Opus on Analgo Devices ADSP-21489
Hi, I am evaluating the opus codec for use in an embedded design. I have successfully ported opus on a TI C5502 (fixed poin dspt) but need to use a more powerful dsp processor for our application. With the C5502 it takes 4.5ms to encode 2 (mono) channels with a 5ms frame @80kbits per channel. I need to reduce the computing time to reduce latency and leave some time for the DSP to perform some

speex echo problem in my own softphone to POTS
Hi, I use SpeexEcho in my own softphone using MGCP protocol register to a PBX under WindowsXP in my laptop. I make a call: softphone ---> PBX ----> MediaGateWay ---PotsLine---> Traditional Phone. In the other side(TraditionalPhone), I did not here any echo voice, SpeexEcho works well. But, if I let laptop to make some sounds, such as play music, I heard all

Blackfin inline assembler and VisualDSP++ toolchain
> >Actually, you're the first I know using the VisualDSP++ toolchain :-) > I guess that's because speex has pretty big memory footprint. So developers that integrate speex tend to have plenty of RAM and once one has plenty of RAM he could install biggish OS. And between biggish OSes for Blackfin the most popular choice is uCLinux. And ucLinux works best with gnu tools. Something

how to fix high freq noise?
