2007-11-18Make speex the new voice format for SWCODEC targets (non-Archos). Remove ↵Michael Sevakis
codec swapping and build speex voice decoding directly into the core binary. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15668 a1c6a512-1295-4272-9138-f99709370657

git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15638 a1c6a512-1295-4272-9138-f99709370657
2007-11-16Use sized data types for audio data in the pcm buffer. Speed up the clipping ↵Michael Sevakis
routine. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15636 a1c6a512-1295-4272-9138-f99709370657
2007-10-06Unify PCM interface just above the hardware driver level for all targets ↵Michael Sevakis
including the sims. Perform lockout of audio callback when changing states. Weird new playback or recording trouble? Check before and after this revision first though things seem quite sound. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15006 a1c6a512-1295-4272-9138-f99709370657
2007-06-24SWCODEC: Get rid of unneeded pcm_mute() calls. Leave the only ones that seem ↵Michael Sevakis
to be needed for WM codecs. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13704 a1c6a512-1295-4272-9138-f99709370657
2007-03-19SWCODEC: Get rid of extra swap buffer and get back 512K of RAM or 100K if ↵Michael Sevakis
the players RAM is <= 1MB. Make any needed changes to things to stabilize and facilitate this including removing flattening out initialization. Comment some things heavily. Fix a few logfs I didn't want to see the compiler complaining about. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12843 a1c6a512-1295-4272-9138-f99709370657
2007-03-06Put the sims in their place.Michael Sevakis
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12650 a1c6a512-1295-4272-9138-f99709370657
2007-03-06Fix problem with recording screen creep and bag a bigfoot. Voice clips ↵Michael Sevakis
aren't long enough now to untrigger the thread boost that was supposed to be applied to the codec thread. The voice thread was needlessly boosting the codec thread and leaving it boosted which explains the encoders' ability to flood the output buffer when everything else was stopped in its tracks. Check which thread is calling pcmbuf_under_watermark and only initiate the boost when it's the codec thread. Always return the codec thread to its usual priority in pcmbuf_play_stop. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12649 a1c6a512-1295-4272-9138-f99709370657
2007-02-07Fix resampling clicking as much as possible at the moment. 1) Upsampling ↵Michael Sevakis
clicked because of size inaccuracies returned by DSP. Fix by simplifying audio system to use per-channel sample count from codec to pcm buffer. 2) Downsampling affected by 1) and was often starting passed the end of the data when not enough was available to generate an output sample. Fix by clamping input range to last sample in buffer and using the last sample value in the buffer. A perfect fix will require a double buffering scheme on the resampler to sufficient data during small data transients on both ends at all times of the down ratio on input and the up ratio on output. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12218 a1c6a512-1295-4272-9138-f99709370657

2006-11-22Priority overriding was not working correctly.Miika Pekkarinen
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11573 a1c6a512-1295-4272-9138-f99709370657
2006-11-16Removed muting from pcm buffer during starts, stops and pauses for tlv320 ↵Michael Sevakis
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
2006-11-07Calculation was wrong in pcmbuf_is_same_size such that is would almost ↵Michael Sevakis
certainly return false. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11460 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

2006-09-16New scheduler, with priorities for swcodec platforms. Frequent taskMiika Pekkarinen
switching should be more efficient and tasks are stored in linked lists to eliminate unnecessary task switching to improve performance. Audio should no longer skip on swcodec targets caused by too CPU hungry UI thread or background threads. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@10958 a1c6a512-1295-4272-9138-f99709370657
