Michael Niedermayer	b5875b9111	Add libswresample. Similar to libswscale this does resampling and format convertion, just for audio instead of video. changing sampling rate, sample formats, channel layouts and sample packing all in one with a very simple public interface.

Michael Niedermayer	7e068841cb	replace long double in the audiophile kiddy mode with doubles, its faster (and more portable) and the audiophile placebo 120db stopband attenuation isnt affected Originally committed as revision 8482 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	d6fead9089	change high precision mode to 30 bits again after making the code less overflow sensitive Originally committed as revision 8481 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	303bd95cd2	optimize linear filter coeff interpolation code, this also makes the code less prone to overflows Originally committed as revision 8480 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	447caf7941	revert r8469 (increase bits for non default highprecision mode) it causes overflows with linear interpolated filters coefficients Originally committed as revision 8476 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago

Michael Niedermayer	14f887efc6	select more sensible default windows (= attenuation beyond the dynamic range of your input is silly if it negatively affects other parameters) Originally committed as revision 8473 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
