Hi I am trying to evaluate the quality of the CELT codec by using the 0.8.0 testcelt tool to encode and decode the input. I want to test different bitrates and selected the below parameters for 64, 96, 128, 196, 256kB: ./celt-0.8.0/libcelt/testcelt.exe 44100 2 256 46 $1.sw $1-64kb.sw ./celt-0.8.0/libcelt/testcelt.exe 44100 2 192 46 $1.sw $1-96kb.sw ./celt-0.8.0/libcelt/testcelt.exe 44100 2 128

? There seems to be a memory violation when calling celt_mode_create(48000, 240). ? The function compute_pulse_cache() calls celt_alloc (the second one, bits=celt_alloc()) in order to allocate 343 byte, but it is using about 872 bytes at that location, which will be deleted by the following allocations. ? In this case the following encoder call crashes at first run. ? Sorry, my time is very

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

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

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, To enable stereo in celtenc do I need to change anything other than #define CHANNELS 1 to #define CHANNELS 2 The reason is after I do this the audio sounds distorted. Please let me know if I need to do anything else or whether I need to investigate what's happening at my end further. Paul.

Hi All, I'm looking to package up celt for inclusion in Fedora as the next stable release of ekiga/opal will have support for it. I've run into two issues in compiling it into a rpm. The first is a show stopper, then second one not so much of an issue but thought I'd report it for reference. The first issue is due to the celtdec and celtenc explicitly define rpath. I get the

Hi all, Just found out about this codec and I'm really impressed. I compiled celt-0.5.2.tar.gz on my desktop and tried out a few tests. I then did a native fixed point arm compile on my beagleboard which also worked a treat. Before I get started with the library I was trying to see if I could grab some real time audio, encode it and write to a file using arecord in conjunction with

Jean-Marc, It appears that since testcelt reads a WAVE file from disck and passes the data directly to celt_encode, so that celt_encode's "in" buffer must be expecting little-endian formatted packets. Is this correct? Is there endiness switch somewhere? Thx MikeH -------------- next part -------------- An HTML attachment was scrubbed... URL:

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

Hi, I am running celt 0.11.1 on my mac which is running osx lion. I invoke celt such as so: celtenc original.wav output.oga I do not see any files being encoded, the wave file is stereo 16 bit at 44.1kHz. Any ideas on why this is not working? I also tried the opus git repo for the latest sources, but that also does not produce an encoded file. Thanks -- -baeksanchang -------------- next

I have been trying some different sample rate and bitrate combinations to get a feel for how CELT behaves. I then encoded it with a couple of different frame sizes and sample rates. There were some small differences, but nothing horrible. So, I decided to run with 24KHz sample rate with 16 bit samples. This seemed like a reasonable tradeoff against the quality degradation that my folks

Hello everyone, I'm evaluating the Celt in terms of robustness against bit errors. So what I have done is encoding a wav file using the \tools\celtenc.exe and then manipulated the wav file according a desired bit error rate or burst error length. But the Celt decoder stops decoding with the first bit I manipulated even if this bit is not in the header. So is there a way to do the test

Is there are description somewhere of how CELT packs into the .oga file? Trying to reverse engineer it from the intertwined celtenc code is suboptimal. -a

Hi, I've recently successful built and run CELT under Windows using "testcelt.c" example file. Since I'm about to port it on a embedded platform i activated the FIXED_POINT #define. I included fixed_generic.h and without other changes to the code i tried to encode and decode the same file i previously used. The output though is completely saturated i.e. it jumps from -32768 to

Hi, I'm currently testing libcelt (celt-0.9.1) on my Openwrt/Kamikaze RDC-3210 platform and although I'm able to Crosscompile on my Ubuntu 10.10 machine without errors, the resulting celtenc doesn't seem to work properly. Ran ./configure via the Openwrt makefile first (activating fixed-point) ; I first produce a S16_LE Raw PCM file (48Khz, stereo) : test.pcm Then I try to encode

Dear all, Iam a student pursuing MSc degree in computer science at the University of Babylon,Iraq. My project is about the CELT. I have chosen version 0.3.2 of the software, lcc compiler, windows xp environment. One of my current problems is that when I execute the?testcelt program tool,?the output audio file can not be payed. Could you help me, please? I have tried some media players ,like

Hello list, I'm new here, and I'm experiencing problems with the latest snapshots of the CELT codec. In fact, starting from 0.11.0, everything compiles correctly, no error, but the software is unusable. I've always tested in a very "personal" way if everything went okay after installation : I use a very small PCM WAV file, and encode it with celtenc to stdout. If something
