python - Downsampling wav audio file - Stack Overflow
https://stackoverflow.com/questions/30619740/downsampling-wav-audio-file
To downsample (also called decimate) your signal (it means to reduce the sampling rate), or upsample (increase the sampling rate) you need to interpolate between your data. The idea is that you need to somehow draw a curve between your points, and then take values from this curve at the new sampling rate.

If you want to downsample a Hi-Res 192 kHz audio to 48 kHz (e. g. for an iPod Classic), you should use the rate effect with linear phase (the default one) and the highest quality (VHQ). You can use the --guard option to automatically invoke the gain effect to guard against clipping.
Q. What’s the best way to downsample? - Sound on Sound

I have no problem understanding dithering 24-bit audio to 16-bit, but am less clear about downsampling. Before attempting to master (once the mix is done and in stereo format) I take the file and downsample from 96kHz to 44.1kHz, but there is a definitely noticeable degrading of the high end when I’ve done this.
Sampling in Matlab and downsampling an audio file ...

Going back to the previous example of ‘gong’ audio vector loaded in the Matlab variable space, the downsampling operation can be coded as follows. >>M=2 % downsample by 2 >>y_down = y (1:M:end); % keep every M-th sample. Note: Downsampling↗ is not same as decimation. Decimation↗ implies reducing the sampling rate of a signal by applying ...

Can someone suggest the correct way to downsample please? I’m guessing someone must have solved this but couldn’t find anything conclusive on the forums. This is my workflow: pretrained model is 0.5.0; extract audio files from the video file using ffmpeg. ffmpeg -i original.avi -ab 160k -ac 1 -ar 16000 -vn audio.wav. The clips are at 44 ...

Decrease sample rate by integer factor - MATLAB downsample
https://www.mathworks.com/help/signal/ref/downsample.html
Description. y = downsample (x,n) decreases the sample rate of x by keeping the first sample and then every n th sample after the first. If x is a matrix, the function treats each column as a separate sequence. y = downsample (x,n,phase) specifies the number of samples by which to offset the downsampled sequence.
