    he has great points. however his test at the end did not show him using distortion and other plugins that would cause foldback. in other words all he did was up-sample and dither with no processing. The aliasing only occurs when using low sample rates with a subar plugin not optimized well. nontheless if in 44.1 one should oversample the distortion plugins. if it has no option to oversample, then use a plugin like metaplugin.

    David, one thing should be clarified. Yes, when you're printing tracks with outboard gear, you want highest sample rate possible. But ... To do tha when you're running 44.1 files through the gear you need to capture them into the second DAW (with higher sample rate set). Otherwise your DAW automatically downsample new tracks back into 44.1 to fit the session. So... When you have 44.1k tracks and run 48k session for example (and want to capture your tracks back with 48 into the same DAW), you need to upsample all tracks to 48k b fore even starting the session (even that upsampling doesn't add anything new, just plain zeros). Am I right?

    What if I am only ITB and want to record/export/bounce a VST synthesizer with no plugins on the insert?
    I believe since no ADC involved in the internal exporting and it is happening at 32 bit floating point; I can and I should record individual tracks as loud as possible with the maximum possible dynamic range.
    For example reverbs and delays could benefit from being recorded hotter ITB if we want to preserve couple of extra bits in them (correct me if I am wrong). Thank you!

    Thank you for this video! I actually just watched the 1st video before this one and replied to someone’s CLA comment and I mentioned aliasing Haha! I too have been a victim of the aliasing myth going around the internet. It had me very interested for about a week and I read tons and tons of info about it.... and it got really frustrating. So many different opinions. Lol
    Then I read an article about the producer for the Weeknd track “The Hills” and how he used the decapitator plug in all over that mix. It has over a billion streams! No one seemed to care about aliasing with that track haha. So I’m thinking no one really cares at the end of the day.
    The only thing I can think of is that maybe the soul can hear aliasing lol. I have no clue! 😭 The song is really what matters most and that it’s captured in a way that sounds “good”. That aliasing shit really had me messed up for a minute!

    Thanks David. Good job.
    One comment though (or maybe I misunderstand you), you keep saying that extra sample resolution "adds zeros" to upsampled data. That isn't actually what happens. If zeros were inserted, for example when going form 44.1 to 88.2, then the data would drop to zero between every two sample values along a waveform, which would end up being noise. Depending on the specific conversion process, it will probably interpolate the sample values to fall in place at the new rate.
    Of course, if you are saying that it 'adds zero information', then I misunderstood, as that is correct. :)

Watch a lot of your content. that said I can't help but wonder with the analog setup you have in the background, that MOTU only has eight in and outs, just the analog gear in your Wes Audio Super Warrior alone takes up all your I/O. Are you using the AVB somewhere else? because it doesn't make sense that you would limit yourself to 8 I/O from the MOTU in a professional setup where time is money.

I'm interested in buying an analog tape machine, but I also love the sound of those Neve 542 tape emulators. I'm really interested to see if the Neve's really have that tape sound or if they are best used for saturation and not replacement of tape.

    if I mix something in a very high sample rate to avoid aliasing, then I render those tracks out at that high sample rate, and then bring those high sample red, renders back into a lower sample rate session to convert to a lower sample rate, in an effort to avoid aliasing from plug-ins, does the act of downsampling a mix in and of itself, create aliasing?

    • @mixbustv
      @mixbustv  Год назад

      No but you're WAY overthinking it, let alone this would be an absolute nightmare workflow, what do you do this for every single processing for every single track? And most important it's useless, use oversampling on the plugins that do have it, and that's it. Not all plugins need oversampling because not all plugins cause aliasing, not all aliasing can be solved with oversampling, not all aliasing is even audible or has significant impact on a mix. Downsampling does not cause aliasing anyway

You say that it`s a good idea to recapture the signal after the gear at the highest possible sample rate. Let`s say I have all tracks at 44.1k and use analogue gear. Wouldn't it make better sense to upsample those tracks to 48 before running analogue gear so they are already 48k? Thanks a lot.

    Plug-ins do operate better and sound better at 96kHz. I mix in 24-bit 44.1kHz, so I decided to test this theory (using hardware at 96kHz is much better than 44.1kHz.).
    Yes, 96kHz was significantly better, even after importing both files into a blank 24-bit 44.1kHz. They were both processed using an external hardware reverb unit, in bypass mode - NO plug-in processing. Eventhough 96k sounds better to me, I don't have the CPU to use plug-ins in those types of sessions, so I'll cop out to using 32-bit 44.1k. I assume that I'll hear a significant difference! But anyways,
    Peace and happy mixing!

    Hi David, a question I always had about oversampling: is it necessary to use the internal oversampling of each plugin separately? Or for example, just using oversampling in the Fabfilter L-2 placed at the end of a master is enough to stop the aliasing that the converter will cause? this doubt really drives me crazy haha

    • @mixbustv

      No is not necessary, and in the particular case of brickwall limiters, oversampling can change the sound and it doesn't necessarily sound better. For distortion/saturation plugins, usually oversampling makes a big difference, for the better.

He's usually pretty negative on analog emulations and I used to really dislike his video's but the more I watched it, the more I was agreeing with him. (I still don't agree about his views on the interfaces and stuff.) then he made a video on alliassing. And I think he did very well. He explained well and even proved what he was saying. He later came back about it on his 192khz video.
      And 10 years ago I was 12. I got into audio engineering when I was 19 so I wasn' t there during the discussion. And right now I am agreeing with him. Especially since I've recently played around with analog gear and heard that it sounds better than most emulations.
      Even money is starting to become less of an issue when picking between the two since there is a website called Mix:analog that allows you to use analog gear for set amount of time while being very affordable. Yes there are still limitations but their team is also trying to solve those as well.
      But I am very open to be convinced otherwise. Especially since I like to be informed about these kinda of things.

      The worst part is I should've known better as a plugin designer hobbyist, as I somehow picked up this old myth only just recently. I was searching why my current project sounds much cleaner at 48kHz. I now suspect it must be the internal filters that move up, or the resonance bump cramps less early and sounds therefore cleaner.

    I find this talk about the sampling rates being a potential threat for less experienced mixers to become less focused on their skill of mixing itself. It is much better to mix at 44.1 paying more attention to your balancing, eq/compression/depth creation /panning/ fx skills than caring about the sample rates. Focus on your mixing skills and mix at the sample rates you got the session in. If you are the producer starting recording the song from scratch then use 96khz if your computer is powerful enough and don't think about it anymore. Just my 2 cents

    • @mixbustv
      @mixbustv  3 года назад

      Mixing at 44.1 even if you're give files at that sample rates makes little sense, *especially* if you're using outboard. 48 has a big impact and improvement over 44.1 with negligible CPU hit. Is this simple concept a threat? Really? If that threatens a brain then mixing is definitely not for them. Recording at 96? For what? 48 is more than enough, 88 if you want to really go overboard, 96 is silly.

    • @chrislysiak9561
      @chrislysiak9561 3 года назад

      @@mixbustv This would be true if we lived in a perfect audio world. Unfortunately, we do not. Not all converters are created equal, especially if someone is using the cheap ones. Almost most of them sound much better @96k over 48k. I personally use both Apogee Symphony 16 for OTB mixing and after summing with my Dangerous 2 Bus, I record it back through my Universal Audio 2192. I tried recording at every sample rate and at least on my converters and to my ears nothing beats 96k. When it comes to upconverting the session from 44.1 to 48 for mixing as you suggest, unless you use high-quality conversion software, you will destroy the quality of audio for sure. Not too many people own this kind of software because it's expensive. I'm not sure about you but I am also a producer and I'm using a bunch of software synths, which to my ear sound radically better at 96k. That's why my advice is to always stick to 96k (or possibly 88k if you hear no difference) throughout the whole process. As a summary let me paste the official opinion of mixers like Bob Clearmountain, Joe Chiccarell, George Massenburg. Even though they speak about surround sound mixing here I do not see how surround sound audio would differ sample rate-wise from stereo audio. They state: "The mixing engineer may assume three things. First, the highest practical rate
      should be chosen for original recording and mastering. Second, all known
      resampling (sample-rate conversion) techniques are to some degree audible,
      although recent work has shown that with great care and provided with
      considerable DSP resources, one may resample, both up and down, very
      effectively. And third, an integer ratio conversion (i.e., 96kHz to 48kHz, or
      88.2kHz to 44.1kHz) is more likely to have fewer resampling artifacts.
      It must always be understood that when upsampling audio (converting to a higher
      sample rate, i.e., from 48kHz to 96kHz, or 44.1kHz to 96kHz), one will never
      restore the upper octave filtered out at the original A/D conversion (i.e., when one
      converts at 44.1kHz, there will be little signal above 20kHz from then on).
      However, there are possible benefits to be gained from upsampling when
      playback occurs. In any event, sample rate is not the sole, nor even the most
      significant factor in perceived audio quality; the design and quality of the A/D and
      D/A converters makes the most important sonic difference. A state-of-the-art
      audiophile 44.1kHz / 16-bit converter can easily sound better than a 192kHz /
      24-bit converter built using an inferior chipset. "

      We work with lower SR file at a higher SR project because plugins work better at 48, not converters, converters have the same chip, the same specs the same everything at any sample rate, what changes is the quality of the *recorded* file. As for how much difference and to what point, again, there is plenty of literature showing drawbacks at 192 which would be such minimal difference from the one happening between the bare minimum, 44.1 and 48.

You are advocating upsampling, not me.

If you don't agree with this, then we have to agree to disagree. When it comes to the sound of the plugins, it all depends on the plugin. Some indeed sound better at 48 while virtual synths almost always sound better at 96k. I yet have to find one that sounds better at 48. Anyway, I do not wish to argue here.
