similar to: CELT on ARM?

Tony, How is this going? Have you been able to get CELT to run on a TI55xx? I am very interested in the % utilization of the hardware and whether multiple instance of CELT on the same DSP are feasible. I look forward to your findings.

Jean-Mark, Tim, Could either of you expound on the following comment in cwrs.c? /*If _k==0, the following do-while loop will overflow the buffer.*/ ---------------------------------------------------------------- ...because the following do-loop does overflow the buffer when k=126 k=2; do _u[k]=(k<<1)-1; while(++k<len); Thanks, MikeH -------------- next

Gents, "CELT now supports a larger dynamic range, suitable for encoding 24-bit audio (float version only)." I realize this was way back in V6, but is it still true?

I am trying to get CELT running on a TI 5515 and am having trouble creating a heap large enough to accommodate all of the dynamically created variables. In fact, I would much prefer to have all variables created statically. Could someone give me a short tutorial on what I need to do the create all of the requisite variable statically? Thx, MikeH -------------- next part -------------- An

Tim, et al, I have run into several problems with V0.8.0. I will address them seperately. 1. My compiler is complaining about the following code in celt.c which seems to define metric first as celt_word32, then as celt_word16. Am I mis-interpreting something? ?? VARDECL(celt_word32, metric); ?? ALLOC(metric, len, celt_word16); Thx MikeH -------------- next part -------------- An HTML attachment

"frame_size = PCM audio in signed 16-bit format (native endian). There must be exactly frame_size samples per channel." Sorry for such a simple request, but could you please clarify the definition of frame_size when using stereo audio channels? When you say "frame_size samples" does this mean that, if my frame_size is defined as 128, there are 64 left samples and 64 right

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.

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 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

Hi Jean-Marc, I got to this mailing list while trying to use the latest SPEEX version (1.2rc1) VAD capabilities. I had difficulties to successfully distinguish speech from non speech on recorded files (probably doing something wrong). Digging into the code I found out a remark saying :"*The VAD has been replaced by a hack pending a complete rewrite*". In search for answer I found out

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

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?

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

Hello everyone, For a private project I would like to make a new Internet Intercom device (for my kids and me). At the moment I use a separate DSP with Ogg/Vorbis (VS1053) but I like a challenge ;-) Is a eg. ST32F10x (cortex m3) or a new ST32F40x (cortex m4) powerful enough to do encoding and decoding ? Any existing projects to learn from? Thanks for your time, Edwin van den Oetelaar

I am attempting to port CELT to the TI C5515 DSP. I am compiling/assembling/linking with Code Composer Studio 4. I have enabled the TI_55 specific optimizations in my config.h file per this <http://lists.xiph.org/pipermail/celt-dev/2008-December/000033.html> post. However, I am getting several "undefined symbol" linking errors that do not make sense to me. According to the error
