file couldn't play after Speex encode and decode
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!

There is no such a thing as a "raw Speex format". Also, sampleenc.c and
sampledec.c are good for learning how to use the API, but the compressed
format shouldn't be used in

No, sampleenc/sampledec work on raw (headerless) files. Either you'll
need to work on raw files,

Error Executing sampledec in VC++
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...

Error Executing sampledec in VC++
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:

Re: Sending speex over a network
Hi All,
In sampleenc.c and sampledec.c, if I change the FRAME_SIZE to any other
value, I get very garbled speech. Can anyone tell me if I need to set
something else if I would like to change the frame size ?
Thanks

Noise problem while encoding and decoding
Hi, everyone!
I'm a newbie of speex develog. I tried to encode and decode with the
sample program in the speex manual. I compile those program with
gcc sampleenc.c -o enc -lspeex
gcc sampledec.c -o dec -lspeex
I run these two program in this way and then speak loudly:
./enc /dev/dsp ? ./dec /dev/dsp
I thought I would hear my voice. However, what i heard was a lot of
noise. I

How to use speex?
Hi,
I am a newcomer to speex.
When I use the sampleenc/sampledec programme to have a try of speex, the
encoded and decoded file can not be played in foobar.
But if I use the speexenc.exe/speexdec.exe in the Windows binary tools, the
encoded file can be played well.
Did I misuse something and can anyone provide a simple example for how to use
speex to build my own programme?

Raw files or Wav Files
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

decoded sample is completely differen from original one
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,

Integrating speex with VideoNet application: Constantbackground noise
Hi Jean-Marc,
Thanks. I've got the code for sampleenc and sampledec. But I didn't know how to verify whether the decoded file is correct.
So I tried to analyse the decoded output and compile with my input.
Test case: PCM samples, 8 bit, 8000 samples per sec.
When I pulled all my input to 0s, after encode and decode, the output fluctuates around -0.12 to 0.2 (in float), so when finally

Problems with stereo data
Hi all,
I have a problem when I am encoding (or decoding) stereo audio.
With mono data, things are fine and everything works without any problems.
When I try to decode stereo data, all I get is a static sound - similar to that of a radio not tuned to any specific station. I wonder what might be wrong?
Below is the code, first, of the encoder and next that of the decoder. Any information or

Speex Windows from 1.1.6 source
Hi All,
I am using Speex for encoding/decoding the audio stream for
my streaming application. I have used almost the same code
In the sampleenc.c and sampledec.c, except that I have used
The buffers from the mic as input for encoder and encoded audio
As input for decoder, instead of files input.
My Problem is the audio played on the receiving side after decoding

speex_nb_mode declaration problem

I am using the speex APIs in a gnuradio block.
I used the similar code as in the sampleenc.c/sampledec.c which works

My compilation does not give any error, but when I run the python test, it
complains that speex_nb_mode is undefined.
I tried to declare it explicitly then it as const SpeexMode *mode = NULL ,

The decoded voice is just noise and totally different from the original !
Hi all speex developers,
??? I have encoded 10 seconds buffer of Mic voice (raw) using speex on an embedded device, then transmitted it to a PC where i decoded the voice,in a way similar to the sampleenc.c and sampledec.c on website,
?BUT my problem is that the decoded voice is totally different from the original,what i hear is just noise !!
what is possible to be the reason ?
Any help is
