I refuse to believe that none of these people ever heard of Nyquist, and that noone was able to come up with "ayyy lmao let's put a low pass on this before downsampling".
Edit: 2 day old account posting stuff that doesn't pass the sniff test. Hmmmm... baited by a bot?
in ~30 years of my work in DSP domain, I've seen insane amount of ways to do signal processing wrong even for simplest things like passing a buffer and doing resampling.
The last example I've seen in one large company, done by a developer lacking audio/DSP experience: they used ffmpeg's resampling lib, but, after every 10ms audio frame processed by resampler, they'd invoke flush(), just for the sake of convenience of having the same number of input and output buffers ... :)
Haha wow, I guess that gives a very noticeable 100 Hz comb-like effect... noone cared to do a quick sanity check on that output?!
