Gents, In Version 8.1, QCONST16 is defined as follows in arch.h within the FLOATING_POINT section: #define QCONST16(x,bits) (x) However, in both celt.c and quant_bands.c, QCONST16 is referenced without a conditional FLOATING_POINT define. So when I compile as FIXED_POINT I get an "undefined identifier" for QCONST16. Am I doing something wrong? Thx, MikeH

I realize this is ancient history, but I am trying to compile Ver 8.1 (from the download page) using Fixed Point and am getting compile errors as follows: argument of type "celt_sig *" is incompatible with parameter of type "celt_int16 *" libcelt81_orig_DSP/libcelt celt.c line 321 1304524612394 19769 argument of type "celt_sig *" is incompatible

Jean-Mark, Tim, Could either of you expound on the following comment in cwrs.c? /*If _k==0, the following do-while loop will overflow the buffer.*/ ---------------------------------------------------------------- ...because the following do-loop does overflow the buffer when k=126 k=2; do _u[k]=(k<<1)-1; while(++k<len); Thanks, MikeH -------------- next

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

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.

Tony, How is this going? Have you been able to get CELT to run on a TI55xx? I am very interested in the % utilization of the hardware and whether multiple instance of CELT on the same DSP are feasible. I look forward to your findings.

I am having trouble understanding the stack allocation scheme when using a C55xx device. From what I can tell, the GLOBAL_STACK_SIZE is set in arch.h to 100,000 bytes (when using FIXED_POINT), which is then used in the ALLOC_STACK macro found in stack_alloc.h. This macro seems to say, if global_stack==0, then call celt_alloc_scratch, found in os_support.h, which in turn attempts to allocate (using

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:

I am attempting to port CELT to the TI C5515 DSP. I am compiling/assembling/linking with Code Composer Studio 4. I have enabled the TI_55 specific optimizations in my config.h file per this <http://lists.xiph.org/pipermail/celt-dev/2008-December/000033.html> post. However, I am getting several "undefined symbol" linking errors that do not make sense to me. According to the error

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

Hi, In case it is of any help, to compile a static library for the iPhone, I had to add the following 2 lines in plc.c file : #include "arch.h" #include "stack_alloc.h" otherwise "celt_word16..." type are not defined and "VARDECL...." also not. Best Regards St?phane Letz

Anyone using asterisk with VoicePlus ? Looking for a new provider and wanted to get a little feedback

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

Gents, My TI C55xx complier is complaining about (in opus_encoder.c, opus_encode()): st->silk_mode.payloadSize_ms = 1000 * frame_size / st->Fs; where .payloadSize_ms is opus_int, frame_size is an int, and Fs is a long. Should one of these be cast differently? Thx, MikeH -------------- next part -------------- An HTML attachment was scrubbed... URL:

FYI there is a way to do 911 its called E-911 enhanced 911 the user has to set it up with the local emergency services to it and you setup your pbx to xmit the data. Here is the fcc rule about it http://www.fcc.gov/911/enhanced/

"frame_size = PCM audio in signed 16-bit format (native endian). There must be exactly frame_size samples per channel." Sorry for such a simple request, but could you please clarify the definition of frame_size when using stereo audio channels? When you say "frame_size samples" does this mean that, if my frame_size is defined as 128, there are 64 left samples and 64 right
