This is an updated set of patches first announced and discussed here: http://comments.gmane.org/gmane.comp.audio.pulseaudio.general/22158 Changes to the original patches: * Removed the -lq quality preset, only -mq, -hq and -vhq presets are left. * Removed the fix to the sample_format_more_precise function as it was factored out to a separate patch, which was committed. * Changed the asserts in switch/case statements to the pa_assert_not_reached() macro and also some comments as suggested. * Explicitly provide runtime_spec with thread number 1 to soxr_create so that we're guaranteed to not use multithreading. This is equivalent to the previous code that relied on the default. * Changed choose_work_format() so that soxr uses the common case branch rather than its own. Removed the duplicate condition from it to simplify code slightly. * Updated docs so that it better describes pros and cons of the new resampler and its presets.
