* EQ settings: Rework the settings to clean up the config file.Jonathan Gordon2013-02-09
| | | | | | | | | | | | | | | | | | | Instead of 3 cfg lines per eq band there is now a single line for each: <config name>: <cutoff/center freq>, <q>, <gain> In addition, the config value names make a bit more sense. The old settings are still readable but config.cfg and any new settings files will be written with the new config values. (The old settings will be removed completly sometime after the next stable release). Also a slight rework of the advanced EQ menu UI Change-Id: I9008658d36ded442a5f2f825916df42a3934cbef Reviewed-on: http://gerrit.rockbox.org/394 Reviewed-by: Jonathan Gordon <rockbox@jdgordon.info>

* Fundamentally rewrite much of the audio DSP.Michael Sevakis2012-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Creates a standard buffer passing, local data passing and messaging system for processing stages. Stages can be moved to their own source files to reduce clutter and ease assimilation of new ones. dsp.c becomes dsp_core.c which supports an engine and framework for effects. Formats and change notifications are passed along with the buffer so that they arrive at the correct time at each stage in the chain regardless of the internal delays of a particular one. Removes restrictions on the number of samples that can be processed at a time and it pays attention to destination buffer size restrictions without having to limit input count, which also allows pcmbuf to remain fuller and safely set its own buffer limits as it sees fit. There is no longer a need to query input/output counts given a certain number of input samples; just give it the sizes of the source and destination buffers. Works in harmony with stages that are not deterministic in terms of sample input/output ratio (like both resamplers but most notably the timestretch). As a result it fixes quirks with timestretch hanging up with certain settings and it now operates properly throughout its full settings range.
