similar to: decode wav file sounds noise but no when play the encode file

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

I suggest that you write the command line as Jean-Marc suggested: speexenc sample.wav - | speexdec - sample_out.wav I have tested this and it works as expected. You need to specify the '-' for stdin and also for stdout. John As an aside, I notice that the wave output from speexdec does not write the wave file header when the output is destined for stdout. I believe this is incorrect

Dear sir, I've a problem that the .wav file couldn't play after calling "sampleenc male.wav|sampledec male_speex_15.wav".I found that the new file male_speex_15.wav is smaller than the original file in size.I implemented the test on Linux system.The original file male.wav is 96044 bytes,while the new file male_speex_15.wav is 96000 bytes.I'm eager to know the reason.Thankyou!

Hi, I had a similar question ... is the endian-ness of the encoded speex file, system dependent? or is it always little endian? If it's always little endian (like the header seems to be) then big endian machines (or java) will need to map everything to bigendian before decoding ... thanks in advance, Kaveh. <p>Ben Stanley wrote: > Hi, > > I got my hands on the LCA

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 Owen, I have little time right now to look at the details, but it would help if you could test with all 1.1.x versions and see when the problem appeared. Also, compile with --enable-fixed-point-debug so messages will be printed in case of overflows. Jean-Marc P.S. Please also post the original file.

Hi, I got my hands on the LCA 2003 CD today and I tried to listen to it on my powerbook running Linux. Instead of getting speech, I got an earfull of noise! Attempting the same experiment on an i386 with the same CD produced understandable speech. It seems that the output routine in speexdec converts the output data to little endian short format, which is incorrect on the ppc architecture. The

It seems that with the file I posted, the decode noise persists all the way back to 1.1.1, when using --enable-fixed-point. When we configure with --enable-fixed-point-debug, the decode seems to be correct, even on 1.1.6. Hope this helps, and thanks for your time!

This is resolved: apt-get remove libspeex-dev cd ~/src/speex-1.2rc1/ ./configure --prefix=/usr make; make install cd ../ffmpeg ./configure --enable-libspeex make; make install worked; then I was able to decode a Speex .flv file: ~/flvs$ ffmpeg -i SpeexQ6R16Efalse.flv foo.wav FFmpeg version SVN-r17174, Copyright (c) 2000-2009 Fabrice Bellard, et al. configuration: --enable-libspeex

Hi, I've recently set Asterisk up, 1.0.2 version. With 1 x X100P card and 1 SIP phone. I've noticed some horrible buzz/rasping type of sounds! These seem to occur when * is trying to play back some audio or sound to me? E.g. If I have an exten rule which plays one of the music on hold files when I dial 800 lets say, I get a really loud buzz for about 2 seconds and then the music plays.

Hello All, I have recently started working on SPEEX and thanks to the nice tutorial and examples, i was able to encode/decode files as per the command line programs speexenc.c and speexdec.c I tried the sampleenc/sampledec but, i know its only for the raw data. My question is what kind of raw data should be used to test them? Also, is it possible for me to use speex without any of the headers but

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

wow, the attitude wasn't necessary. What I was asking wasn't in the documentation, how am I supposed to know I wasn't supposed to initialize the encoder/decoder every time (I was trying to save space for the allocs), I've never dealt with codecs before and it isn't in the documentation. I was not insinuating that your code was wrong, I was hoping you could tell me that I set
