I am currently using speex and ogg to archive voice data. The data comes in PCM ulaw at 8kHz and I use a table look up to convert it to normal 16-bit PCM data. Whenver the sound coming in is voice everything works perfectly. However, we periodically run test signals through our system to determine link problems.. etc. This test signal totally hoses speex during playback, but only when you try to

Well I think a sinusoid shouldn't totally trash the encoder state, so I still think theres a bug lurking around in there. The denoiser just prevents it from ever making it to the encoder. Just from browsing through the speex code and from what I've learned reading through the mailing list, it looks like there are a few places where checks are in place to prevent sinusoids from

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,

Hi -- I'm looking at adding Speex decoder and encoder support to the Miles Sound System, a commercial library used by game developers on various platforms including PCs, the Mac, and game consoles. As part of my initial evaluation, I've gone ahead and downloaded the 1.0.4 and 1.1.1 Win32 binary distributions and played around encoding and decoding various files with the speexenc.exe and

this is not really a development question, but i didn't find another mailing list to ask it. any idea why size of wav file doubles when it is encoded to speex and back to wav: $ ls -ls testi.wav 40 -rw-r--r-- 1 foo foo 40674 May 4 14:38 testi.wav $ speexenc --denoise --agc --quality 10 testi.wav testi.spx Encoding 8000 Hz audio using narrowband mode (mono) $ ls -ls testi.spx 20

Hi, I just started using speex recently and I've been having problem with Speex ver. 1.1.10 decoder. I used Speex to encode a wav file to spx then decode it back to wav file to see the voice quality that results from different speex options. Somehow, I couldn't get the original wav file back. I used both Speex ver 1.1.6 and ver 1.1.10 to both encode and decode, despite the same output

Thank you very much for your immediate attention! I've exported my wav files to raw files before encoding and the click is now gone. That sure beats discarding the last packet, which was the workaround "solution" I was going to implement...

Hello developers, I have a question about supported bitrates for SPEEX. Regardless of whether I specify a 10kbps or a 8kbps bitrate, the encoded .spx file is the same size and have the same PESQ value. This makes me wonder if SPEEX supports arbitrary bitrates, or only a certain set. A few more details about my configuration: I am using SPEEX encoder version 1.1.12 I am encoding a narrowband

I have successfully DECODED speex on TI C5509: #define TESTENC_BYTES_PER_FRAME 20 /* 8kbps */ #define TESTENC_QUALITY 4 /* 8kbps */ I am trying to generate the files I need with speexenc.exe: speexenc -n --quality 4 -V male.wav male.spx But I can't decode the files on C5x. Yes, I have seen that speexenc.exe adds Ogg header and

OK, that was a stupid error in the le_int prototype. It's fixed in svn now.

I am transcoding mp3 to wave using ffmpeg I am then piping it to speexenc for speex encoding but the speex file size is 496 bytes after the command ends https://lists.ubuntu.com/archives/ubuntu-users/2010-March/212927.html https://lists.ubuntu.com/archives/ubuntu-users/2010-March/212949.html https://lists.ubuntu.com/archives/ubuntu-users/2010-March/212954.html what am I doing wrong? bellow is

Hi, I just released unstable version 1.1.2 that contains more fixed-point work. Though it's still not 100% complete, enough have been done to make it run in real-time on ARM. In order to do that, compile with --enable-fixed-point --enable-arm-asm. All narrowband modes work in real-time with complexity 1 (some work with higher complexity) and some wideband modes also work (up to ~20 kbps) at

Hi, Just to let you know version 1.1.6 is out. Changes are: * Improved jitter buffer (now actually works!) * Denoiser tuning * Improved echo canceller (please send feedback) * Support for Symbian OS (thanks to Conrad Parker) * Gapless playback for speexenc/speexdec * Run-time identification of Speex version with a new speex_lib_ctl() call * Moved the includes to /usr/include/speex/ Jean-Marc
