* swr: limit phase_shift to a less insane value.Michael Niedermayer2013-01-27

* swr: limit buffer size for discarding.Michael Niedermayer2013-01-13
| | | | | | | This prevents insane memory usage in case of insane input values. Untested due to lack of a testcase that causes such insane allocation Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* lswr: Improve default resampler's default parametersAlexander Strasser2013-01-04
| | | | | | | | | | | | | | 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>
