Re: [Linphone-developers] Speexec.c

[Simon Morlat]

Hello,

This 320 stands for 160 samples of 2 bytes, *6 it represents 250 ms at 8khz 
sampling rate.
This if statement is a workaround for the case where there is too much data in 
the input 0 of the echo canceler. Normally this should not happen (and I 
never saw this warning), but for other people who are developping new 
applications on top of mediastreamer2 this can be useful to understand what's 
happening and to preserve a correct behaviour.
So if this happens the input is purged and the echo canceler reset.
