Re: [Linphone-users] Echo cancellation on linphone 3.3.2

[Maris]

Well, try with delay 200, tail 150 (ms) and framesize 128 is default and  
OK. You can specify these parameters in .linphonerc
The delay is most subject to experimentation, because it not only  
compensates for the audio path delay, but primarily the buffer delays from  
speaker output and mic input.

You can also keep top -d1 running in another terminal window and watch if  
CPU usage increases drastically when echo cancellation is on. Please  
report these figures! (ARM and MX27) - thanks.
