memory targets (mainly AMS) to save memory. Some crossfade related items remain in the code, but they're not worth cluttering the code with ifdefs over. Also, introduce HAVE_CROSSFADE define for neatness. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@22248 a1c6a512-1295-4272-9138-f99709370657

say at this point about any change in battery life but it frees up a percent or two of CPU cycles as measured in the buffering screen. No change in recording transfers yet.

2009-02-16Fix too-soon frequency unboost when pcm buffer crosses watermark from the ↵Michael Sevakis
low side. It's supposed to stay boosted until full again. Also align the static beep buffer to 4 bytes. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@20017 a1c6a512-1295-4272-9138-f99709370657

2008-12-13Keyclick fixup take two. It is only 88 samples (2msec) long so keep a small ↵Michael Sevakis
static buffer around for beeps less than or equal to keyclick duration.

2008-12-10Use cookies for thread identification instead of pointers directly which ↵Michael Sevakis
gives a buffer against wrongly identifying a thread when the slot is recycled (which has been nagging me for awhile). A slot gets 255 uses before it repeats. Everything gets incompatible so a full update is required. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19377 a1c6a512-1295-4272-9138-f99709370657
2008-12-07Meg F/X can beep and click using a hardware timer so let us try it out. To ↵Michael Sevakis
match things up better, fix PCM beeping to give correct frequency (and get a pointer wrap bug too). Do some minor adjustments to compensate for corrections. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@19355 a1c6a512-1295-4272-9138-f99709370657
