  1. 5e4532c Fix a problem with audio not starting on a list of short files by Michael Sevakis · 8 years ago
  2. 6c83739 Playback: Fix problems with crossfade on short tracks. by Michael Sevakis · 8 years ago
  3. d37bf24 Enable setting of global output samplerate on certain targets. by Michael Sevakis · 11 years ago
  4. fdd3634 Fix up some more type stuff in pcmbuf.c. by Michael Sevakis · 12 years ago
  5. 5833cc1 pcmbuf minor cleaning by Michael Sevakis · 13 years ago
  6. 7ad2cad Commit work started in FS#12153 to put timing/position information in PCM by Michael Sevakis · 13 years ago
  7. 5078d46 Fix FS#12238 - WPS delay on pause introduced by r30097 which was the excuse I wanted anyway to do a better PCM fade on stop/pause implementation. New fade is asynchronous tick-based. Restores skin update points in the WPS that were removed when fading mechanism was changed. by Michael Sevakis · 13 years ago
  8. a2b6703 Commit FS#12150 - Fully-functional audio mixer - and finally whip old limitations about playback of voice and other sounds when paused. Channels are independent in state and amplitude. Fade on stop/pause is handled by the channel's volume control rather than global volume which means it now works from anywhere. Opens up the possibility of plugin sounds during music playback by merely adding an additional channel enum. If any PCM drivers were not properly modified, see one of the last comments in the task for a description of the simple change that is expected. Some params are tunable in firmware/export/pcm-mixer.h as well. by Michael Sevakis · 13 years ago
  9. c537d59 Commit FS#12069 - Playback rework - first stages. Gives as thorough as possible a treatment of codec management, track change and metadata logic as possible while maintaining fairly narrow focus and not rewriting everything all at once. Please see the rockbox-dev mail archive on 2011-04-25 (Playback engine rework) for a more thorough manifest of what was addressed. Plugins and codecs become incompatible. by Michael Sevakis · 13 years ago
  10. 6510973 Give playback engine better control over the codec. Codec simply follows commands and doesn't concern itself with audio state. Get track change notification in on the actual last buffer insert of the track because now audio simply waits for a track change notify from PCM on the last track and it must be sent reliably. This is still at an intermediate stage but works. Codecs and plugins become incompatible. by Michael Sevakis · 14 years ago

  26. 99617d7 Make speex the new voice format for SWCODEC targets (non-Archos). Remove codec swapping and build speex voice decoding directly into the core binary. by Michael Sevakis · 17 years ago
  27. f02cba8 Code cleaning - remove some unnecessary defined(SIMULATOR) checks by Dave Chapman · 17 years ago
  28. e1dd10d SWCODEC: Get rid of extra swap buffer and get back 512K of RAM or 100K if 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. by Michael Sevakis · 18 years ago
  29. aba6ca0 Fix resampling clicking as much as possible at the moment. 1) Upsampling 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. by Michael Sevakis · 18 years ago
  30. 0f5cb94 Big Patch adds primarily: Samplerate and format selection to recording for 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. by Michael Sevakis · 18 years ago
