similar to: how to use celt codec

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

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

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? If

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

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?

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.

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

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

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

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

hello celt developers. im just wondering if its possible to compile celt codec for windows? if so, could someone point me in the right direction? thanks.

Is it all right to discuss CELT here? I haven't seen any specific mailing list for it yet. I would like to ask if someone could provide me one or two sample Ogg CELT files, so I could test detection in ogginfo. I know CELT content isn't really supposed to be around as files since it would lose all the format's latency advantages, but I assume people can create them if need be. -Ivo

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

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 (

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

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

Hi Jean-Marc, I was just wondering if maybe you would consider a "blog-like" text file in the codebase where you just jot down your thoughts about why you are making a change, and where you think you are headed. For example, I noticed today that you completely removed the pitch prediction code. It would be nice to know if you did that because you're moving away from using it as

What is the best option for beginner to try Celt codec, i will try to test live audio from point a to point b. Is there any windows solution? Ekiga?
