Hi, forgive the intrusion. I had a similar idea a week or so ago but am not a software engineer. I built and installed Asterisk on my LFS (Linux From Scratch) server. I have a cheap analogue PSTN (x100p) card and the standard EC with the Zaptel modules didn't do much - echo was bad... I installed the OSLEC canceller from David Rowe (http://www.rowetel.com/ucasterisk/oslec.html) which is simply a kernel module that interfaces to the zaptel module. It is brilliant! Worked a treat... On my desk I use the Polycom Communicator (a handsfree combined mic/speaker) USB audio device. And although most of the EC and noise suppression technology is apparently in their Windows only drivers, it works "OK" on my Ubuntu Desktop, but I do have some problems with echo. I was wondering if it would be possible to use the OSLEC module in a more "generic" way (perhaps within ALSA) so that it could be used to provide EC services to almost any audio device or as a "driver" simply for my Polycom C100s... Is this a sensible idea?
