CELT 0.5.0 is out
Hi Jean-Marc,
1. Why CELT versus Speex?
2. What's the RTP payload for CELT, so we can add it in Yate?
3. What are the SDP declaration parameters?

llcon software using CELT
Hi all,
I am the developer of the llcon software (llcon.sf.net) which is a
software making it possible for musicians to play in real-time over the
internet. Up to now I have used ADPCM or no audio coding.
Gregory Maxwell was pointing me to the great CELT project. Using CELT
has the advantage to be able to use higher sample rates, getting lower
code rate and better error concealment.

Force Opus/CELT to encode 2 mono instead of 1 stereo
Hi, folks,
I have an old CELT thing that I'm updating to Opus and I'm trying to get
individual pieces upgraded. My first task is upgrading the CELT encoder
to Opus.
The old CELT thing treated the L and R channels as independent mono
streams, encoded them somehow with CELT to form one bitstream, sent one
bitstream across, and then unpacked it manually after the decoder.
Can I do that

CELT 0.3.2, listening tests
Hello all,
This is slightly off-topic, but should be of interest to some people on
this list. I just released version 0.3.2 of the CELT ultra low-delay
audio codec (http://www.celt-codec.org/). CELT is designed to encode
high quality speech and music with less than 10 ms delay and at rates
starting from around 32 kbit/s.
This version is "special" in that it is the basis for some

how to use celt codec
hey great job with the celt codec. im very eager to use it. im just
wondering how? there is little to no documentation on how to use the celt
codec.
is there anyway to encode an icecast stream using the celt codec? or is
there any software with celt support built in? thanks.

CELT Test case failures
Hi ,
We've downloaded the CELTV0.11.1 source code from celt-codec.org . But
having trouble with mathops-test and tandem-test unit test that
exercises internal components of CELT codec, please find attached
document for each test case failure in details.
Also could you please give some inputs on CELT Low complexity code and
full version of the code, point me source code to CELT

CELT in Digital Radio Mondiale
Dear CELT Developers,
I wrote a proposal on how to integrate CELT into Digital Radio Mondiale (DRM+). The CELT codec has been integrated in the Spark transmission software and SoDiRa receiver software.
Please download the proposal here:

Suggestions and comments are welcome!

CELT 0.5.0 is out
Hi everyone,
I'm happy to announce CELT version 0.5.0. This release includes
simplifications to the bit allocation code and includes a new
low-complexity mode that can be enabled (without breaking compatibility)
on the encoder side. There are several other optimisations and bug fixes
included. The API has also been slightly modified, so code using CELT
will have to be updated (only minor

CELT/Opus Status Update
Hi everyone,
I've made several posts recently about CELT being "replaced" by the Opus
codec ( http://opus-codec.org/ ) and I thought it was time to give an
update on what's going on.
As many of you know, I've been involved at the IETF on this new Opus
codec, which essentially merge (a modified version of) Skype's SILK
codec with CELT. This is more than just two codecs

CELT for DAB broadcast radio
Hi all,
Just a quick note to let you know that we are currently integrating CELT
with our DAB transmission and reception software tools. We plan to have a
working demo at the broadcast conference IBC 2009 in September where we have
a small booth. We hope to be able to demonstrate a real-time DAB CELT
encoder as part our our Live CD based on Ubuntu and GNU/Radio (

Disable SILK/CELT only?
I saw the custom API, but nothing explicitly says "CELT-only" just
"custom sample rate and frame size".
I'll dig further now that you've pointed me in a direction.
Thanks,

CELT codec on TI C55x
Hello,
I am interested in using the CELT codec for an embedded
project around the DSP C55x family from TI.
Is this someone has already done?
Which is necessary to do that, which compiler, is there a specific
configuration ?
Is it necessary to have an Operating system to run the CELT codec ?
Is it possible to instantiate several times the CELT codec ?
Thank you in

CELT support for android
Hi All,
I am brand new to CELT and have some questions about support on android.
1) When I play the CELT samples at
http://www.celt-codec.org/samples/tasl/on my android Gingerbread
(2.3.4) phone it works - does it mean that Android
already has CELT built it? If yes, what version of the library is it using?
2) Is there any documentation I can refer to for support level on android?
- thanks

Disable SILK/CELT only?
Is there a configuration or compile flag that lets me disable the SILK
portion of the codec and use CELT only?
I could have sworn that there is something, but I can't seem to find it
in the mailing list archives.
The application here is that I am attempting to update from the old CELT
codec to OPUS. Unfortunately, the CELT codec was running *very* close
to the CPU (MIPS32--80MHz) limit

Using CELT on iPod
Hi,
We are testing CELT 0.7.1 on an iPod touch and it seems we are already reaching the CPU limit of the machine for a 1 channel both directions stream. The CELT README says that the code should be compiled with fixed-point support, but it it not clear how it has to be used later on. We currently use celt_encode_float/celt_decode_float functions. Can we still use them with the fixed point version
