Hello, I am using speex codec for sending voice over zigbee (low bandwidth wireless network) on ARM platform. Current I am facing issue where I have standalone sample application working but when used with application that sends data over the air it has quality issues. I cannot increase bitrate more than a limit and I am encoding stereo 8Khz sampling rate data. I am using variable bitrate with max limit of 42K. If I use variable bitrate in standalone sample application it works fine but going with max 42K makes the quality poor for the recorded voice. Does anybody has any suggestion on what are the best parameter for low bandwidth network that allows to keep the quality good like original? regards, Ketan -------------- next part -------------- An HTML attachment was scrubbed...
