2007-05-10Code cleaning - remove some unnecessary defined(SIMULATOR) checksDave Chapman

2007-03-19SWCODEC: Get rid of extra swap buffer and get back 512K of RAM or 100K if ↵Michael Sevakis
the players RAM is <= 1MB. Make any needed changes to things to stabilize and facilitate this including removing flattening out initialization. Comment some things heavily. Fix a few logfs I didn't want to see the compiler complaining about. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12843 a1c6a512-1295-4272-9138-f99709370657
2007-02-07Fix resampling clicking as much as possible at the moment. 1) Upsampling ↵Michael Sevakis
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
2006-11-06Big Patch adds primarily: Samplerate and format selection to recording for ↵Michael Sevakis
SWCODEC. Supprort for samplerates changing in playback (just goes with the recording part inseparably). Samplerates to all encoders. Encoders can be configured individually on a menu specific to the encoder in the recording menu. File creation is delayed until flush time to reduce spinups when splitting. Misc: statusbar icons for numbers are individual digits to display any number. Audio buffer was rearranged to maximize memory available to recording and properly reinitialized when trashed. ColdFire PCM stuff moved to target tree to avoid a complicated mess when adding samplerate switching. Some needed API changes and to neaten up growing gap between hardware and software codecs. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11452 a1c6a512-1295-4272-9138-f99709370657

2006-02-07Rework PCM bufferBrandon Low
* Linked list instead of static array buffer pointers * Variable sized chunks * Improved mix handling * Reduction in duplicated code * Reduced IRAM usage w/o sacrificing performance * Converted to almost entirely unsigned math * Add pause function to reduce pcm_* exposure to playback. This WILL break playback on the iPod until linuxstb makes a followup commit. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8612 a1c6a512-1295-4272-9138-f99709370657
