[Speex-dev] Fixed point bug in 1.1.6

[Jean-Marc Valin]

Hi,

This definitely needs to be investigated. Unfortunately, I have very little time
at the moment, so it would help a lot if you (or someone else here) were able
to trace the problem a bit further.

Thanks,

> krwawa_org.wav is original file.

> Only difference was used speex library.
> krwawa_fixed.wav was created by libspeex compiled with defined FIXED_POINT
> krwawa_float.wav was created without FIXED_POINT.
>
> When samples values do not exceed (-32000;32000) eveything is ok.
> Testing platform was Pocket PC, with ARM cpu, libspeex compiled in MsEVC++4.
