2007-06-08Straighten out some audio path APIs and misc. audio stuff. Having recording ↵Michael Sevakis
is not a prerequisite to having input/output source selection which is probably most useful when adding a audio input features like FM to a new port without forcing recording to be implemented first. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13599 a1c6a512-1295-4272-9138-f99709370657
2007-04-25Make recording complain about every little file I/O problem (error on ↵Michael Sevakis
close() failure and fsync() failure). Why? I guess we will find out the disk is full about 1/2 sector sooner on average when the file APIs actually detect this correctly. :/ git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13262 a1c6a512-1295-4272-9138-f99709370657

Hunt down and remove the remaining ones in the recording system as well. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12955 a1c6a512-1295-4272-9138-f99709370657
2007-03-20More logf fixes. speex.c wants to format 64bit args so I didn't change that ↵Michael Sevakis
one nor add any formatting for that. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12858 a1c6a512-1295-4272-9138-f99709370657
2007-03-05More catching up on old work. Refine audio interface setup on Coldfire. Stop ↵Michael Sevakis
the funky glitching on the iAudio stuff when starting recording esp. at 88.2kHz. (probably due to the bidi interface). iRivers don't seem to care what you do. TLV320 still seems to have a little trouble selecting it's filters correctly for 88.2kHz or it could be some odd phasing effect. Get rid of the horrible reset parameter in pcm_apply_settings as it can decide for itself. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12618 a1c6a512-1295-4272-9138-f99709370657
2007-03-04Dual core support for PP502x players (iPod G4 and later, iriver h10, Sansa - ↵Daniel Ankers
iPod G3 will be coming soon.) This allows threads to be run on either core provided that all communications between the cores is done using uncached memory. There should be no significant change in battery life from doing this. Documentation (on the RockboxKernel wiki page) will follow shortly. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12601 a1c6a512-1295-4272-9138-f99709370657

2007-02-16SWCODEC Recording: Improve buffer handling by 1) Lowering watermark for ↵Michael Sevakis
flushing 2) Flushing down to a low watermark instead of a fixed number of chunks 3) Allowing in-process automatic flushes to be interrupted so file splits and stops can be marked in a timely manner (especially important when approaching 2GB limit) 4) Flush small amounts if buffer is filled during a split to protect integrity of streams 5) Boost both pcmrec and codec threads then thread priority boost is needed so that encoder doesn't fail to run and keep up with incoming data git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12332 a1c6a512-1295-4272-9138-f99709370657

2006-12-10Place all recording functionality on pcmrec thread to serialize all ↵Michael Sevakis
recording operations. Button mash problems should be ruled out of pcm_record.c. Add additional lightweight checks by default and display any warnings that occurred during recording in first line of recording screen when they occur by blinking back and forth from warning display to normal line (Warning: <hex bitmask>). Warnings are cleared when beginning a new recording so write the number down if you see it and file a report. Add heavier checks when PCMREC_PARANOID is defined in the player config header (encoders and pcm_record must be aware of the define since it changes the chunk header format). These checks are mainly concerned with things that may cause skipping but also add unwanted overhead for normal operation. Best used with logf enabled. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11705 a1c6a512-1295-4272-9138-f99709370657
2006-12-07SWCODEC Recording: 1) Fix minor bug of not subtracting line aligment ↵Michael Sevakis
adjustment from buffer size. 2) Handle stop and pause better and let pcmrec thread lock the DMA as that could cause prerecording to get disabled internally 3) Make sure to snapshot DMA write index to ensure compiler doesn't perform multiple access when calculating available data (probably just paranoia on my part) 4) Handle USB connect in recording thread a little better by resetting hardware to defaults after closing 5) Make power managment stop recording properly when powering off (ie. no yield() from interrupt handler! :) git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11685 a1c6a512-1295-4272-9138-f99709370657
2006-12-06Small change to PCM recording API for low latency effects. Latency can be as ↵Michael Sevakis
low as 14 samples from input to output including the FIFOs (ColdFire) but 16 is more reasonable an expectation if only tranferring one sample per interrupt (\!). May convert PCM playback to use the same method as it can still be used in the old manner with some slight mods but has the potential to enable new features since it is more flexible. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11668 a1c6a512-1295-4272-9138-f99709370657

2006-11-29PCM: A few tiny changes. 1) Recording a) Flush all pending files if filename ↵Michael Sevakis
queue is full or else perpetual flushing of 1 will occur at low bitrates and short split times. b) #ifdef out currently unused bits and save little less than 1/2K 2) Cleanup some declarations. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11623 a1c6a512-1295-4272-9138-f99709370657
2006-11-23iRiver/iAudio: Added audio_set_recording gain and sound_default to plugin ↵Michael Sevakis

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

switching should be more efficient and tasks are stored in linked lists to eliminate unnecessary task switching to improve performance.

Thanks to Jens Arnold for fixing the DMA hang issue. Will reset settings! git-svn-id: svn://svn.rockbox.org/rockbox/trunk@9916 a1c6a512-1295-4272-9138-f99709370657

2006-04-30The recording buffer should not try to use the voice buffer, so map our ↵Peter D'Hoye
