<speex-dev at xiph.org> Hi all, I'm a begginer with DSP and i need your help and suggestions. I'm trying to use the Speex and a DSP DM642 to implement a solution with voice! I'm using the 1.2 beta 3 distribution and the TI's Code Composer Studio v3.1 simulator. I coosed speex_C64_test.pjt and modified the speex_C64_test.cmd to only use the DM642 external RAM memory. I'm not sure about the input file, the speex file and the output file formats. The README file refers that the input file is a headerless 16-bit stereo audio file, derived from the male.wav test file ( http://www...

...ported the same 4kbps code to use on the ARM926 (GPP) side of the DaVinci, it sounds fine (no robotic artifacts). So this leads me to think somehow the Speex code is not working properly for 4kbps (and lower) on the DSP C64+ processor side (6kbps sounds good as mentioned above). I followed the ti speex_C64_test trunk example packaged with the Speex code; I used the example config.h and Makefile for my build. Am I doing something wrong with the compilation of the Speex code for the DSP C64+? I tried changing the complexity to 10 and turning on perceptual enhancement and it still sounds robotic; again, l...

Hi, I've been trying to get Speex to compile and run on the DSP of TI's new DaVinci System-On-Chip processor, which has both an ARM (ARM926) and a DSP (C64+, based on the C6400). I used the latest code (1.2beta) and followed the example in the speex- 1.2beta1/ti/speex_C64_test trunk to build the Speex library for the DSP. Basically I have a loopback application on the ARM that samples 8kHz 16-bit mono frames, gives them to the DSP to encode and decode them, and play the resulting decoded frames on the headphone. It seems to work but I get a clicking noise. I have veri...

I started my project using the CodeComposerStudio speex_C64_test.pjt in speex 1.1.11.1. To build using floating point, I created a new project with the same files and modified ti\config.h to #undef FIXED_POINT. Is there a better way to configure a floating point processor? I have a few TI specific optimizations that could go into the next release. What's...

I'm trying to make a design decision between a TI 6416 or DM642 (fixed point) and 6713 (floating point) platform. The application is a 32 channel speech encoder. (CBR only, 8khz, 8kbps) To get a feel for the computational load, I am running 1 second (50 frames) of voice through the encoder. My profile of the 6416 indicates I'm at 27.4M cycles/channel. I need to get below 720Mhz/32

Hi Jim, > Build 11169 in SVN works correctly. Good. I'll try not to forget the EXTEND32 from now on. > I have attached a zip file (renamed > .txt) with a patch to bits.c to make the byteswapping for TI DSPs > consistent. Seems like unzip can't read it. Either it's in an unknown format or the file got corrupted. Could simply send as multiple (uncompressed)
