2013-03-01soxr: libsoxr 0.1.1 supportRob Sykes
Libsoxr 0.1.1 will be out very soon; no changes planned beyond what's currently in git. It includes a couple of fixes (not affecting FFmpeg's current usage) and a minor API change (but remains ABI compatible). Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

2013-01-04lswr: Improve default resampler's default parametersAlexander Strasser
After making some blind tests on a small collection of music samples for home usage. It turned out that the default cutoff was too low. The impact of filter_size was not clearly distinguishable (the results were on the edge) with the music samples but turned out to be clearly audible in some synthetic samples. Thanks to Daniel for helping out with the listening tests. Signed-off-by: Alexander Strasser <eclipse7@gmx.net>
