"To get ahead of myself a bit, `scipy.signal.resample` *sucks* _for audio resampling_. That becomes apparent quite quickly - it works in frequency domain, by basically truncation or zero-padding the signal in the frequency domain. This is quite ugly in time domain (especially since it assumes the signal to be _circular_).\n", "\n",

It also is quite flexible and is often able to change to a different channel count or bit depth at the same time. Here's a code sample that resamples an MP3 file (usually 44.1kHz) down to 16kHz. The MediaFoundationResampler takes an IWaveProvider as input, and a desired output format:

A practical and well-known example results from the fact that professional audio equipment uses a sampling rate of 48 kHz, but consumer audio equipment uses a rate of 44.1 kHz. Therefore, to transfer music from a professional recording to a CD, the sampling rate must be changed by a factor of: (44100 / 48000) = (441 / 480) = (147 / 160)
