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

These were used because the entropy coder originally came from outside libcelt, and thus did not have a common type system. It's now undergone enough modification that it's not ever likely to be used as-is in another codec without some porting effort, so there's no real reason to maintain the typedefs separately. Hopefully we'll replace these all again somedate with a common set

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

When I removed the special case for EC_ILOG(0) in commit 06390d082dcdfa8addb3dde337543bc0f0ebae44, it broke ec_dec_uint() with _ft=1 (which should encode the value 0 using 0 bits). This feature was tested by ectest.c, but not actually used by libcelt. An assert has been added to ec_dec_uint() to ensure that we don't try to use this feature by accident. ec_enc_uint() was actually correct,

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

Hello, I'm building packages for Slackware and I've just tried to upgrade Slackware 13.37's CELT package to version 0.11.3, which apparently was released last year, but I've omitted it because it was not announced on the site. Anyway, now that I try build with the following configuration in my SlackBuild script: CFLAGS=$SLKCFLAGS -O2 \ CXXFLAGS=$SLKCFLAGS -O2 \

Hi, I am facing problem when using CELT for iPad. I wonder if someone have experience with that, or someone have idea why it happened. I was able to compile libCelt (and lib Ogg) for iPad (iOS 4.2) and for iPad Simulator I added those libraries to my application, and it was successfully compiled and linked, but once the application start it immediately crash (even if I am not using any of the

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 everyone, I'm pleased to announce that the IETF has just approved for Opus to become a standard. I'll still take a few more weeks of editing before it's published as an RFC, at which point we'll release version 1.0. From now on, we'll be replacing the use of the CELT name with Opus and I'd like to encourage everyone to switch to Opus in their applications. Note that

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

Hi everyone, I've just changed the API for CELT, but at least there's a good reason for that. It's now possible to use the same mode data for both mono and stereo. So here's the change: - The celt_mode_create() function has a "channels" parameter - The celt_encode_create() and celt_decoder_create() functions now have an additional "channels" parameter. - I

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

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

looking at the code for celt_encoder_ctl in 0.7.1 I'm confused as to why Complexity is described as a value from 0-10, but the code only appears to have one setting for 0-2 and another setting for 3-10. Is that for future use or am I missing something? case CELT_SET_COMPLEXITY_REQUEST: { int value = va_arg(ap, celt_int32); if (value<0 || value>10) goto bad_arg; if (value<=2) {
