similar to: Echo cancellor

what i want to achieve is simple, i want to be able to sitback in my chair and talk over a voip call using speex. as the mic and the speakers are built into the laptop, an echo canceller is required. what i am doing is this : First, each time i finish writing a block to the waveout, i copy it into a buffer like this: Segment *pseg = (Segment *)phead; waveOutUnprepareHeader(waveOut, phead,

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

A couple of things to be noted on the symbian port. 1. the spokn.mmp file is missing window.c, please add that. 2. smallft.c is not required. it has global data that prevents compilation on symbian. 3. lbr_48k_tabels.c has a global variable called dummy_epic_48k_variable on line 37. this has to be commneted out too. 4. check that all tables are declared const. i will shortly post the symbian

Why don't you just try it? From what others have been reporting, it shouldn't take you long to get it running. You can use speexenc and speexdec for testing.

I have sent the visual studio project files that compile the speex client to jean-marc directly (as an attachment), sometime this week, I will also upload the binary builds of static library files to my site www.phonestack.com. I am porting our LTP (lightweight telephony protocol) to some embedded systems. I require to run speex in an environment that doesn't support memory allocations. How

Hi, I found this message concerning VAD and was wondering whether VAD has been ported to fixed-point in the latest version?

Anybody knows if it's possible to disable zap echo cancellor from dialplan only for certain outbound calls ?? I share the same phone lines for voice calls and faxes. Iaxmodem works fine for me only turning off the echo cancellor, but I need it for voice calls. Any ideas ? maxx

ok, interesting ! Do you know how much CPU it takes for a real time encoding/decoding ? it's more around 20% or 80% instead ? Do you know if it works for 44100 Hz / 32kbps / Quality =8 ? thanks again.

Hi, I am experiencing some unfortunate problems when encoding WAV files to spx using version 1.0.4. A "click" which is not present in the original WAV file is added to the end of the spx file. Is this a known problem, and if so, which version of the encoder should I switch to... and if I have to switch the encoder, will I also have to switch the version of the decoder? Sincerely,

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

Speexdec plays ogg files. You can simply modify it to play your raw file or even rtp capture.

I can confirm that it will run in real time on iPhone if you compile with FIXED_POINT defined; it will also run in real time if you have FLOATING_POINT defined and disable 'Compile for Thumb' in the target's build settings in xcode. Wideband works too. Cheers, Dave

Can you provide me with a backtrace? It's quite hard to see what could happen. Also, can you reproduce the problem with testdenoise or only with your own code?
