In digital audio, what matters is the audibility of interpolation error between samples. Since Shannon’s sampling theorem says it is possible to restore an audio signal exactly from its samples, it makes sense that the best digital audio interpolators would be based on that theory. Such “ideal” interpolation is called bandlimited interpolation.

To resample an audio waveform from one freqeuncy to another, you can use transforms.Resample or functional.resample . transforms.Resample precomputes and caches the kernel used for resampling, while functional.resample computes it on the fly, so using transforms.Resample will result in a speedup when resampling multiple waveforms using the …

Upsampling (or interpolation) is the process of converting from low to higher (for example, from 44.1 kHz to 48 kHz); downsampling (also known as decimation) is the process of converting from a high frequency to a lower one (for example, from 96 kHz to 48 kHz).

resampling or interpolation? - Stack Overflow
https://stackoverflow.com/questions/17852639/resampling-or-interpolation
In the case of audio, these are the amplitude values sampled at each time point. Resampling is used to either increase the sample rate (make the image larger) or decrease it (make the image smaller). Interpolation is the process of calculating values between sample points. So, if you resample an image you can use interpolation to do it.

The interpolation factor is simply the ratio of the output rate to the input rate. Given that the interpolation factor is L and the decimation factor is M, the resampling factor is L / M. In the above example, the resampling factor is 147 / 160 = 0.91875. 4.1.4 Is there a restriction on the resampling factor I can use? Yes.
