Sending speex over a network
Hi All,
I would like to communicate speech over a network compressed using speex.
However, I do not want to communicate a whole Ogg-formatted file. I am
interested in only the speech frames.
I invoked:
speexenc input-file-name - > raw-speech
This, I am thinking gives the speech frames only. To play this back at the
receiving end, do I need to format it into Ogg formatted file before I can

Encode and decode using speex
Hi,
I am new to speex and I am trying to use the sample program given in the
speex document.
I have made some modification to that sample, so that input can be read from
a file and the output can be re-directed to the file.
I tried to encode an audio file using the sampleenc and decode the same by
sampledec.c I am able to do it successfully, but when i try to play the
output file from the

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!

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?

Re: compatibility issues.
For a streaming application like VOIP, you collect 20 ms of samples, feed
this through the encoder, stick it in an RTP packet, and send if over the
network. On the receive side you feed packets through a jitter buffer to
the decoder, and then copy the output audio to your output device. Speex
runs efficiently on most compilers, so the real-time requirement is not a
big deal, as long as you

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

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

Windows Mobile 5.0 SDK - SPEEX
Hello
I've looked into SPEEX SDK and source codes provided on site www.speex.org , and I'm trying to include in my Visual Studio 2005 - Visual C++ SmartDevice WM 5.0 the facilities provided by SPEEX (both encoding/decoding).I've downloaded the header files (i.e. Speex.h Speex_bits.h etc) and also the libspeex.lib.After creating my encoding/decoding functions following the

Re: compatibility issues.
okay that questioned is answered, thank you.
I am interested in using speex in a VOIP application. do i need to put it in into
the ogg contianer format in order to encode/decode and send it? or will it work
"as is"? if the latter then:

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

Using speex on ARM7TDMI...
Hi,
I'm evaluating the libspeex library for usage in an embedded platform
based on an ARM7 TDMI micro (the ubiquitous Atmel AT91SAM7S).
In details, I'm trying to use libspeex to encode the audio stream
coming into the micro from an I2S channel and saving the encoded audio
to an SD card (currently in binary format just to test it decoded back
to the I2S channel from the saved file), but

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,

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

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,

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 sampledec.c -o dec -lspeex
I run these two program in this way and then speak loudly:

I thought I would hear my voice. However, what i heard was a lot of
