Acoustic Echo Cancellation

Morning all,

I've done a search, but couldn't find anything relevant. Are there any free tools out there for doing acoustic echo cancellation on audio files?

TIA.

not in this lifetime

cancelling echoes requires (near) complete knowledge of the room the audio was recorded in. anything else is a guess.

however, you can "push down" an echo using a fairly gently acting noise gate (dynamic compressor/expander).

audacity (free) might be able to handle it. i use Audition (not free) for this kind of stuff.

additionally you can try a heavy noise/hiss reduction - it'll remove echo as well, but you'll probably end up with a "tin can" sound.

I had a feeling that might be the case.

Thanks!
