Mathias,

For the filter, I'd suggest a moving average. It's really cheap on CPU
cycles if done recursively and works extremely well. As for compression,
if you can't figure that out yourself you deserve to fail the course. :)

Hello,

does anyone know where I could get speech enhancement algorithms written in
C (typically for hearing aids, but I need that to integrate to a telephony
server for my diploma project)? I'm looking for noise reduction algorithms
and also for dynamic range compression algorithms...

Thank you for reading!
