As far as I understand, re-sampling and re-quantizing are not trivial
operations in the general case, or am I mistaken?
For example, converting from signed 16-bits samples @ 48 kHz to [-1,1]
float samples @ 44.1 kHz
Several "buzz words" spring to mind, such as interpolation, dithering,
anti-aliasing, noise shaping, etc.
Anyway, it sounds ;-) like an interesting project. I'd like to look into it.
