Hi all,
Aran we're also using your -very neat- code to mix some sounds from wav files; works without a hitch but I get pbs when I try to do things similar to low-pass filters to the result of the mix (or any of the input signal). I did divide the UInt32 into left & right Uint16 channels. Multiplying these by integers woks fine, volume goes up. But every other arithmetic screws up the signal, including a simple division (even as a binary shift). The sound ends up being vaguely recognizable but with artifacts.
Any clues as to what I'm doing wrong?
Regards,
Guillauùe
