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

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, We are testing CELT 0.7.1 on an iPod touch and it seems we are already reaching the CPU limit of the machine for a 1 channel both directions stream. The CELT README says that the code should be compiled with fixed-point support, but it it not clear how it has to be used later on. We currently use celt_encode_float/celt_decode_float functions. Can we still use them with the fixed point version

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.

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. I am glad to inform everyone here that support for decoding using libcelt was just pushed to ffmpeg. It raised a few API questions or issues: * At least while it's experimental, having a constant in the library for the supported bitstream version would probably be useful. Something like that comes to mind: extern celt_int32 celt_bitstream_version; or, even better: int

Hi, I'm using Celt version 0.7.1 in low complexity mode (i.e. no pitch information). In case a packet is lost i was planning to use the celt_decode_lost function. I realised though it uses pitch information inside. Does the celt_decode_lost function still works with no pitch information? Are there some changes to be done? Thanks Regards Riccardo Riccardo Micci Senior DSP Engineer,

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

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'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

Hi, In order to fit the decoder in memory in our embedded architecture we set the MAX_PERIOD #define equal to the frame size. This doesn't affect the code bit accuracy in normal decoding. The #define it's used celt_decode_lost function though. Is it possible to get celt_decode_lost to work with a value different from the default? Thanks Riccardo Riccardo Micci Senior DSP Engineer,

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

Is there a particular reason why CELT grabs 100KB of stack immediately? Is that really required or can that be trimmed down some/a lot? -a

Hi, I try to work with CELT encoder & decoder in 2 different threads at the same time. So I create/destroy encoder and encode in one thread and create/destroy decoder and decode in other thread. If I didn't protect celt_encoder_create, celt_encode_float and celt_decoder_create, celt_decode_float with CRITICAL_SECTION I get stable error in icwrs32 or ec_byte_write1 (more often) in encoder.

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
