* 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>

* ARMv5 optimized complex multiply function for libopus.Michael Giacomelli2013-01-21
| | | | | | | | | | | | | Speeds up decoding of 128k opus files by 1.2MHz on AMSv2. Rounding error is 1 bit due to KissFFT using a 15 bit shift instead of a 16 bit shift. Also, change an LDMIA in the armv4 code to LDM as the pointer should not increment.

* Add support for 16 bit 'half float' format PCM.Michael Giacomelli2012-11-22
| | | | | | | | | I'm not 100% sure that the rounding of denormals is correct. As compared to foobar2000, some samples are off by +1 LSB. However, since I can't output 24 bit PCM easily with rockbox, I'm not sure if this is due to a bug or just how rockbox rounds. In practice I don't think it matters so I'm just going to commit this for now. Change-Id: Ic0792fcb172e4369a5512d202121c2b918b36079

* New crossfeed algorithm for Rockbox: "Meier" crossfeedBertrik Sikken2012-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Emulates the basic "Meier" crossfeed (2 capacitors, 3 resistors) as discussed in http://www.meier-audio.homepage.t-online.de/passivefilter.htm This crossfeed blends a bit of low-pass filtered L signal into the R signal (and vice versa) while adding about 300 us delay to the crossfed-signal. A difference with the crossfeed already present in rockbox, is that this algorithm keeps the total spectrum flat (the one currently in rockbox accentuates low-frequency signals, making it sound a bit muffled). This implementation is quite lightweight, just 3 multiplies per left-right pair of samples. Has a default C implementation and optimized assembly versions for ARM and Coldfire. The crossfeed effect is quite subtle and is noticeable mostly one albums that have very strong left-right separation (e.g. one instrument only on the left, another only on the right). In the user interface, the new crossfeed option appears as "Meier" and is not configureable. The existing crossfeed is renamed to "Custom" as it allows itself to be customised. There is no entry for the user manual yet. Change-Id: Iaa100616fe0fcd7e16f08cdb9a7f41501973eee1
