AEC Troubles
Hello,
We are experiencing a few problems with Speex AEC. We are using it to
process audio data on a real time stream over IP with Speex codec (frame
size = 320).
We initialize the echo state like this :
SpeexEchoState * echo_state;
echo_state = speex_echo_state_init(320,512);
int sr = 16000;
speex_echo_ctl(echo_state, SPEEX_ECHO_SET_SAMPLING_RATE,&sr);
We are not really sure about

LIBCRYPTO?
Hi all,
I have a question about OpenSSH configuration. In Makefile there is defined
LIBS=$(LIBCRYPTO), but the problem is that the version of OpenSSL that I'm
using holds only the version LIBCRYPT. When adding LIBCRYPT to the Makefile
I get:
sshd.elf2flt: In function `key_regeneration_alarm':
/.../ssh/sshd.c:252: undefined reference to `RSA_free'
/.../ssh/sshd.c:253: undefined

[PATCH] fix -elf2flt usage for bfin-uclinux
There are multiple problems with the elf2flt usage in the configure script:
- clobbers LDFLAGS
- is used for all targets so breaks non-FLAT targets
- is only used for Blackfin FLAT targets

FW: SPEEX_PREPROCESS_GET_ECHO_STATE broken
All,
The implementation of SPEEX_PREPROCESS_GET_ECHO_STATE in preprocess.c seems to be broken. The value of the echo_state pointer is assigned to the stack variable rather than to the memory location pointed to by the stack variable.
Code snippet from preprocess.c:
case SPEEX_PREPROCESS_GET_ECHO_STATE:
ptr = (void*)st->echo_state;
break;
It seems as though the code should

Embedding samba...
Hi All,
I am working on a port of Samba to the uClinux/ColdFire system.
This is a port of Linux running on the Motorola ColdFire processors.
These processors have no MMU, so no virtual memory. It also means
that there is no true fork() call, only a vfork() type primitive
is supported. Other than this the fact that there is no MMU is
pretty transparent applications, it looks like any other Linux

Echo Canceller on Windows Mobile
Hi Jean Marc,
We are running the speex echo canceller code on a Windows Mobile smartphone using a TI OMAP 201MHz 850. We are making voip calls and audio is working without echo canceller code. Simply adding the following 2 functions whether the echo cancellation is wired in (ie we use the output frame ) or not performance becomes terrible. Note 2 separate threads are used to handle audio.

Echo canceller problem
Welcome everybody.
I am new here on the list. Thank you very much for speex encoder and decoder.
They are working great. I compile speex coded for str911 Arm processor.
But I have a big problem with echo canceller from 1.1.12 speex package.
I create echo canceler state:
SpeexEchoState * echo_state = speex_echo_state_init(FRAME_SIZE,
FRAME_SIZE * 5);
FRAME_SIZE is in my project 160 samples.

Hi, thanks. One question did you use these 2 functions

speex_echo_capture
No, I didn't use them. I use my own code to buffer microphone and speaker

Second part of data export patch
Hi,
Here are the next two patches for the data export.
speex_get_psd should be applied after speex_get_agc_gain (sent in previous
mail). It allows applications to get the power spectrum for the signal and
the noise estimate.
speex_get_prob should be applied last. It allows fetching the speech
probability of the current frame (the value that the _PROB_START and
_PROB_CONTINUE parameters are

2 weeks lost in the AEC world
Hi,
my VoIP system uses speex with framesize = 160 samples(20 ms) at 8khz,
sending and receiving paquets of 1600 samples(200 ms).
When I receive a packet, I buffered it (I have also tried with
speex_echo_playback) before sending to the speaker.
When I capture from microphone, I fist remove DC offset (I saw in OPAL
sources) and then I call speex_echo_cancellation for every one of the 10

Preprocessor Idle state
I'd like to maintain the speex preprocessor in an idle state when no
communication is needed. Purpose: keep the SpeexEchoState struct content
"frozen" as to restore last controlled cancel state for reuse with resumed
communication. Since the audio path to speaker and mic is intended to be
kept alive permanently, the echo delay should remain constant, a
prerequisite for

AEC frame size
?
hi all,
i am using the Acoustic Echo Cancellation from "Speex 1.1.12 version" in my VOIP application. Is it that the frame length to be chosen should always be 20ms or can i have flexibility in chosing the frame lenght?
on what parameters does the frame length choise depends?
thank you all,
Shri.

AEC learning behaviour
Hi,
I already implemented and posted a patch to do this serialization a few
weeks ago.
http://permalink.gmane.org/gmane.comp.audio.compression.speex.devel/6913
It is not integrated into the main git tree though.
Regards,
Simon

This is not part of the current API. It shouldn't be too hard add a
serialization routine for SpeexEchoState.

AEC in live performance
Hi,
I plan to use AEC for a live performance, storytelling for very young
children (and their parents!) in a mongolian yourte . Actually the
storyteller can make vocal loops, there is an omnidirectional microphone
in the center of the yourte, 5 loudspeakers in a circle along the
yourte's wall and Pure Data in a linux box. And now she wants to make
vocal loops over music and loops over
