| | | | | | | | | | | | | | | | | | | | 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

* Big Patch adds primarily: Samplerate and format selection to recording for ↵Michael Sevakis2006-11-06
| | | | | | 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
