similar to: Bug in decoding

After searching 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

Looking better. Just make sure to remove the stuff that isn't C99-compatible (e.g. // comments). > I've

I submitted a version of testenc.c to this list MONTHS ago that fixed this problem. It uses a reconfigurable group delay. If you had given me cvs access I could've committed the changes myself. Anyway, the file is attached (again). Maybe this time you'll actually notice the email. Sorry if I seem a little short. It's just very annoying to put the time into learning and improving a

Hi Steve, thanks for the advice. I placed the appropriate functions outside the while statement but I still get this error at the while loop: First-chance exception at 0x004010fa in SPXDEC.exe: 0xC0000005: Access violation reading location 0x0000000c. Unhandled exception at 0x004010fa in SPXDEC.exe: 0xC0000005: Access violation reading location 0x0000000c. It looks like the same error. I've

Hi Jim, Actually, I don't see anything wrong with the internal structure having a different type than the interface, as long both types are big enough to hold the possible values (in this case 0 and 1). Though, as you pointed out, testenc needs to be fixed to use spx_int32_t instead of int. I'll change that. Jean-Marc Jim Crichton a ?crit : > st->highpass_enabled is typed

Hi All, We are using speex decoder only for narrow band decoding. Quite often, even though source frame is not silence, decoded audio is silence. I wonder there is a problem in the way we uses speex decoder API. Basically, we initialize speex decoder only once and just reset the decoder before we decoding another file. Do we need to intialize speex decoder and destory decoder for each audio file

I am wont to decode a speex 11kbps 8kHz 16bit to a raw data 8kHz 16bit LSB on a c5509. Trying to understand the "testenc-TI-C5x.c" exsample, but it looks to me wary complicated. Is there more documentation for the exsample or a decoder exsample available? Can somebody help? Peter -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hi, I am trying to develop a command line utility on PC side which will decode the encoded speex file without any header - ie. raw speex encoded data. I downloaded the speex-1.2rc1 version and used the testenc.c under libspeex library. Just to make sure that things are working fine, encoded a .raw audio file and could get the .bit and decoded audio raw file which was validated by using a raw to

Hi all, I'm new to the group. I'm looking at the speex code with an eye towards maybe helping out with either codec optimization or fixed-point implementation, The SNR calculation in testenc.c and testenc_uwb.c doesn't make sense to me. The code is { float enoise=0, esig=0, snr; for (i=0;i<FRAME_SIZE;i++) {

For clarity I attached modified testenc.c I used to test my code.

Hi I am using first time speex library, and this is my first problem. I need to decode AMR-NB packet to PCM. I read all manual instruction and I wrote these simple lines of code. bool CMMediaObj::AmrInit() { speex_bits_init(&bits); destate = speex_decoder_init(&speex_nb_mode); int tmp=1; speex_decoder_ctl(destate, SPEEX_SET_ENH,

Hi all, Please a moment to look my source code, this is very similar to example of the documentation. I added FIXED_POINT flag. My source code compile and build but not decode correctly (the error may be in the while). I work with eVC 4.0 and pocket pc 2003. Someone know what is the error? Thanks. Rodrigo. #include "speex.h" #define FRAME_SIZE 160 void CPlayerDlg::OnButton3() {

Hi, The manual 1.1.6 of sampledec.c says that /*Destroy the decoder state*/ speex_encoder_destroy(state); Should it be be /*Destroy the decoder state*/ speex_decoder_destroy(state); instead? -------------- next part -------------- An HTML attachment was scrubbed...

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

Dear Speex community, I am having problems to get the Speex Decoding API to work properly in our project. I am working in an embedded project with a very limited RAM and Flash memory and would like to use Speex encoded files to save memory while having good voice sounds in our speakers. I have developed a Windows-based tool to convert WAV files to Speex files in packets of 160 bytes (we are

Hi all, I have just started playing with speex, and come up with the following code, which just encode a frame of 160 shorts, and the decode it. For some reason the decoded sample is completely different than the original one. is my code wrong? If so what? Or is it a reasonable which depends of values that weren't correctly set? Thanks, Andre #include <stdio.h> #include

I haven't tested, but it looks sane. Just a few comments: - printf("\tERROR not enough bits left after wb\n"); this is actually now an error. It just means you got to the end of the

hey guys, I just compiled an application similar to sampledec.c (for speex 1.1.10) and it was fine but when I executed it, the app exited without doing anything. I'm using MS VC 6.0 and this was all I got - First-chance exception in sampledec.exe : 0xC0000005: Access Violation. Has anyone encountered this / does anyone know how to deal with it? by the way, sampleenc executed perfectly... When

I'm confused about the format of the PCM/WAV data for speex_encode & speex_decode speex_encode(enc_state, input_frame, &bits); In the manual, it says "input_frame is a (float *) pointing to the beginning of a speech frame" (for encode) But I've found that in speexenc.c and testenc.c, short* is used instead of float* So, isn't it signed 16 bit samples(if
