2006-12-18FS#6096. Recording on PortalPlayer targets (H10, iPod Video, iPod 4g, iPod ↵Barry Wardell
Color, iPod Nano). * Fix failed compile of enc_config.c when HAVE_MPEG2_SAMPR is not defined. * Fix bug in AIFF encoder header creation on little endian targets. * Add recording screen keymaps for H10 and iPod. * Move pcm_playback PP specific code to target tree. * Add recording code to wmcodec drivers. * Add pcm_record code. Some problems still remain: * Playback doesn't work after recording until Rockbox is restarted. * Gain control not implemented. * Only 16-bit/44KHz for now. The hardware should be capable of up to 24-bit/96KHz. * Line-in recording not tested on H10. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11794 a1c6a512-1295-4272-9138-f99709370657

2006-11-23iRiver/iAudio: Added audio_set_recording gain and sound_default to plugin ↵Michael Sevakis
API. Simplified plugin recording by target/-ing some audio functions. UDA1380 records with WSPLL as a result. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11577 a1c6a512-1295-4272-9138-f99709370657
2006-11-22Audio bugfixes. Should wait for voice codec to reload before returning ↵Michael Sevakis
buffer when stealing voice. Certain variables that get or may get used during an IRQ should be declared 'volatile'. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11572 a1c6a512-1295-4272-9138-f99709370657

2006-11-06Big Patch adds primarily: Samplerate and format selection to recording for ↵Michael Sevakis
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
