Pitch

Hi

Does anyone know how to pitch up sound to double frequency in realtime.
100Hz pitch to 200Hz and 400Hz pitch to 800Hz.

Thanks

play it faster?
what are you trying to do this with?
are you talking about pitch-scaling or resampling?
try http://www.dspdimension.com
or http://www.mega-nerd.com
for useful resources on each
