opus multi-channel compress
Hello everyone,
I tried to compress audio with opus recently, which works fine on mono and stereo data .
But I want to compress 6 channels pcm with opus, I have not found an interface that compresses multi-channels.
1、Is there a multi-channel compression interface?
If so, where is it, and how can I call it?
If it doesn't exist, how can I modify it to make it support 6 channels?

Conversion API for computer telephony systems (Dialogic Mu-law wa v format to PCM encoded wav format)
I am working on a project involving the conversion of a Mu-law sound format
(Dialogic Mu-law wav format) file into a standard PCM encoded wav file
format.
Could somebody tell me if this feature is supported in the Vorbis software
and if there is any source code available that performs this task.
If not, does anybody know of any resources that might provide me with this
tools or information.

What is the format of the PCM/WAV data for speex_encode & speex_decode?
Speex 1.0.3 uses floats, but the unstable version 1.1.x uses short.

First, I'd like to ak why you want to use 1.1.4. If you don't need the
new features (fixed-point or preprocessor), you should probably stick to
1.0.3, which has received more testing. If you choose to use 1.1.4, you
need to send shorts to

from Adobe Flex / Flash Player 10 .flv Speex via Red5 to .wav PCM?
I am having trouble converting a .flv file uploaded from Adobe Flex /
Flash Player 10 to a Red5 server using the speex coder:
http://livedocs.adobe.com/flex/3/langref/flash/media/Microphone.html
http://jira.red5.org/confluence/display/codecs/Speex+Codec
Questions:
1. How do I extract the audio track out of such a .flv file?
2. How do I convert it from Speex to .wav PCM?
Thanks.

What is the format of the PCM/WAV data forspeex_encode & speex_decode?
Ok, I'm using 1.1.4, so I should pass signed short(wav data) directly to
speex_encode()?
But the samplecode that comes with 1.1.4 shows me to put short in float
array, and pass the float array to speex_encode()

What is the format of the PCM/WAV data for speex_encode & speex_decode?
I'm confused about the format of the PCM/WAV data for speex_encode &
speex_decode
speex_encode(enc_state, input_frame, &bits);
In the manual, it says "input_frame is a (float *) pointing to the beginning
of a speech frame" (for encode)
But I've found that in speexenc.c and testenc.c, short* is used instead of
float*
So, isn't it signed 16 bit samples(if

What is the format of the PCM/WAV dataforspeex_encode & speex_decode?
I thought it would be more update/better/faster, any thing wrong?
In the future, would you use short, and forget about float?
If so, I use 1.1.4, I wouldn't need to change my code in the future, right?
You said, it's unstable, yes, I got compiling errors with MsVC6 and MsVC.net
And I modified it a bit to get it compiled. Should I post the errors here?

[1.4 + FreeBSD 6.2] Playing WAV PCM file?
Hello
Happy New Year! I succesfully installed the Ports of Zaptel BSD 1.4.0
and Asterisk 1.4.13 (that's the latest in the Ports). To save CPU, I'd
like to play PCM WAV files instead of eg. GSM. Per...
www.voip-info.org/wiki/view/Convert+WAV+audio+files+for+use+in+Asterisk
... I recorded a sample of my voice using XP's Sound Recorder, then
ran the following :

compiling ffmpeg with --enable-libspeex (was Re: from Adobe Flex / Flash Player 10 .flv Speex via Red5 to .wav PCM?)
This is resolved:
apt-get remove libspeex-dev
cd ~/src/speex-1.2rc1/
./configure --prefix=/usr
make; make install
cd ../ffmpeg
./configure --enable-libspeex
make; make install
worked; then I was able to decode a Speex .flv file:
~/flvs$ ffmpeg -i SpeexQ6R16Efalse.flv foo.wav

You mean --print-after-all ? I don't see any way to pass that to lld; The debug info is fine when using llc.

ogg_sync_state with interleaved logical streams
Hi all,
I'm mixing logical streams at the page level. One stream has vorbis
data, the other has my own data. Do I need two ogg_sync_states or just
one?
Thanks,
Martin

[nbdkit PATCH 1/4] errors: Avoid interleaved errors from parallel threads
Since we construct our error/debug messages via multiple calls
to stdio primitives, we are at risk of multiple threads interleaving
their output if they try to output at once. Add a mutex to group
related outputs into an atomic chunk.

I think interleaved is the obvious choice - that's what most audio
applications are used to dealing with, it's what we need to feed to
audio hardware in the end usually, etc.

One advantage of storing in the MSB's is that the relative value remains
correct when processed as the larger word size. For instance, a signed
12 bit integer would use 0x400 to represent +50% amplitude. By

overlapping/interleaved histogram help
NOTE: I have read the FAQ, Verzani's book, Rtips, and googled.
For various reasons I don't want to use a density plot when comparing
two distributions, I would prefer to have interleaved histograms over
the same ranges.
In addition to this, I would also like to normalize the two histograms
so that both of their max Y values are the same (so I can compare
relative distributions within
