* Misc. buffering related playback tweaksBrandon Low2007-11-03
| | | | git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15435 a1c6a512-1295-4272-9138-f99709370657
* Improve upon my hackity hack from before by separating audio into two types: ↵Brandon Low2007-11-02
| | | | | | that which may be large and can be streamed and that which is small and cannot be streamed. While modifying types, allow codecs to split across the buffer wrap and dig out/move around the code that reads a codec off of the buffer to facilitate that simple sounding change. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@15408 a1c6a512-1295-4272-9138-f99709370657

* Initial, work-in-progress, version of a WMA codec using Michael Giacomelli's ↵Dave Chapman2007-07-03
| | | | | | fixed-point and malloc-less WMA decoder (based on the ffmpeg WMA decoder from early 2006, and also building on the work started by Paul Jones). The codec itself and the ASF parsing code were written by me, inspired by the ASF parser in libasf. Current performance is around 400% realtime on gigabeat, 100% realtime on PP and 20% realtime on Coldfire. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13769 a1c6a512-1295-4272-9138-f99709370657

No API version change since it should only be an issue for 64-bit sim builds. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@13233 a1c6a512-1295-4272-9138-f99709370657

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
* SWCODEC Recording Codecs: Fix problems with hanging recording screen ↵Michael Sevakis2007-03-04
| | | | | | (chiefly on x5) when no voice file present and source is not FMRadio. Caused by extra audio stops causing encoder to unload prematurely. Fix is to have separate stop flags for each codec type to prevent collisions. Also now safe to plug into USB when recording and encoder will stay loaded and not be stopped by the call to audio_stop_playback. Additional discovery: playback will not be able to restart after a USB plug during recording. Probably an old bug. I recommend in the future that recording have higher priority on system resources than playback and playback be denied access explicitly if recording requires them. Codec API becomes incompatible so do full updates. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12579 a1c6a512-1295-4272-9138-f99709370657
* SWCODEC: Dsp speed optimizations. Changes for more modularity. Removal of ↵Michael Sevakis2007-02-24
| | | | | | some usless stuff. Some assembly routines for Coldfire with speed in mind over size for the outputs but the channel modes remain compact. Miscellaneous coldfire asm updates to accomodate the changes. Codec API structure version has to increase so do a full update. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12472 a1c6a512-1295-4272-9138-f99709370657

Will fix any important patches in the tracker so they compile. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@12259 a1c6a512-1295-4272-9138-f99709370657
* Fix resampling clicking as much as possible at the moment. 1) Upsampling ↵Michael Sevakis2007-02-07
| | | | | | 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

Also, removed double variables in codecs storing a pointer to codec_api. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@11606 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
