* Small change to PCM recording API for low latency effects. Latency can be as ↵Michael Sevakis2006-12-06
| | | | | | low as 14 samples from input to output including the FIFOs (ColdFire) but 16 is more reasonable an expectation if only tranferring one sample per interrupt (\!). May convert PCM playback to use the same method as it can still be used in the old manner with some slight mods but has the potential to enable new features since it is more flexible. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11668 a1c6a512-1295-4272-9138-f99709370657

* Big Patch adds primarily: Samplerate and format selection to recording for ↵Michael Sevakis2006-11-06
| | | | | | 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
* Rework PCM bufferBrandon Low2006-02-07
| | | | | | | | | | | | | | | * 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
