[Speex-dev] How to get audio data from microphone on pocketPC ?

[Jere Malinen]

Hi

You should try using fmod(www.fmod.org) for recording. You need fmodce for
pocketpc, and there is recording sample included. Also you should download
fmodex, because there is record to disk sample. I have developed
application for pocket pc which records sound in a wav file.

My problem is that I have not been able to encode sound to speex in pocket
pc. So I have also question for you: do have working speex.dll and
speex.lib for pocket pc? How did you do that? Could you send those files
to me?
