The encoded speex file should, by convention, be given the '.spx' extension rather than '.wav', but that is not the issue. What appears to be happening is that the '.wav' extension on your named output file from speexdec is not being recognised as '.wav' and, consequently, the file is being written as 'raw' data without the wave file header. I am not sure

Dear Jean-Marc and Peter: Thank you both very much for your time and advice. I did not realize that Lame MP3 code has a -r option (without reading its code). I have tried the suggested command lines verbatim with the added -r option, along with other combination of option settings. I could not figure out how to eliminate the distortion in the result, like voice turning either high or low

iam using speex for the first time...iam using it in real time.....in command line as:- speexenc /dev/dsp old.spx Encoding 8000 Hz audio using narrowband mode (mono) when i played this encoded file old.spx in command line:- aplay pld.spx Playing raw data 'old.spx' : Unsigned 8 bit, Rate 8000 Hz, Mono then i decoded this old.spx in command line:- speexdec old.spx new.wav Decoding 8000

I downloaded speex-1.2beta3-win32 binaries, and used the speexenc.exe and speexdec to process the file male.wav download from http://speex.org/samples I used both the narrowband and ultra-wideband mode: >speexenc -n --quality 3 male.wav n3.spx Encoding 8000 Hz audio using narrowband mode (mono) >speexdec n3.spx n3.wav Decoding 8000 Hz audio using narrowband mode (mono) Encoded with Speex

Well, you seem to be using FRAME_SIZE but only defining frame_size. Otherwise, the code looks OK, but it's always hard to tell. I suggest you start from speexenc/speexdec or from the example I wrote in the manual at: http://www.speex.org/manual/node12.html Jean-Marc Le ven 19/12/2003 à 05:22, Fabio a écrit : > Hi > i'm developing a sort of VoIP application > for my

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 all, I've another trivial request: Is there any particular reason why speexenc and speexdec return 1 on successful completion? It would be preferable if they returned 0 unless there were errors, to be consistent with other *nix utilities and to allow for easier scripting (eg speexdec sample.spx && cp sample.spx somewhere) Would anyone be against this? TIA, Bernard. --

Dear Speex codec community: I am working on conversion of voice files. I could not figure out how to use speexdec.exe 1.2.3 in piped mode in order to avoid the creation of the potentially large intermediate *.wav or *.pcm files. Any pointer to web or file of instruction is appreciated. Attempt (one long command line, failed): type d:\test.spx | "d:\speex 1.2.3\bin\speexdec.exe" - -

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

hi, i am using AVTransmit3.java for transmitting audio, how can i implement JSpeex or speex for compression and encoding. please give me some idea about this. shankar.s speex-dev-request@xiph.org wrote: Send Speex-dev mailing list submissions to speex-dev@xiph.org To subscribe or unsubscribe via the World Wide Web, visit http://lists.xiph.org/mailman/listinfo/speex-dev or, via email, send a

hi all, thanks Jean for the codec. I am new to speech coding. Am interested to implement speex on a TI dsp, say C54. just downloaded speex v 1.1.6. when I removed optimisation flags for win32 in libspeex.dsp, I get a slightly different output for decoding using speexdec.exe (debug version). no prob for speexenc.exe except for some differences in the ogg header. for anyone interested, i

Can you post the input and output file on the web and specify what options you're using (use speexenc/speexdec, *not* your own code).

Hi folks, I'm having trouble building the 'speexdec' executable in the win32 port of Speex. I'm using MSVC++ 6.0 on both a Win2000 and a WinXP box (the error occurs on both machines).
