Linear interpolation when resampling #3

Closed richardjwild closed 6 years ago

richardjwild commented 6 years ago

The current resampling algorithm does no interpolating whatsoever. On an 8MHz ARM2 in 1991 this was understandable but really, in 2018 we can and should do better. A windowed sinc function would probably be overkill for 8-bit samples but linear interpolation should provide a nice increase in audio quality.

Closing because now implemented.
