[Speex-dev] echo cancellation on PDA

Hello all,

Today I tried speex echo cancellation on my VoIP application running
on a windows mobile based PDA (OMAP1510 168MHz). The result is
disappointing: it takes 150-250 ms to do echo cancellation (by calling
speex_echo_capture() ) for a 20 ms frame!

I've defined the FIXED_POINT macro. Is there anyway to do some optimization?
