2013-04-11Implement universal in-PCM-driver software volume control.Michael Sevakis
Implements double-buffered volume, balance and prescaling control in the main PCM driver when HAVE_SW_VOLUME_CONTROL is defined ensuring that all PCM is volume controlled and level changes are low in latency. Supports -73 to +6 dB using a 15-bit factor so that no large-integer math is needed. Low-level hardware drivers do not have to implement it themselves but parameters can be changed (currently defined in pcm-internal.h) to work best with a particular SoC or to provide different volume ranges. Volume and prescale calls should be made in the codec driver. It should appear as a normal hardware interface. PCM volume calls expect .1 dB units.

2013-03-06VGM Codec: Improve time and fade behavior. Tweak minor misc.Michael Sevakis
Prevents cutoff of tracks, especially short ones: * Extend looped tracks by fade length to fade at start of loop repeat. * No fade occurs for non-repeating track only having an intro. * Uses id3.tail_trim field to store fade duration. Use libGME built-in elapsed time reporting instead of custom calculation: * libGME already reports in milliseconds. * Don't advance time counter when Repeat == One. It just runs the progress over the length limit. Fix a comment about sample rate and set the reported bitrate to be accurate for 44.1 kHz stereo. Change-Id: I3ede22bda0f9a941a3fef751f4d678eb0027344c

2013-02-09EQ settings: Rework the settings to clean up the config file.Jonathan Gordon
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>

2012-11-22Add support for 16 bit 'half float' format PCM.Michael Giacomelli
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

2012-05-28New crossfeed algorithm for Rockbox: "Meier" crossfeedBertrik Sikken
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
