...t;jsarha at ti.com> Semantics of inner_product_single have also been changed to contain the final right shift and saturation so it can also be implemented in the optimal way for the used platform. This change affects fixed point calculations only. I also added a new fixed point macro SATURATE32PSHR(x, shift, a). It does pretty much the same thing as SATURATE32(PSHR32(x, shift), a), but it avoids over flowing in rounding up phase in the rare occasion where x has already been saturated. It should also be slightly faster. --- libspeex/arch.h | 1 + libspeex/fixed_generic.h | 4 ++...

From: Jyri Sarha <jsarha at ti.com> I optimized Speex resampler for NEON capable ARM CPUs. The first patch should speed up resampling on any platform that can spare the increased memory usage. It would be nice to have these merged to the master branch. Please let me know if there is anything I can do to help the the merge. The patches have been rebased on top of master branch in

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

...Jim, Thanks a lot for investigating. It definitely makes sense now. I'll fix the problem now. Is there any other place where you see that same (or similar) problem?
