Hello,
I'm trying to achieve the best possible noise cancelation in Flash 10.1. I'm using the microphone to capture vocals while music is playing and I'd like to try to eliminate as much of the music as possible. I've been searching around for some type of "squelch" or a DSP algorithm to help, not not too much luck finding anything directly related to noise cancelation. I've heard subtracting right channel data from the left channel is sometimes an option, but the amplitudes have to match up perfectly or something?
This is so far the best code snippet I've seen on the subject, and it just uses Microphone properties to try to eliminate as much echo and noise as it can without sampling data: http://snipplr.com/view/21868/flash-microphone/
Anyway, any advice on this topic would be appreciated.
Thanks!
