Hi Jean Marc, We are running the speex echo canceller code on a Windows Mobile smartphone using a TI OMAP 201MHz 850. We are making voip calls and audio is working without echo canceller code. Simply adding the following 2 functions whether the echo cancellation is wired in (ie we use the output frame ) or not performance becomes terrible. Note 2 separate threads are used to handle audio.

Hello Ashhar, thanks for your reply, but i'm a bit surprised. 1- Does it mean that it is possible to make a Real Time Encoding/Decoding with SPEEX on iPhone ? 2- What parameters have been used (QUALITY, SAMPLING_RATE, BITRATE) ? and what kind of CPU load do they measure for that ? Thanks by advance, Vincent ----- Original Message ----- From: "Ashhar Farhan" <farhan at

vincent, it should work out of the box. real time speex should work on the iphone as it has a really fast arm cpu (and speex works in realtime on even the 201mhz arm cpus). while compiling, remember to define the fixed-support support and you are all set. narrow band (8khz) and 8kbps bitrate will work very well. while you are at it, pse send the xcode project file to include in the tarball. - farhan On 11/10/08, Vincent Burel <vincent.burel at vb-audio....
