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 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

22 kHz version of CELT
Hi, I'd like to know the reasons why CELT supports only signals with sampling frequency in the range of 32-96 kHz. In effect, it can clearly outperform speex at high bitrates, and has potential to be used in high quality voice communications even for 11, 16 and 22 kHz speech signals. It could also compete with SILK codec (to be soon released by Skype). See this page for more specifications

adding celt support to netjack some questions.
hi. i am currently adding celt support to netjack. very nice to see a free low-latency codec :) i currently dont require robustness against packet loss, because the sync code of netjack does not handle packet loss very gracefully. how much bandwidth is wasted for this feature ? is it sensible, to have the data downsampled berfore encoding , in order to reduce bandwidth ? i suspect that just

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 on ARM Cortex C3
Hello All. Could anybody help me with one question about CELT? I develop one project based on ARM7TDMI or Cortex C3 core. Can i use CELT with 32kHz and 48kB on these fixed point cores? Or it`s need to transfer project to Blackfin core (but it isn`t convenient to me)? With best regards, Alexey Voroshen.

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.

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. I have

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 0.10.0, 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: http://people.xiph.org/~xiphmont/demo/celt/demo.html Although it's not final yet, it contains a lot of information of CELT, recent changes and

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. -------------- next part -------------- An HTML attachment was scrubbed...

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: http://www.drm-sender.de/celt_in_drm.pdf Suggestions and comments are welcome! A live on-air DRM+ transmission using CELT (v.0.7.1) for audio encoding was

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 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.
