About Acoustic Echo Canceller
Hello. I'm from Federal University of Rio Grande do Sul - Brazil and I'm trying to adapt speex_echo.h (speex-1.2beta3-win32) to our video-conference software code. We are working on amplitude values, but I realised that in order to AEC works, one has to convert amplitude to frequency and filter the echo frequencies. So, my question is: Do I have to manually convert amplitude samples to frequency...

compiling echo cancellation
dear all I got this error when I try to use libspeex in visual studio. when I include speex/speex_echo.h, it complains about unresolved external symbol _speex_echo_state_init. And when I include mdf.c into the source, it generates whole bunch of errors. Any idea? thanks so much --------------------Configuration: audio - Win32 Debug-------------------- Compiling... mdf.c C:\Documents and Settings\Mi...

echo suppression
There is experimental echo cancellation code. Look in speex_echo.h and mdf.c. Unfortunately there's no sample code, and I don't think anyone's had much luck getting the echo cancellation to work at all. Would anyone like to prove me wrong? I'd love to see this work! I know it's really hard but just tonight the person I was talking t...

fixed point AEC
Thanks Jean, I missed that detail. I have a few more compile errors if you could help me with it => In function speex_echo_state_init in mdf.c I am getting error: "undefined reference to exp". I don't see a fixed point implementation of "exp". Can you point me to the correct files. I am using the following files from speex 1.2 beta1 => mdf.c, math_approx.c, misc.c, fft_wrap.c, kiss_ff...

PJProject Bundled Update
As you know, the ability to use a bundled version of pjproject was introduced with Asterisk 13.8.0.

SpeexJitter and TCP/IP
...ancellation filter. I get some artifacts, the echo is removed, but you can here some metallic voices in background. Jean, in your test client you are using UDP connection and SpeexJitter to make sure UDP packets are in order. What if I use TCP/IP, do I still have to use SpeexJitter when using speex_echo_cancel ? regards hs

Some problems with mdf.c
Hello... I want to ask you something about your software implementation of MDF filter with DTD machanism. (mdf.c speex_echo.h files) My questions are: 1. What are theoretical (using in your articles) equivalents of index symbols from your program? 2. Could you describe or give me an algorith which was using during software implementation of the MDF+DTD 3. How I could freeze MDF by means of DTD block. Best regards...

fixed point AEC
Analog Devices sponsored a fixed point version for AEC which was posted early this year, but it seems from the source code that the fft routines are still in floating point. Is the port still not complete or am I missing something? Has anyone out there ported speex AEC on RISC architecture? Please let me know. Thanks in advance, -Deepa -------------- next part -------------- An HTML

To symbian and speex developers! Building instructions
Hello to everyone! During building speex library for Symbian OS I encountered some problems. All thess problems can be solved by modifying the speex sources. I don't have access to SVN repository of speex, so I will just describe the changes to be done: 1) mmp file in symbian derictory misses windows.c sources. You need to add this string into speex.mmp: SOURCES windows.c 2) Symbian OS

More Speex (pre-processing) Options
Hi, So I have had a chance to delve deeper into the new pre-processing code- I was also able to get VAD, AGC, Denoising, etc working inside of the current release candidate (1.0.3). For some reason, the 1.1.2 release didn't properly encode/decode in our system (on windows) and I haven't had time to determine why. In any case, all of the features jointly work very well- great job! I
