Hello Guys
hello everybody in this great mailing list , i have some difficulties to follow my code .
i solved some problems thanks to Carine Liang , but i still have one problem and i think it is fatal one.
when i encode the voice data in a wav file it is decoded without any errors it gives me 84 bytes wav file size for 139 kbytes wav audio data .Naturally i wanted to return my file back to its normal

About reducing noise..
Hello,
When I decode a recoded sound encoded by speex, it has too much noise.
The noise is "slightly" reduced if I set the quality to 10. How do I get
rid of this noise? The code is as follows.
For encoding .
state = speex_encoder_init ( &speex_nb_mode );
tmp = 7;
speex_encoder_ctl ( state, SPEEX_SET_MODE, &tmp);
// set quality
tmp = 10;
speex_encoder_ctl ( state,

decode in ppc 2003
Hi,
My problem is at the second fread function,
fread(&nbBytes, sizeof(int), 1, fin); //the first fread
fread(cbits,1, nbBytes, fin);// the second fread.
When I'm debugging always nbytes is greater than cbits. This give me a
execution error.
Thanks.
Rodrigo.

just noise
Hi, I tried both the stable and beta versions of the speex source
code download on Mac OS 10.4.9. I just do:
./configure
make
sudo make install
Then I added libspeex.a from /usr/local/lib and the headers to my
xcode project. My app compiles and I'm able to call all of the speex
functions. I copied the example code from the website and tweaked it
to include the first 10000 bytes of

decode in ppc 2003
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.

You are writing to a test.wav file, but I don't see a RIFF header being written to this file.

Note that FIXED_POINT is only related to compiling speex, not your
application. Also, in 1.1.x, the output and output format for audio
changed to 'short' (instead of float).

Speex stereo encoding
Hi.
I trying to encode PCM16 8000Hz stereo data to speex and put it into the .flv file format. But at the output I can hear only noise. What I doing wrong? Here is the code:

SpeexBits bits;
void *enc_state;
int frame_size;
int quality = 10;
char cbits[MAX_FRAME_BYTES];
FILE *fin, *speex;

Audio file is corrupted after decoding
I successfully encoded and decoded a wav file of PCM 16 , MONO and with
sample rate 8000 in Android OS. The size of the original wav file and
decoded file is near.
But i am not able to play the decoded audio file, the mediaplayer says
that the file has been corrupted.

You should really do a check to make sure
nbBytes isn't larger than 200, otherwise you're going to read past the end
of your char array.
fread (&nbBytes, sizeof(int), 1, fo);

error in decoding raw speex file
Hi, Speex Fans,
I collected the speex raw file from flash server and tried to decode it with
samepldec.c ( I modified the code the file input) as below.
speex rate=8khz, one framesize=10 bytes in the client,
When I ran the decoding program, it kept displaying the error below and the
file genertaed is corrupt too.
Please help point out what is wrong. I also attach the raw speex file.
Thanks,

Please 30 second to look a my code
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

Error Executing sampledec in VC++
Mon,
Here is feedback that I got concerning the access violation, i.e. the failure of the while loop below. Does this solve the problem?
Steve
My guess is that speex_decoder_init() should be outside the while().. loop
as speex_decoder_destroy() is also outside.

Error Executing sampledec in VC++
hey guys, I just compiled an application similar to sampledec.c (for speex

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,
