[Interopcast-general] about translatingdocumentation, but not only documentation.
Just a few weeks ago, I was thinking of writing a streaming source using
libshout and portaudio. I was also considering LADSPA support, to do
some minor post-processing before encoding. However, I'm currently
developing on Mac OS X, and LADSPA's shared library plugin model has
some issues here to be resolved.
Another nice feature I have given a thought on is incorporating

speex_echo_cancel, please help!
Hello,
Need some help using the speex_echo_cancel.
I've read the documentation about the
speex_echo_cancellation function:
speex_echo_cancellation(echo_state, input_frame, echo_frame,
output_frame);
(in) echo_state => speex internal state.
(in) input_frame => audio captured by mic.
(in) echo_frame => the signal that was played in the
speaker.

Cross Platform Audio Library
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi all,
I was wondering if anyone had any advice on an audio library that is
better suited to be paired with Celt in terms of latency. I'm working
on an application that I would like to have running on both
windows/Linux systems. I started by using the OpenAL library but I have
run into an issue when feeding OpenAL small mono sample sizes that

[ Compile error in CVS, entry for a FAQ somewhere, place for test/comparison files to be uploaded?]
>Also, 'portaudio' doesn't appear to produce a static library at all, so it
doesn't appear to be possible to get a working splayer executable on Linux
unless there is a 'hidden' way to get the portaudio distribution to build one.
("ldd: -lportaudio not found").
I believe splayer is only intended to be a Win32 executable. Note that it is in a directory

Echo canceller
I am using 'portaudio' and 'speex' to implement a speech audio
capture/playback.
Preprocess works fine but not the echo canceller (associated with
preprocessor).
I have read 'testecho.c' but it didn't help me.
What I am doing bad? This is my implementation:

IceS output to alsa sound card
Hi Guys,
I'd reflect Vieri's question actually, because there must be a way of
doing it? Maybe not with ICES, but maybe combines with JackIT?
The reason for my interest is I work in a radio station in Spain, and
because of the geographics where I am we have to relay around a lot.
If there is a way of sending an incoming feed into ICES, and sending
it out in various directions, would

IceS output to alsa sound card
Hi.
I'm new to icecast.
I can see that IceS can source an input MIC, for example, from a sound card.
Can it also output a playlist to a sound card (to the speakers)?
If so, how?
Thanks

Re: compatibility issues.
Hi,
For the openSpeak project we use PortAudio V19 & speex. So if you
want some code examples, you can look an pick in our SVN (its GPL).
ATM we are having some problems with PortAudio v19 (it might still be
buggy somehow, it seems not to support the 32-kHz sampling rate used
by speex ultra-wide-band mode) so if you want something stable you'd
better use v18. And of course, if you

Echocancellation on windows
Hi all,
does anybody has ran echocancellation successfully on windows ?
I have a problem playing audio there. If you play a wav file no mater
how I play it after comparing the captured data with the original file
there is always
difference in the audio length (for 18 sec of audio there is more than
250 ms of difference). Which of course breaks echocancellation.

Asterisk now available with bundled pjproject!
The current Asterisk 13 and master git branches have a new feature that
will be included in 13.8.0: The ability to compile and run Asterisk with a
bundled version of pjproject.

Why would you want to do this? Several reasons:

Ogg Theora files player
Hello,
I try to compile player_example.c from http://downloads.xiph.org/releases/theora/libtheora-1.1.1.zip in Visual Studio 2008 on Windows XP.
I built and added to the project libogg-1.3.0, libtheora-1.1.1, libvorbis-1.3.2 (http://www.xiph.org/downloads/) and SDL-1.2.15 (http://www.libsdl.org/release/SDL-devel-1.2.15-VC.zip).

player_example vs splayer
Speaking of portability and people more familiar with SDL:
The reason we have two example players for theora is that monty wrote
the original example around the OSS audio interface used on several free
unix-like operating systems, which immediately excludes win32 and MacOS,
even though it used SDL to display the frames. SDL also has audio
support, and is quite widely ported.

Announcing IAXCLIENT v0.02 A cross-platform IAX client.
Asterisk-people,
Some of you may have heard that we were working on a simple,
cross-platform IAX client library called "iaxclient".
We've pretty much been "on vacation" with the project for a while,
but recently have made some progress, and now have the library working
across platforms, and a simple test client called "testcall", up and
