[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
