similar to: Opus on DAB

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 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 (

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 Thomas and Amit, Thanks for your notice and the detailed decode performance report. I describe the details of my encode/decode test on STM32F407ZG. A. opus version: latest 1.2.1 (TI: opus 1.1.2) B. KEIL 5.23 (TI: ARM compiler tool chain 5.2.7) C. setup the encoder as the below (fs is the sampling frequency) enc = opus_encoder_create(fs, chans, OPUS_APPLICATION_AUDIO, &opus_err);

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 I am not sure if this issue has been resolved, but on the latest opus 1.1.4, * I downloaded the tarball, * ran ./configure followed by * make and then * make check Can you please help? Thank you make[3]: Entering directory `/prj/avspw/karthikr/Development/BFamily/Broadcast/SDM845/Opus/opus-1.1.4/doc' doxygen Warning: ignoring unsupported tag

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

Hello everyone, I have been having trouble utilizing the PLC function (I think). In older versions (0.7.1) a pointer to NULL did the trick, but with code from the tip of the GIT repository, this method causes the codec to crash on the C55x fixed point platform. I have not determined where the crash occurs. I have also attempted to pass in an array of zero's and this creates an echoey, reverby

Hi everyone, After much waiting, Opus 1.1.1 is finally here. The main changes are: - x86 SSE, SSE2 and SSE4.1 optimizations contributed by Cisco, - MIPS optimizations contributed by Imagination Technologies, - ARM Neon optimizations contributed by Linaro and ARM, - many architecture-independent optimizations, - memory footprint reductions, and - several minor bug fixes. The quality of the

hi, I am porting opus encoder to a low end device with 32K ram, 256K flash and 32MHz arm M3 mcu. But opus seems consume too much. To make it work , what I can think of 1, Only fixed point supported 2, Only mono voice application supported 3, Set complexity to zero 4, Support only one sample rate, like 16KHz 5, Silk mode only or Celt mode only My question is , before

Hi I'm having a problem compiling opus-tools-0.1.7. Version opus-tools-0.1.6 seems to compile OK. I've tried with opus-1.0.3 and opus-1.1-beta. The errors are like this:- "undefined reference to `sqrtf'" etc. This OS is Peppermint Three, similar to Ubuntu 12.04. It uses:- gcc --version gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3 Google says it's maybe something to do

Hi, Since our device can only handle the Celt part of Opus (due to a MIPS limitation), we have two questions: 1. Is it possible to via SDP force the remote party to send a specific mode of the 32 different possible modes or to force the remote side to use CELT only? 2. In the reference implementation of Opus it looks like the only way to force the encoder to use CELT only

The opus code default compiles on -o2 optimization level. I would like to change it to -o3. I have tried doing the changes in makefile.unix . The change is not getting reflected. I am building the code in Code composer studio for TI processor C6000. Could anybody help me with this -------------- next part -------------- An HTML attachment was scrubbed... URL:

Xiph.Org is pleased to announce that we've released Opus 1.2. The 1.2 release includes: . Speech quality improvements especially in the 12-20 kbit/s range . Improved VBR encoding for hybrid mode . More aggressive use of wider speech bandwidth, including fullband speech starting at 14 kbit/s . Music quality improvements in the 32-48 kb/s range . Generic and SSE CELT optimizations .

Hello, samba v3.0.7 on suse linux v9.1 os/2 v4.x I have started the process of replacing our os/2 hosts with linux, starting with the server(s). Most of the problems have been firewall related, a topic only briefly discussed in the docs (nudge). Some of the hosts can now interact with the linux samba shares; not all though. I have run ip traces and have gotten to a point that is a

Hello all, after FOMS I decided to take a look at the opus library and I found that I could improve a bit the build system and cleanup the code a little bit. Most of the changes to the code has been suggested by my two tools cowstats and missingstatic (part of the ruby-elf gem if you care). HTH, Diego
