In Python you can use librosa, or you can write a script that uses ffmpeg or similar. If you want to reuse an already trained model this is critical, as the neural network will have learned features based on 16kHz input. Webexample 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.

The "right" way to do it when downsampling is to first apply an anti-aliasing filter and then decimate the signal but when upsampling, you first upsample and then apply interpolation (which can also be expressed as a filter). Various platforms provide functions to do just that (e.g. Python, MATLAB ). " - Downsample audio python
