Switch to a faster library for dynamic resampling

[juanmc2005]

Looks like torchaudio.Resample is not very fast compared to other libraries implementing resampling in python.

See https://github.com/jonashaag/audio-resampling-in-python

Looks like we could switch to soxr and get a 10x speed increase.

hi Juan. I found a cheap way to avoid resampling if you're using pipewire is to force the rate with

pw-metadata -n settings 0 clock.force-rate 16000

that's for microphone reording.

There's also an aubio library which provides resampling. It provides a python module
