2006-02-22Fix some of the voice and beep bugs that people have noticed since my new ↵Brandon Low
pcmbuf code went in, reduce code duplication, and improve performance while I'm at it git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8775 a1c6a512-1295-4272-9138-f99709370657
2006-02-13Add comments, and prevent a nearly impossible wrapping bug. There's always ↵Brandon Low
enough space for the next whole audio chunk now, so it's faster too git-svn-id: svn://svn.rockbox.org/rockbox/trunk@8678 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
