I've played with audio with a PJRC Teensy 4. They have an audio
design tool on their website; you drag and drop mixers, filters etc,
and it creates a skeleton "C" program to implement it.
I used that to create a CW filter/translator for my KWM-2, which
is horrible for CW as is - because the sidetone & received signal are
1750Hz. I mix it down to 650Hz and do some serious audio filtering.
All in software.
