Hi, I'm using the Speex codec on my Blackfin-based board, and plain-C performance is pretty poor. Decoder is OK (something 25 MIPS for wide-band). But Encoder is not (wide-band quality 8, complexity 1): - 162 MIPS with Analog-Devices lib - 128 MIPS with 1.2beta2 (faster but not working) I don't worry that much, as it's not the optimized version, and everything is running in SDRAM.

...n we'd need to investigate > that first. I compiled 1.2beta1, beta2, and the SVN from yesterday. Beta1 works fine, but starting from beta2, the sound is scrambled... Of course, project options are identical. Did you change something in the API ? Do I need to initialize extra things ? See myspeex.c code. It's pretty simple. I noticed a very interesting thing: the echo-cancellation totally removes this problem !!! How can I help you debug this thing ? My platform is Blackfin fixed-point on visual DSP. I can't use the debug-out on VDSP (too slow), but my custom-board has IP and RS23...
