Speex dev - Dec 2005 - Speex - Real time??

Hi. I tried encoding a raw PCM file to Speex in my Windows Mobile device and
it took about 45 seconds to encode a 10-second file. I had FIXED_POINT
defined and used speex_encode_int. The device has an ARMV4 400 MHz
processor. Question: Is this behavior expected or is it possible to encode
speech to speex real-time such that I can record speech directly as speex in
my device? What, if any, can be done to speed up encoding time? As expected,
decoding was no problem. I was using version 1.1.10.

Thank you for all the help,
Monica

You should definitely be able to do narrowband in realtime. For
wideband, it depends on the mode and complexity setting. Try setting the
complexity to one:

int tmp = 1;
speex_encoder_ctl(encoder, SPEEX_SET_COMPLEXITY, &tmp);
