Playback feature

[125scratch]

I was able to use this program to convert a few audio files to LPC data, and I noticed the README.md mentions a playback feature was added, but I can't seem to find a way to activate it in the GUI, how would one go about playing back the LPC data?

Try to install pyaudio as it is used to playback samples to audio card.
pip3 install pyaudio

It does not work, you get these errors.
note: This error originates from a subprocess, and is likely not a problem with pip.
