[PATCH 0/5] ARM NEON optimization for samplerate converter
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

[PATCH 0/3] misc. cleanup
Hello,
some misc. cleanup patches for speexdsp, nothing big
I'm not sure about how to submit patches, so this is a test balloon :)
ultimately, I'd like to fix the FIXED_POINT issue, see
http://lists.xiph.org/pipermail/speex-dev/2013-December/008465.html
currently, I think the only way to find out how speexdsp has been compiled is
to resample some bytes and observe the output; which is
