...o load the OSLEC echo canceller into my current kernel.

Hi Is it possible to use only the speex echo cancellation module w/o using the speex codec? Here's the scenario: 1. I have my voice recorded in PCM audio file format 2. I want to cleanup the recorded voice by removing any echo included in the audio file/buffer 3. can I just use the ff APIs? - SpeexEchoState* speex_echo_state_init() - int speex_echo_ctl() - void speex_echo_capture()

Hi Yes, it's absolutely unnecessary to use speex codec. You can encode the echo cancelled auido data with any codec you want. The Echo Canncelation API is here - http://www.speex.org/docs/api/speex-api-reference/group__SpeexEchoState. html I would advice you to look at speex_echo_cancellation function but you will have to sync playback and capture streams by yourself. I've used GSM, iLBC and Speex codecs with Speex AEC and it wor...

I'm experiencing a very unusual problem with a few of my sipuras. They keep over heating after minimal usage. I unplug them and let them sit for 15 minutes and it starts working fine. The other way around is that I put a fan on it or something to keep it cooling. Has anyone else experienced this or are they just defective units? Regards, Mohammed Salim EZZI Telecom, Inc.
