2007-03-07Factor first order shelving filter code out for easier reuse and replace the ↵Thom Johansen1-53/+47
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 Johansen1-0/+2
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 Johansen1-4/+56
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 Johansen1-114/+69
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

2006-10-18Two more bits of precision for shelving EQ filters and some comment updates. ↵Thom Johansen1-55/+74
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

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
