Did you make sure it really *sets* and not just return an incorrect
result?

preprocessor VAD only rocognize between silence and not silence
Hello,
in my project im using speex 1.2rc1 and the preprocessor VAD seems to
only separate complete silence from not complete silence frames.
The Speex Manual, you can read "The voice activity detector (VAD)
provided by the preprocessor is more advanced than the one directly
provided in the codec."
but if you go to the source code in preprocess.c line 995 "/* FIXME:

encoding speex, (insanity looming)
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:

[SPAM] [BombData][alltestmode] Re: Speex Echo Cancellation
As for me - speex_echo_cancellation is a better choise. Try using it in
capture thread instead
of those speex_echo_capture and speex_echo_playback functions.
And please, describe your problem in details. Cause the fact that you
"didn get echo cancellation"
doesn't mean you are doing smth wrong.

Win CE playback error
Hi,
I have a module sampling raw PCM data on Win CE as 10ms time slice (160 bytes), mono, 8000HZ, 16 bits per sample.
Does anyone know what is the mflops for using fixed point on a Win CE compared to using floating point?
Looking at the manual,
"In practice, frame_size will correspond to 20 ms when using 8, 16, or 32 kHz sampling
rate."
for a 8 kHz sampling, the framesize should be

problem: The decoded frame is not as the original one
Hi All,
i need your help in determining the problem in the following sample code (taken from speex manual) for fixed point encoding.
i tested encoding a 160 sample frame and then decoding it back But The problem is that the decoded frame is totally different from the original frame(see output below).What is the possible reason for this?.thanks for any help

Is SPEEX_GET_QUALITY implemented ?
Hi All,
Almost all my question is in the subject. I have written the
following small program and I get an error message when I try to use
SPEEX_GET_QUALITY. This functionality seems not to be used in speexenc.c
or speexdec.c.
I would appreciate any hints.
best regards,

Speex and DS
Thank you for the quick response Thorvald, but I think that's not the
problem here :[
I know how to capture the buffer and how to play it in the output buffer of
the DS.
The problem is (probably) with same kind of short/floats/bytes error in
conversion/copying
that the coder doesn't get.
I can have my buffer locked during the compression, it not the problem at
the moment.

Re: High pitched whine with Speex
When I just copy the microphone input buffer to the output buffer the
sound plays OK. But if I encode and decode the buffer through Speex I
get a high pitched constant tone in the background. I actually do hear
my voice speaking when I talk, but it's faint and much quieter than the
tone.
Here's what my data looks like:
Input is the first 5 floats of each input buffer.

speex_encode_int performance iphone4 + iOS5
Hi,I'm having performance issues encoding with speex on an iphone4 + iOS5. The same code yields excellent results on iPad2 + iOS5, Mac OS X 10.6 as well as Windows 7. The call to speex_encode_int is takes 0.0065 to complete. Because encoding is so latent the receiver incurs underruns.
Here is my speex setup:

I've targeted Speex to run under eCos with Thumb interworking using

I'd written a small test case to verifiy the operation:

encoding -> decoding doesnt work
hi all,
i'm new to speex and i'm stuck on a problem. I have a buffer that holds 5
seconds of audio data, sampled at 16000 hz and quantitized with 16 bits pcm.
I only want to encode it with speex and then decode it and write it back in
the same buffer.
no compiling errors and no errors during runtime, but from the sample of 5
seconds only a short noise is all I get.

LIB usage
Hello,
I'm trying to use the speexlib but I just can't do it. I've made just like the
example (on the site) says. Some times I get SIGFAULT. Also, I'm reading the
input_frames from /dev/dsp (directly). What is missing here?
speex_bits_init(&bits);
enc_state = speex_encoder_init(&speex_nb_mode);

Size of each block in a circular buffer and the sample rate
int frameSize;
speex_encoder_ctl(enc_state, SPEEX_GET_FRAME_SIZE, &frameSize);
Is frameSize in bytes? If not, what unit is it in? I need to know so I
know how big to make each element in my circular buffer.
Also, do I need to call
speex_encoder_ctl( enc_state, SPEEX_SET_SAMPLING_RATE, &sampleRate );
Depending on sample rate I record my audio in? If not, is there any
benefit to

Invalid mode encountered: corrupted stream?
Hi,
in my application i quite often (not allways) get those two warning:
"Invalid mode encountered: corrupted stream?"
"Invalid wideband mode encountered: corrupted stream?"
The stream is not corrupted but i wish to know what those warning mean to
correct my code.
My encode and decode routines are those (libspeex 1.1.4):

preprocessor VAD only rocognize between silence andnot silence
Jesus,
Unfortunately, FFT and magic algorithms don't work (yet?). You
might want to try this if you're not satisfied with Speex VAD:
http://lists.xiph.org/pipermail/speex-dev/2008-August/006860.html
It won't perform any miracles, but I think it works pretty well
and is easy to tweak.

Integrating speex with VideoNet application: Constantbackground noise
Hi John,
Thanks for your reply.
Yes, my output device is in 8-bit mode, same as my input mode. I'm actually working in char (8 bit) arrays. Is it necessary to work in signed short integers only? I changed all the short arrays in the example to char.

how to improve the voice quality (run speex on ADSP-BF533)
I bought a ADSP-BF533-EZkit-LITE V2.1 to develop a speech codec application using SPEEX. I have tested SpeexEcho project from both BlackfinSDK-Rel201 and BlackfinSDK-Rel310.
When disabling SPEEX processing, i.e. using PASS-THROUGH mode, the output voice is ok, which is exactly as the input voice. However, when enabling SPEEX processing, the output is bad, no matter how to set the parameters in

here is my speex encoder/decoder .. the sampleRate i use is 16000 and

can someone take a look in to the code and see if there is something that is
making that robot voice
