely overkill, but will ensure the best end product consistently when dealing with any content that includes a large dynamic range
Your amazing work shows that most other explanations on youtube and especially forums are just the result or opinions of wannabe-creators. To me, making music is fun and should not be too serious or get stuck by the will to sound more professional than I am currently. Getting better and learning the stuff behind the DAWs is interesting and a longer process. The information to understand that world has to be from guys like you!
