2009-06-16Get rid of tdspeed_enabled in struct dsp_config and use the global_settings ↵Thomas Martitz
member instead. That one needs to be checked in tdspeed_init() as well, else the buffers are always allocated. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21305 a1c6a512-1295-4272-9138-f99709370657

2008-09-08Add timestretching from FS#8894, as written by Stephane Doyon based on work ↵Steve Bavin
by Nicolas Pitre. Shouldn't affect playback unless it's explicitly enabled, but let me know if it does. Currently has a dedicated setting, but maybe inclusion of the code will inspire someone to integrate this with the pitch screen... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@18446 a1c6a512-1295-4272-9138-f99709370657

2008-04-08Remove ACC_INIT, ACC and GET_ACC macros. These were quite Coldfire-centric ↵Thom Johansen
macros which really aren't needed since all performance sensitive target DSP code should be assembler anyway. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@17037 a1c6a512-1295-4272-9138-f99709370657
2008-03-20Turnaround time must be included in dsp yielding to throttle against other ↵Michael Sevakis
threads. Do at least one per buffer full as well (or things can stick a bit on initial input triggers). git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16721 a1c6a512-1295-4272-9138-f99709370657
2008-03-19Commit FS#8750. Add ARM assembler for the dsp-functions ↵Andree Buschmann
channels_process_sound_chan_mono(), channels_process_sound_chan_karaoke(), sample_output_mono() and sample_output_stereo(). By measurement the speed up is ~75% for the first three functions and ~40% for sample_output_stereo(). Additionally avoid calling yield() to often in dsp.c -- it is now limited to once per tick. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@16717 a1c6a512-1295-4272-9138-f99709370657
2007-12-08Crossfeed settings used to be stored inverted in the cfg file for legacy ↵Thom Johansen
reasons, change that and kill some identical formatting functions while we're at it. NOTE TO CROSSFEED USERS: this will completely garble your crossfeed settings, write them down if you want to keep them. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15895 a1c6a512-1295-4272-9138-f99709370657

bug would only affect people using WMA. Also, add a small comment in an unrelated place. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15369 a1c6a512-1295-4272-9138-f99709370657

2007-03-25SWCODEC & Coldfire: Do some more DSP straigntening out. Do as much Coldfire ↵Michael Sevakis
optimizing as seems reasonably possible by jumping through some hoops to avoid stalls. Further boost reduction will just be fractional points if taken to extremes-- not worth it. Wrap up the ASM for awhile. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12905 a1c6a512-1295-4272-9138-f99709370657
2007-03-07Use the new DSP callback functionality in firmware/sound.c to deal with ↵Thom Johansen
SWCODEC stereo width and channel configuration instead of the old more spread out #ifdef based approach. Rename the DSP functions involved for more consistent naming. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12677 a1c6a512-1295-4272-9138-f99709370657
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
2007-02-28SWCODEC: Patchup the short crossfade glitching reported for FLAC but seemed ↵Michael Sevakis
not limited to FLAC actually. Crossfade doesn't like being hand the larger chunks that the dsp was now able to process when not resampling. The real fix is making it not matter. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12521 a1c6a512-1295-4272-9138-f99709370657
