I also would like to contribute more on FSComm when I have more free time. I actually "stoled" some code from FSComm to a client I was working on. We use a headset so AEC is not a big deal for now. But I still would like to see AEC work for this. Actually someone reported ECHO even with a headset I haven't confirm. Is it possible to get OSLEC work on Windows/Mac ?
In addition to AEC. I also found PA lacks the ability to change the sound device volume. I tried to control sound devices in QT but haven't find a way. Ideas on this? Echo is a big problem with headsets, especially those with the mic up near the earpiece, and a tube to the mouth. Its also a problem in traditional telephone handsets. A good IP phone handset should have an acoustic echo canceller cleaning up its mic signal. A lot (even many expensive ones) don't, and produce considerable echo if you turn up the handset volume for the hearing impaired.
