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

CELT 0.3.2, listening tests
Hi Jean Marc,
I was very impressed by the comparative results. Could you give a bit
more information about what really are 7kHz and 3.5kHz in the 48kHz table?
I am looking forward that this will bring a bigger separation between
the basic tools and speex in a sense that the basic tools could be used
with more than one codec. I even understand that there is interest in
the tools alone (Echo

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

Another paper on CELT
Hi,
For those interested in reading more on CELT, here's another paper that
just got accepted. That one focuses on the low-complexity mode and is
based on 0.5.1.

with Low Complexity and Very Low Delay, Accepted for EUSIPCO 2009.

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?

Possibility of Incorporating a psychoacoustic model in CELT
Good Morning;
Iam asking whether any one have knowledge about is it possiple to incorporate a
psycoacoustic model?(specifically?I mean ?MPEG-1 psychoacoustic model 1) into
the CELT codec(any version even older versions of the coder,?no matter) Iam
using version 0.3.2.
Kind Regards;
Osama.

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 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 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

Porting CELt to the C5505
Hi,
I am an applications engineer for Texas Instruments in the UK. I am trying to port the CELT codec to the C5505, this has HW accelerated FFT engine (http://focus.ti.com/docs/prod/folders/print/tms320vc5505.html).
I am having problems with the stack allocation. Do you have any reference code that compiles for the C55x under CCS (code composer studio)?

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

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

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 codec for red5phone
I'm wondering if anyone is familiar with red5 (flash media server) and the
phone application (http://code.google.com/p/red5phone/)
It's written in java. Red5phone already uses the codecs PCMU, PCMA, iLBC and
G.729. I'd like to see CELT added since it is open source and the best
quality codec out there. Would anyone know how to port the celt codec to
this application or to java?

CELT 0.10.0, upcoming bit-stream freeze, demo page
Hi,
This isn't that new anymore, but I'd let everyone know that CELT
0.10.0 is out. We've improved the quality quite a bit since the last
release and we fixed many bugs. For this release, Monty has written an
extensive demo page at:

Although it's not final yet, it contains a lot of information of CELT,

CELT 0.6.0 released, submitted as IETF draft
Hi everyone,
I'm pleased to announce version 0.6.0 of CELT, with many quality
improvements. This includes better stereo coupling, better handling of
transients, and better handling of highly tonal signals. In addition,
packet loss robustness has been improved through the optional use of
independent (intra) frames. CELT now supports a larger dynamic range,
suitable for encoding 24-bit audio

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.
I have
