[speex-dev] Libspeex-cygwin-EVC++ 3.0

[Rodrigo Parra M]

Hello Carl,
Can you send me libspeex compilated in eVC. And can you describe where and how set the FIXED_POINT flag in eVC.
Thanks you.
Regards.
Rodrigo.

    I have built the Speex library for Pocket PC using the FIXED_POINT flag in eVC 3.  It works fine.
    I think the iPAQ 3600 (ARM SA 1110, I think this is a 200mhz cpu), is a bit slow for encoding in realtime. The Speex encode function takes 30+ ms to encode one 20ms sample frame in a debug build. I didn't try the release build with compiler optimization.
    
    The iPAQ 3970 (PXA250, I think this is a 400mhz cpu?)  is just fast enough for realtime encoding - the Speex encode function takes 20+ ms to encode one 20ms sample frame without compiler optimizations, but with compiler optimizations and tracing removed, only on occaisional tests did I notice gaps in the stream.
    
    My experiments were done with 1 channel, 16 bit, 8000hz samples, using Speex quality 3 and complexity 4.
