Adam Gashlin	88c0d9d80f	VRC6 speedup/bugfix from Takashi Obara, FS #6635 ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12239 a1c6a512-1295-4272-9138-f99709370657	2007-02-09 08:41:43 +00:00
Michael Sevakis	aba6ca0881	Fix resampling clicking as much as possible at the moment. 1) Upsampling clicked because of size inaccuracies returned by DSP. Fix by simplifying audio system to use per-channel sample count from codec to pcm buffer. 2) Downsampling affected by 1) and was often starting passed the end of the data when not enough was available to generate an output sample. Fix by clamping input range to last sample in buffer and using the last sample value in the buffer. A perfect fix will require a double buffering scheme on the resampler to sufficient data during small data transients on both ends at all times of the down ratio on input and the up ratio on output. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12218 a1c6a512-1295-4272-9138-f99709370657	2007-02-07 00:51:50 +00:00
