2006-11-16Removed muting from pcm buffer during starts, stops and pauses for tlv320 ↵Michael Sevakis1-1/+20
and uda1380. Far less in the way of pops now. Voice during FM radio playback keeps radio steady. If it is determined that other audio codecs don't benefit from this remove the muting code and defines altogether. Saving the state and not resetting more than needed seems to prevent popping more effectively than muting at DMA starts and stops. Voice can click a little if truncating a clip (not annoyingly though) but that should be handled by a DSP fade out over a few ms instead-- a side benefit would be a general DSP fade rather than using volume control. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11538 a1c6a512-1295-4272-9138-f99709370657

2006-11-06Big Patch adds primarily: Samplerate and format selection to recording for ↵Michael Sevakis1-8/+19
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
