commercial acoustic echo cancellation licenses

Started by mv.b...@gmail.com March 18, 2011
Hi -
Could anyone please let me know if there's a company out there that has solved acoustic echo cancellation reasonably well for 44.1KHz stereo audio, and probably provides licenses to their tech?
Thanks!

Could you please provide more info: what is the max echo tail ? Do you need to support different sound-cards to do the capture and playback ? Any maximum MIPS requirements ? Floating point allowed ?
The SPEEX codec has a very nice Acoustic Echo Canceller, which is written
under a BSD license. If you're looking for a commercial license to limit
your legal liability (patent infringement, etc.) there are a number of
contractors a vendors to choose from. I can recommended Bolom LLC (
http://bolom.com/).
