Downsampling – PS Audio
https://www.psaudio.com/pauls-posts/downsampling/
Downsampling is audibly trivial compared to mixing with 16/44.1 tracks, given all the processing that typically goes on in a mixing session. Ironically, one of the reasons that modern mixing and mastering sometimes sounds awful (even on the 24/96 master) is that engineers can push the compression to ridiculous levels without introducing obvious …
Downsampling audio for use in Machine Learning - Signal ...
https://dsp.stackexchange.com/questions/47152/downsampling-audio-for-use-in-machine-learning
Whether or not you are downsampling (instead of just decimating) has nothing to do with classification performance but rather, it is to preserve (as much as possible) the information contained in the signal. When changing the sample rate of a signal, you need to account for aliasing. Otherwise, the signal will be distorted in such a way that it would be …
python - Downsampling wav audio file - Stack Overflow

First, you need to import 'librosa' library Use 'librosa.load' to resample the audio file librosa.load(path,sr) initiallly sr(sampling rate) = 22050.If you want to preserve native sampling rate make sr=None. otherwise the audio will be resampled to the sampling rate provided

(OLA hop size = FBS downsampling factor = N). •Advanced audio compression algorithms (“perceptual audio coding”) are based on critically sampled filter banks, for obvious reasons. •Important Point: We normally do not require critical sampling for audio analysis, effects, and music 19 applications. We normally only need it when
Q. What’s the best way to downsample? - Sound on Sound
https://www.soundonsound.com/sound-advice/q-whats-best-way-downsample
I want to ask what method you consider to be the best for downsampling. I have started working at 24-bit and 96kHz and am noticing the benefits in quality, but I’m confused about the best method for getting back to CD quality (16-bit, 44.1kHz). I have no problem understanding dithering 24-bit audio to 16-bit, but am less clear about downsampling.
