Michael Sevakis	4db3e89652	Shuffle some functions around so that interfacing with playback.c in particular isn't required. Though playback does finish the audio init, pcm doesn't care who does it. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30403 a1c6a512-1295-4272-9138-f99709370657	2011-09-01 12:15:43 +00:00
Michael Sevakis	22b6def065	Use playback channel directly for peakmeters and plugins using peak calculation. Also, for now, don't allow mixer playback to overlap recording, even if full duplex works. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30119 a1c6a512-1295-4272-9138-f99709370657	2011-07-02 11:55:38 +00:00
Michael Sevakis	a2b6703a36	Commit FS#12150 - Fully-functional audio mixer - and finally whip old limitations about playback of voice and other sounds when paused. Channels are independent in state and amplitude. Fade on stop/pause is handled by the channel's volume control rather than global volume which means it now works from anywhere. Opens up the possibility of plugin sounds during music playback by merely adding an additional channel enum. If any PCM drivers were not properly modified, see one of the last comments in the task for a description of the simple change that is expected. Some params are tunable in firmware/export/pcm-mixer.h as well. ... git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30097 a1c6a512-1295-4272-9138-f99709370657	2011-06-29 06:37:04 +00:00
