similar to: Bug-fix release?

Hello list, We have recently introduced the codecs (optional) parameter on the Ogg media types for easier identification of encapsulated codecs in conditions were it's not feasable to examine the streams directly. I received a comment from the IESG that we should have some sort of list to describe how Ogg mapping strings translate to codec parameter strings, so I went ahead and compiled a

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?

Hello, There is a coodebook for the pitch gains stored in pgain_table.h. How can we get such a table? I have read in the CELT's paper that the codebook is trained, but I do not understand what that realy means. Can anyone give me an idea about that? Thank you very much. -------------- next part -------------- An HTML attachment was scrubbed... URL:

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

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

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

Hi guys, It looks to me like line 955 in celt.c should be: effectiveBytes = vbr_rate>>(3+BITRES); otherwise it seems like "effectiveBytes" is 8 times larger than it should be (at least if it's really meant to be bytes). Cheers, John Ridges

A small issue, but missing. Something like this would be helpful: - printf ("celtenc (CELT encoder)\n"); + printf ("celtenc (CELT %s encoder)\n", CELT_VERSION); til

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

Hi everyone, I've recently been making various changes to the way the modes work and the supported frame size. On new feature that may be of interest to some is that CELT should soon support changing the frame size dynamically within a stream. By that I mean varying the amount of audio (in time) transmitted at once, not the compressed size -- which has always been variable. That would

Hi, I am a newbe here, so I hope I am not asking something crazy. I was looking on the Celt downloads and I noticed that the latest command line builds were for version 0.6. I know it is still early in development, and that the devs probably don't have time for developing CL versions for everything. since I know nothing about sourcecode and whatnot, I was wondering if there was a fairly simple

Hi everyone, Version 0.5.2 has just been released with a few fixes over 0.5.1. On top of that, the pitch prediction was both improved and simplified. The other main change is a new bit allocation algorithm with better rounding and fine energy allocation. Have fun, Jean-Marc

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, I have noticed in the source code of CELT the numbers?like 2.f ,? 102.f? ,? 0.1f? ,? etc... What does the " f "? mean in this case? Is the number 102.f?? equal to the number 102 or the number 0.1f?? equal to the number? 0.1?! Thank you for your attention. Osama Y. Fadhil. -------------- next part -------------- An HTML attachment was scrubbed... URL:

In some conditions (sample rate, frame size, bytes per frame, audio data) the CELT allocator may run out of bits and attempt to place a negative number of pulses in a band. This causes an array underrun and other assorted nastyness. Patch attached. (It should also apply cleanly to 0.5.0 which is also impacted by this bug). -------------- next part -------------- A non-text attachment was
