[speex-dev] [ANNOUNCE] PocketPC Port for speex-1.1.5 with sample code

Tue Jun 1 11:50:15 PDT 2004

I emailed Jean-Marc the arch.h about one week ago, not quite sure whether he
actually received that email.

Anyway, here I have an improved version of arch.h that I believe that it
would be better, to use __int64 only if compiling on eMbedded Visual C++
compiler, so for any other compiler, keep it the same (use long long)

code

Hi Jean-Marc, 

Based on the wonderful Speex project, I've created SpeexOutLoud, essentially
a Speex codec port for Windows Mobile 2003 devices. 

I've included a sample project intended to show the usage of SpeexOutLoud
codec in a Pocket PC application based on .NET Compact Framework.

I'd request you to please go through the attached build, and include it as a
contribution to the ever-increasing group of people making use of Speex.

If you feel the code is OK; it should probably go somewhere beneath the
win32 directory within speex-1.1.x, and with the speex sample code.

Please let me know if you have any queries/comments/suggestions. The
attached README has compile/usage/bug-notes. 

Thanks & regards, 
Asheesh
