Echo and Noise when capture

Apr 26, 2011 at 6:39 AM

I am working on an singing program by using NAudio, I wonder anyone have good ideas/ experience to share with me about how to do "Echo Cancellation" and "Noise Supression" during capture and play in real time.  appreciate in advance.

NAudio doesn't include any built-in algorithms for echo cancellation or noise suppression. Echo cancellation can be quite tricky to implement. Noise suppression is a bit easier - you typically use a noise gate. You could have a look at to see if there is anything that can help you.

Hi Mark

Any plans to implement AEC filter in NAudio?

I'm afraid not at the moment, you'd either have to write your own managed AEC, or wrap a third party effect.
