similar to: can I create command line versions of the newer test releases?

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

I am working on a project that transports audio in realtime from a linux box to a windows box throuh libcelt. The windows client program is written in C# and C++ and I therefore need the celt library in its most recent version (0.7) to be able to compile in Visual Studio 2008. In order to do this I, as I understand it, need a .vcproj file for the project. Are there any plans on making such a

Problems building celt-0.5.2 for blackfin.

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

We were trying to normalize bands that didn't actually exist (e.g., the last band with 320-sample frames at 32kHz).

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 again, I was just looking at reviews on vorbis and reading some listening test results when I came across several web sites that were saying something about Vorbis quality -2. From what I read a few programs have Vorbis going down to quality -2 and I even think hydrogen audio forums mentions it in a speech compression topic. Does this quality really exist and has anyone even heard of it? I

I'd like to add support for CELT in a C# application. To do so, I'd like to build CELT as a static library using VS which I would then wrap with C++/CLI so I can access the encode/decode funtionality from within C#. Is it possible to compile CELT using Visual Studio? The first issue I ran into was that VS doesn't support the 'restrict' keyword. It does have __restrict which

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

Hi,I have been trying some different sample rate and bitrate combinations to get a feel for how CELT behaves,too, like Andrew Lentvorski. But I want to use VBR option.I want to ask a question about VBR in CELT codec.Can we use VBR option in CELT ??? "byte_per_packet" variable in code means constant bit rate, does not it ?In this code : bytes_per_packet is constant.len =

HiI'm trying to run CELT on Win32 but I'm running into some corrupted stack errors when using alloca(). When get_required_bits32() (in file cwrs.c:308) is called from get_required_bits() (in file cwrs.c:328) the 'K' parameter is 1 which means that the uint32 which is allocated on the stack only has 3 bytes instead of 4. This results in a corrupted stack in the following call to

Hi, compiling the latest release 0.5.1 (as well as from git) with gcc-4.2.4 on zenwalk (slackware current), ectest fails; using gcc-3.4.6 all tests succeeds. -------------- next part -------------- An HTML attachment was scrubbed...

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

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 all I have spent the last three days evaluating CELT on our supported platforms. I found a bug in quant_bands.c, that due to processor/compilation differences did not cause an issue on x86 platforms, but is a problem on the MIPS processor embedded devices. When decoding on the MIPS devices, there was a lot of noise added during the decoding, the noise is mainly in the 15 khz to 21 khz range.

Hi, my name is Raymond and I'm new to this list. While I think Vorbis sounds good with its "quality" settings, I have a few problems when I set the format to constrain the bitrate so it doesn't go any higher than 128KBPS, for example. This problem only occurs with stereo files, not mono. Let's say I set the format to use bitrates up to 45KBPS. Well, the low-pass filter has

Hi, I'm new here so an introduction. I'm Stefan de Konink, I have a diverse past, present and future in coding, content creation and a background in speech research. As introduced on #celt I want to do some promotion for the codec. I was positively surprised by the availability of something 'almost done' and totally usable in the form of celtclient.c, attached is a tiny
