Hello all,
I just thought this might be interesting to some of you, as a demo of what
Overflow can do. I just "wrote" an Overflow program (.n) that performs real-time
audio processing. It reads the soundcard input, normalized the volume (lowers
louder sounds, amplifies lower sounds), and sends the result back to the
soundcard output. It takes less than 5% CPU on my Athlon 500 at 44.1kHz/stereo
(I use chunks of ~10 ms). Note, you need a full-duplex soundcard and the latest
version in CVS to try it. Any electric guitar player here would like to help me
write distortions and other effects?
Comments are welcome.
