Active Noise Reduction as Software--possible? Answered
While on vacation last week, I was trying to watch a sophisticated, complex movie (something with Muppets) on a laptop and was having trouble hearing the audio through headphones, due to the general loudness of my family.
Is it possible to actively reduce noise through computer software? I assume that the programming itself would not be too complex, but I don't know if the time taken to process microphone input and use it to modify audio output would be too slow. The only place I found through Google that discussed this was a forum wherein the members couldn't get past the concept of attaching a microphone to a headset. I also found a schematic with instructions for building headsets, but I would prefer a .exe file.
