<div>Hi there, </div>
<div> i'm not into speex internals but i feel that your problems are due to the fact</div>
<div>that speex doesn't do yet fixed point operations and it seems that you lack</div>
<div>FPU on your PDA. So i would expect a big boost in performances when the fixed</div>
<div>point version of Speex will be out.</div>
<div> </div>
<div>Cheers,</div>

<div>Hi,<br><br>Sorry to be posting about a subject that may have already been answered. If so, please point me in the right direction.<br><br>I'm developing a dictation application on the Dell Axim (Windows Mobile 5.0 Pocket PC). A key requirement of the application is the best possible sampling rate as the audio goes into a speech reco system. So, I've set up my wrapper around libspeex to capture audio (1 channel, 22050Hz, 16 bits/sample) in blocks of the frame size. However, the encoder lags significantly - typically upwards of 2000 frames, at complexity <= 1 and quality <= 3. I've a
