2008-06-28Updated our source code header to explicitly mention that we are GPL v2 orDaniel Stenberg
later. We still need to hunt down snippets used that are not. 1324 modified files... http://www.rockbox.org/mail/archive/rockbox-dev-archive-2008-06/0060.shtml git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17847 a1c6a512-1295-4272-9138-f99709370657
2007-05-10Code cleaning - remove some unnecessary defined(SIMULATOR) checksDave Chapman

2007-03-07Factor first order shelving filter code out for easier reuse and replace the ↵Thom Johansen
crossfeed filter with it. Crossfeed _should_ still sound the same, so please do tell if it doesn't. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12674 a1c6a512-1295-4272-9138-f99709370657
2007-02-26Wrap filter_bishelf_coefs with HAVE_SW_TONE_CONTROLS to not waste bytes on ↵Thom Johansen
targets that don't use it. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12490 a1c6a512-1295-4272-9138-f99709370657
2007-02-26Add software based bass/treble controls for targets which have no such ↵Thom Johansen
functionality in hardware (currently only X5). They can also be used on any other SWCODEC target by adding #define HAVE_SW_TONE_CONTROLS in the relevant config-*.h file. Also remove some now unneeded zero checks when using get_replaygain_int(). Comments on sound quality are welcome as some parameters can still be fine-tuned. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12489 a1c6a512-1295-4272-9138-f99709370657
2007-02-05Optimise EQ coef calculation routines for both speed and size. Move now ↵Thom Johansen
unneeded fsqrt function to plugin fixed point library in case it'll be needed. Move all fixed point helper macros to dsp.h. Added FRACMUL_SHL macro to facilitate high-precision shifting of 64 bit multiplies and remove rounding from macsr in main thread to make this work as intended. Tested quite thorougly, but as always, be careful with your ears. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12203 a1c6a512-1295-4272-9138-f99709370657
2006-12-12More static'ing, and a few fixes resulting from that.Jens Arnold

2006-10-18Two more bits of precision for shelving EQ filters and some comment updates. ↵Thom Johansen
Tested quite thoroughly, but as always with audio related commits: mind your ears. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11265 a1c6a512-1295-4272-9138-f99709370657
2006-04-11New crossfeed complete with no volume reducing bugs. Feedback on all theThom Johansen
new options is appreciated. Thanks to Dan Everton for the settings/GUI code. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@9609 a1c6a512-1295-4272-9138-f99709370657
2006-03-23Make EQ work on 64 bit sims again.Thom Johansen

2006-03-23Fix the inaccurate frequency setting problems of the EQ due toThom Johansen
inaccuracies in the sin/cos functioncs. A million thanks to safetydan for fixing my crappy trig functions! git-svn-id: svn://svn.rockbox.org/rockbox/trunk@9209 a1c6a512-1295-4272-9138-f99709370657
2006-03-21Further 64 bit related fixes. EQ should now work in AMD64 sim.Thom Johansen
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@9142 a1c6a512-1295-4272-9138-f99709370657
2006-03-19Samples should always be 32 bit on all platforms, so change mostThom Johansen
occurences of long to int32_t to enable working sounds also on 64 bit sims. Note that some codecs (MP3 and Wavpack) still have other 64 bit related problems. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@9120 a1c6a512-1295-4272-9138-f99709370657
2006-03-09C implementation of eq filter. Allows equalizer to be used in the simulator. ↵Dan Everton
Code from preglow. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8973 a1c6a512-1295-4272-9138-f99709370657

2006-01-29Slight change of coef format. Removed erronous hard code of channelThom Johansen
number in EQ filtering routine and added some minor changes. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8486 a1c6a512-1295-4272-9138-f99709370657
2006-01-29Initial multi-band EQ support for software codec platforms. Now go startThom Johansen
