Diego Biurrun	0339fab8fc	Remove unused variable. Originally committed as revision 8681 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
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	50df67d3b5	optimize bessel function instead of trusting gcc to do trivial optimizations (as gcc doesnt ...) Originally committed as revision 8474 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
