* Remove unused conf_preseek from buffering.c and all of its accountraments. ↵Brandon Low2007-11-05
| | | | | | This is _not_ a setting. This is a guessing tool used by either playback or buffering to serve its clients better. Use the REBUFFER_GUESS size in resume to help obviate pondlife's bug. This will also need to be used when FS8092 gets fixed correctly with a complete rebuffer for backward movements. It may also belong in buffering not playback, haven't decided for sure git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15475 a1c6a512-1295-4272-9138-f99709370657

* Add software based bass/treble controls for targets which have no such ↵Thom Johansen2007-02-26
| | | | | | 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
* SWCODEC: Dsp speed optimizations. Changes for more modularity. Removal of ↵Michael Sevakis2007-02-24
| | | | | | some usless stuff. Some assembly routines for Coldfire with speed in mind over size for the outputs but the channel modes remain compact. Miscellaneous coldfire asm updates to accomodate the changes. Codec API structure version has to increase so do a full update. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12472 a1c6a512-1295-4272-9138-f99709370657

* Optimise/touchup some asm macros in dsp.h, and also remove some now unneeded ↵Thom Johansen2007-02-15
| | | | | | ones. Add config.h to dsp.c so that these macros actually get used, and also do some minor nitpicks to the resampler while I'm at it. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12322 a1c6a512-1295-4272-9138-f99709370657
* SWCODEC: Annoying neatness update. Use intptr_t for codec_configure_callback ↵Michael Sevakis2007-02-10
| | | | | | and dsp_configure and stop all the silly type casting of intergral types to pointers to set dsp configuration and watermarks. Shouldn't have any effect on already compiled codecs at all. Will fix any important patches in the tracker so they compile. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12259 a1c6a512-1295-4272-9138-f99709370657
* Fix resampling clicking as much as possible at the moment. 1) Upsampling ↵Michael Sevakis2007-02-07
| | | | | | clicked because of size inaccuracies returned by DSP. Fix by simplifying audio system to use per-channel sample count from codec to pcm buffer. 2) Downsampling affected by 1) and was often starting passed the end of the data when not enough was available to generate an output sample. Fix by clamping input range to last sample in buffer and using the last sample value in the buffer. A perfect fix will require a double buffering scheme on the resampler to sufficient data during small data transients on both ends at all times of the down ratio on input and the up ratio on output. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12218 a1c6a512-1295-4272-9138-f99709370657
* Optimise EQ coef calculation routines for both speed and size. Move now ↵Thom Johansen2007-02-05
| | | | | | | | | 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
