similar to: zaptel echo canceller preload patch

Hi, I have a box with Debian Sarge, Asterisk 1.2.1 (and zaptel 1.2.1) and a TDM2400P with echo canceller. I installed the card but no echo cancellation is being made...seems like the echo canceller module does not work, infact the software cancellation is working. My zapata.conf has echocancel = 128 and echocancelwhenbridged = yes but no echotraining parameter which gives a warning. I found

I have a channelized T1 coming in from our telco, terminated onto a TE405. There are three channelbanks serving internal analog extensions, and about 10 Cisco 7960s. I have no reports of echo on the analog extensions (as expected). The 7960 users complain of occasional echo (seems like 1 in 5 calls). Only the SIP user hears the echo, not the caller. I have echocancel=yes, echotraining=yes,

I've spent the last week or so troubleshooting echo problems at my Wife's business, and I've been able to clear up about 99% of the echo, but there is still a little residual echo that I can't seem to "tweak out". The users describe it as "buzzing or crackling", but what it sounds like to me is a slight echo, but just of one syllable of the word.

Perhaps that's because I have some problem understanding the documentation, or dunno how to fine tune it. I tried to use the echo canceller to cancel out echo in case it is present, but when I tried it, it gives me echo even there is no echo at all, and the echo is more serious if there is echo present. I'm using speex with JNI, I shall give more details if needed. But i just want to

Do the zaptel drivers need to be told >NOT< to use the software echo canceller when using a TDM2400p card with hardware echo canceller, or does the driver figure this out by itself?

Jean-Marc, BTW, the problem #1 is not unique to the speex echo canceller. It has also occurred on other ec's I've tried, most recently the CANEC ec from dspalgorithms.com. - Eric Scott > -----Original Message----- > From: Eric Scott > Sent: Thursday, July 28, 2005 9:11 AM > To: 'Jean-Marc Valin' > Cc: speex-dev@xiph.org > Subject: RE: [Speex-dev] Problems

Hi all, speex is great,echo canceller in speex is great,when I test echo canceller with testecho.c, it is much better then the echo canceller demo in intel IPP 5.1,but when I use the echo canceller in a real voice chat program for win32(16khz,20ms,winmm or portaudio or directsound), it is not work. Who can help me? I will pay money for a demo using dsound with source code.Thanks a lot.

hello jean-marc and everybody, I keep getting no results when trying to use speex_echo_capture, speex_echo_playback and speex_echo_cancel in a multi-threaded application, as suggested in the manual. Though, the cancellation works properly when i use a file with human voice for far-end input and the same file with echo added in SoundForge for mic input. When i try to insert and remove silence

I wish to preserve the state of the echo canceller engine when it is in a converged state, in order to use this for a later, separate VoIP connection. However, any jitter in processing delay from playback to record might make this impossible. From the manual: Latency and algorithmic delay Every speech codec introduces a delay in the transmission. For Speex, this delay is equal to the

I'm having trouble getting the echo canceller to work and I'm hoping some one can get me started in diagnosing what's going on. The symptoms I'm seeing are these: 1. If the NES is silence (i.e., no echo, no speech), the ec puts the FES back into the audio. 2. If the NES is similar to the FES (same speech words), the ec doesn't seem to remove the echo. 3. For case #2, I pushed

Hi, I wanted to know how the speex echo canceller can be used for multiple channels audio. I am aware that support had been added for multiple speakers and multiple microphones. Is there any documentation on how speex_echo_state_init_mc can be used in conjunction with speex_channel_decorrelate?

Does anyone know what this means? It is in DMESG, and we have people complaining about echo. Disabled echo canceller because of tone (rx) John

hi! In your experience what is the best choice for echo canceller ? Which one should work better: STEVE, STEVE2, MARK, MARK2, MARK3, KB1 ?

Hello! I have problems with audio in conference zap sip, I have choppy audio. I believe this problem is cause by de echo canceller from the fonebridge that I use in my system. Can someone explain me how I can disable the echo canceller form the fonebridge? I'm using dual port T1/E1 foneBRIDGE2 Thanks!! -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi everyone, I've just released Speex 1.1.9. The main change in this release is the echo canceller work sponsored by Tipic Inc (http://www.tipic.com/). It is now possible to do acoustic echo cancellation and obtain good attenuation after a short adaptation time. This has been tested at 8 kHz, but it should also work at 16 khz and above, so give it a try. There were also some fixes to the

Jean-Marc, That was my first thought as well. However, I double checked everything and it wasn't reversed. I also reversed it to see what would happen. In that case, the NES came out unchanged. (This NES was the original FES.) Any other ideas? Also, do you know what algorithm is used? - Eric Scott > -----Original Message----- > From: Jean-Marc Valin

hi all, i want to use the echo canceller feature of Speex 1.1.10.
