Fix for conversion of 8-bit audio #21

Open Schevv opened 1 month ago

Schevv commented 1 month ago

When converting wave audio that is 8 bit (either input or output format) with audioop we need to care about the signedness of the 8-bit audio (see docs for audioop.lin2lin)

We need to add bias to pyaudioop first so this will continue working after Python 3.13 where they will drop the audioop module.

Maybe it is easier in that case to replace the call to bias with a simple loop? It is simple to implement for the edge-case (8 bit) we have here. That is easier than to create the bias function for the general case and having to maintain it?
