528fe442fc New recording setting to configure how mono recordings are made. Previously, this was always L+R, which was kinda silly if your signal was on L only. This setting allows for L, R or L+R. SWCODEC only for now, to be added for HWCODEC (although that will only be L and L+R probably)

6b84f60046 APE: Further ARMv6 filter optimisations: Save 4 'ror's per round by utilising the shift feature of the 'pack halfword' instructions in the unaligned vector addition/ subtraction, better pipelining in the aligned scalarproduct(), and a new method to calculate the unaligned scalarproduct().

d1b19be423 Various speedups: (1) Put actual decoding functions into IRAM on PP5002. (2) Put the insane filter buffer into IRAM on coldfire and PP502x (just for completeness, as long as there's no better use). (3) Use the ARMv6 'ssat' instruction for saturation on Gigabeat S.

726a63f309 Correct version of memory sizes in config-logikdax.h (previous values were just experimental and should not have been committed). We also need to remove two more codecs for this codec buffer size (128KB). The m200 and DAX builds now actually build.

85807cd44e Trivial changes to make the main Rockbox builds for the Sansa m200 and Logik DAX ports compile. Note that some codecs are currently disabled (due to lowmem on these targets), but that needs more work and analysis to decide how much RAM we want to allocate to codecs.

4e36a2b991 Commit FS#9318 - MP3 synthesis filter on COP. Loads the MP3 synth filer on to the CoProcessor on all PortalPlayer devices, resulting in an ~90% speedup according to test_codec on the Sansa. Real world improvement is somewhat less, but still considerable. Allows MP3 decoding at 30MHz without boosting, or use of more DSP/EQ with less boosting/skipping, thus improving battery life. Minor changes to mpegplayer to retain compatibility with libmad changes. Should be no significant changes for other targets or codecs.

46f85c4c54 Combine the Vorbis, WMA and AAC IMDCT functions and put them into the codeclib. Combined IMDCT is now based on existing Tremor transform. Reduces CPU for 192k AAC by 21MHz on Coldfire, and 5MHz on PP5024. WMA and Vorbis should have no functional changes since they already used this code. Further optimization is possible and would benefit all 3 codecs.

1334738071 Use Tremor IMDCT for WMA. Gives a ~20% speedup on ARM and coldfire. All my test samples gave equivilent or better accuracy (>>16 bit), but there may still be problems. Code becomes somewhat less readable since the IMDCT has bits of Vorbis in it, but this is not a serious issue and the old ffmpeg transform remains in SVN if anyone wants it. Also, WMA now passes Vorbis as the fastest transform codec on ARM, although MPC remains the fastest lossy codec overall.
