similar to: Linker error in Code for Echo canceller of Speex 1.1.10

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

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

Good day! I'm creating HDL IP CORE (for using in FPGA) for theora encoder (now only I-frames). I don't undestand one moment. Now i develop such stages: 1. From RBG(byer) to YCbCr converter 2. DCT processing (8x8 pixels blocks) 3. Quantizator of DCT coeff. 4. Zig-Zag of quantized DCT coeff. and now i have uresolved last stage of compression - how i must send 8x8 blocks to huffman

hi Jean-Marc, I just updated from svn and it looks like there are some errors in the speex.mmp file. the filters.c is duplicated, and the fft/kiss.c files are still missing.. /alfred Jean-Marc Valin wrote: > Applied in svn.

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 to asked me, "Is there ever

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,

Hi, Ref the disucussion on IRC yesterday; here's a patch which makes a bit more data from the analysis of the preprocessor and the echo canceller available. For the preprocessor: - Size of power spectrum. - Power spectrum and noise estimate of the previous frame. These are given as squared values, so sqrt() to get values in the 0->32767 range. - Current amplification level

Applied in svn. Thanks. Jean-Marc Alfred E.

As you know, the ability to use a bundled version of pjproject was introduced with Asterisk 13.8.0. More info on the Asterisk Wiki <https://wiki.asterisk.org/wiki/display/AST/Building+and+Installing+pjproject#BuildingandInstallingpjproject-bundled> and in this email thread <http://lists.digium.com/pipermail/asterisk-users/2016-March/288685.html>. Since then I've fixed a few

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

Hi! I am still trying to clean the voice after procesing it with speex echo cancellation 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 ?

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

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

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

I am trying to build 1.2beta1. I downloaded the sources from http://downloads.us.xiph.org/releases/speex/speex-1.2beta1.tar.gz and tried compiling it under visual studio 2005. it gave the following errors: LIB : fatal error LNK1181: cannot open input file '.\debug_rtl_dll\medfilter.obj' Build log was saved at

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

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
