search for: speex_decoder_int

...ching the mailing list archive (I forgot to do that before posting, sorry!) I found the solutions: 1) The documentation has a mistake: The bit terminator is NOT set automatically! (I'm using the latest speex version!) It has to be set manually using speex_bits_insert_terminator(&bits); 2) speex_decoder_int() has to be called as long, as it returns -1. After that, all frames should be decoded. This should be added to the docu! Bugreport: I tried using speex_bits_remaining() instead of checking the return value of speex_decoder_int() but this leads to an endless loop! Or can't this function be use...

...degraded due to this. I investigated and found out that the same bug/error appears if I write a simple C-program. My main program was testenc.c in the speex source code. What I changed was to remove the decoder initialization in the beginning of the file and put them in the while()-loop before speex_decoder_int() and put a speex_decoder_destroy() just after the decode call (and of course, removed the destroy call at the end of the program). If I played the result from the original program, it was all clear and fine. With my multi decoding init and destroy function calls, the sound quality was reduced...

Hi Tom, Thanks for your reply, I'm having a few difficulty's following you advise. You mention that I should be calling 'speex_encoder_int' & 'speex_decoder_int', I'm having problems finding these functions in the speex header. I am currenlty calling speex_encoder_init & speex_decoder_init in my test code, I have repeated the relevent bits of the example bellow. My version of speex is 1.1.6. Thanks once again for your help, David....

Hi All, I'm very new to speex and in fact handling audio at all, it seems I have run in to a problem I seem unable to fix. I'm trying to take audio from a microphone using alsa, then encode it as speex and save to disk. I have been wondering if it has something to do with endian type, but speexenc and speexdec works fine. Currently I have the following setup: Platform:
