A trick I learned to save on CPU was to render (in reaper it means to convert a track into a audio file like FLAC) a track on the highest oversample rate possible. That way I get that sheen of a higher sample rate but save my computer from getting sweaty and depressed.
Do you render or freeze each individual track at a higher sample rate, or just render your final mix at a higher sample rate?
Im assuming he means individual tracks.
@@NACHOTHEIST Correct, for each individual track. Very handy for dense mixes :D
I can’t find words to describe how much I’ve learned with you and Miami. My mixes got into the next level. ❤
This is a great video
damn, listening on my laptop speakers i can totally tell the huge difference when you turn the oversampeling on and off.
The video I needed. I never really understood what the deal was.
With this video I fell in love with non-oversampled saturation. That velvety high end! 😍
Is that a new JST plugin we're seeing?! 🤔
Yupp lol JST Heat. It’s a MB Saturation/Distortion plugin. They already released it for early access members. If you want to jump in on that head to their social media there should be a link somewhere to join early access. Otherwise I think it’ll probably come out on Monday if I had to guess?
@@CloudburstStudio awesome 👍 thanks for the heads up
I've been oversampling since 2019.
Does this introduce Gibb's phenomenon?
I feel ultra conflicted about the use or gains of oversampling. To all the up & coming producers / mixers, I’d say you need to get 99% of your mixing & mastering game down before you even consider what oversampling can (or cannot) do to your process. Otherwise you’re chasing something so finite that really doesn’t do a lot to improve fundamental things like well played parts, instruments in recording condition, appropriate mic’ing, EQ & compression etc etc - am I being too cynical?
Nope, I share the sentiment. Like trying to put a glossy cherry on a half-baked cake.
It's a one of the thousands of decisions you need to do as a part of your production. I really love non-oversampled saturation on vocals. But it's just my taste.
Yooo might want to calm down on the de-essing
On the voice over?
@@joeymusic yep, all the esses are eshesh
That was quite a drastic example with that saturator. I'd say, that's probably not the saturator you wanna use if it's that aggressive :/
We had to make something drastic that people can easily hear.
96 Khz, 256 buffer and it';s ok, 96 Khz love more, than 44.1/48. Mini latency and perfect sound
Try it)
But oversampling mostly introduce pre-ringing or long post-ringing due to the filter is used.
It's bit more difficult, because that ringing (oscillation in time domain) applies just to frequencies affected by the filter. For oversampling process, you need a steep low pass filter. Frequency range from zero attenuation and full attenuation, where such filter operates, is called transition band. For a high quality filter that's typically between 20k Hz and Nyquist frequency (eg. half of working sample rate - 22050Hz). No other frequencies will be affected by the filter (incl. time domain oscillation, which is just different "view" on the same process).
So in another words - although you can see ringing on graph, when you feed the low pass filter with special measurement signal (typ. Dirac pulse / contains all frequencies), you won't hear it. It's bit specific case for those filters at top of audio range - if you'd use for example different steep linear phase filters towards bottom of audio range, it is different story - there you can really hear pre/post ringing as a smearing with certain signals. So be aware of that with crossovers or notches down low.
I’ve done many tests by printing out impulse, kick drum and other stuffs through oversampling process, I could clearly see the pre-ringing before the transients. It seems for me the ringing happens not only at the Nyquist. Another thing I discovered is oversampling with IIR filter creates much longer post-ringing than FIR filter.
Hi @@TianpeiWang Sorry a long day :) As I've touched before, seeing something doesn't equal hearing it. You can easily see pre-ringing in time domain after oversampling - for example before leading edges of natural instrument transients, mouth clicks, flat-top clipped samples, artificial impulses (Dirac) or say at simple square wave signal with steep edges. All those signal examples exhibits great deal of high frequency information, which gets affected by low pass filter near Nyquist. Essentially when you see a waveform with abrupt rise, sharp edges in time domain (has high rate of level change - EE term for that is slew rate), it also means the particular signal there contains high frequency information - both are directly related. So it's natural, you'll see the filter is working there, but at the same time that can be well over hearing range.
Let me suggest you a different test, if you're curious ;) Take some signal with decent amount of HF information (like complete mixed track, drum stem etc.), then process that with resampler with linear phase filter (usually default choice). First upsample it say 4 times (like 44.1k to 176.4k) and then again back to the original rate. Now make a classic null-test in your DAW. Line up both files to different tracks, flip the polarity at the second one and put FFT analyzer on the master bus. If you did that correctly, then all you should see is difference signal lies pretty much just between 20k and Nyquist - eg. exactly where LPF filter works. No other frequencies were affected by the process. Important part for test is, that resampling process affects signal level, so either be sure there is enough headroom at input file for possible peak level increase, or better output all resampled files as 32bit float to avoid possible clipping. The other important bit is, that resampler has to be correctly latency compensated, so its output perfectly align with original file for null test to work. But it usually isn't the issue with common high quality resamplers nowadays (Voxengo R8Brain, SoX, iZotope, built-in algo in Reaper etc.).
It makes music sound fresh and energetic
Im fed up with instructions like "it depends" or "use it here, but not here if Xbis < or = to Y on a Monday with a full moon"
Oversampling doesnt always make things better and sometimes it makes things worse..
😡
That was the point of the video.
@@joeymusic I know, you got it right! Just saying, that's too often what I hear
