  1. 2acc0ac Updated our source code header to explicitly mention that we are GPL v2 or by Daniel Stenberg · 16 years ago
  2. 405e90e PCM buffer muting doesn't seem benificial for wm8978 so turn it off. by Michael Sevakis · 16 years ago
  3. 7f4a713 Removed unused function get_pcmbuf_descsize from pcmbuf.c by Bertrik Sikken · 16 years ago
  4. b24ed65 Simplify pcmbuf_beep() a little, should be no functional change but it seems to mysteriously change the PortalPlayer 'keyclick beep of death' problem into a 'barely-there keyclick' problem. by Steve Bavin · 17 years ago
  5. 21870cf Fixes FS#8651 (noise and/or crash while crossfading). Latest ARM-asm submit for dsp showed we had a possible alignment issue with pcm-buffer when using crossfade. by Andree Buschmann · 17 years ago
  6. 135cc75 Revert my earlier const madness, we'll keep the parameter lists simple. by Steve Bavin · 17 years ago
  7. c9df8fd The const police raid playback.c, should be no change to behaviour. by Steve Bavin · 17 years ago
  8. 27cf677 Add a complete priority inheritance implementation to the scheduler (all mutex ownership and queue_send calls are inheritable). Priorities are differential so that dispatch depends on the runnable range of priorities. Codec priority can therefore be raised in small steps (pcmbuf updated to enable). Simplify the kernel functions to ease implementation and use the same kernel.c for both sim and target (I'm tired of maintaining two ;_). 1) Not sure if a minor audio break at first buffering issue will exist on large-sector disks (the main mutex speed issue was genuinely resolved earlier). At this point it's best dealt with at the buffering level. It seems a larger filechunk could be used again. 2) Perhaps 64-bit sims will have some minor issues (finicky) but a backroll of the code of concern there is a 5-minute job. All kernel objects become incompatible so a full rebuild and update is needed. by Michael Sevakis · 17 years ago
  9. ca55f13 Fix typo. by Nicolas Pennequin · 17 years ago
  10. 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
  11. 88c4748 Couple more tiny changes. :) by Michael Sevakis · 17 years ago
  12. 18330a0 Missed a couple changes by Michael Sevakis · 17 years ago
  13. 5398125 Use sized data types for audio data in the pcm buffer. Speed up the clipping routine. by Michael Sevakis · 17 years ago
  14. 6077e5b Unify PCM interface just above the hardware driver level for all targets 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. by Michael Sevakis · 17 years ago
  15. 3bec38e SWCODEC: Get rid of unneeded pcm_mute() calls. Leave the only ones that seem to be needed for WM codecs. by Michael Sevakis · 17 years ago
  16. 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
  17. 938593b Put the sims in their place. by Michael Sevakis · 18 years ago
  18. b425de7 Fix problem with recording screen creep and bag a bigfoot. Voice clips 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. by Michael Sevakis · 18 years ago
  19. 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
  20. 2597a13 Next round of static'ing and related fixes. by Jens Arnold · 18 years ago
  21. e3b0937 Priority overriding was not working correctly. by Miika Pekkarinen · 18 years ago
  22. bf65676 Removed muting from pcm buffer during starts, stops and pauses for tlv320 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. by Michael Sevakis · 18 years ago
  23. 5dd0775 Calculation was wrong in pcmbuf_is_same_size such that is would almost certainly return false. by Michael Sevakis · 18 years ago
  24. 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

  53. 0744e76 Ensure that the buffer doesn't get out of sync on rebuffer track changes. Remove the concept of pcmuf_boost_mode as it doesn't seem necessary, and adds an unnecessary way for the CPU to stay boosted. by Brandon Low · 18 years ago

  56. 33a62e8 More work on swcodec. No significant pcmbuf functions are called from the audio thread now. Do not be surprised if seek or skip behavior gets weird after this, but it Works for Me (TM), and is a significant step in the right direction. by Brandon Low · 19 years ago
  57. 8bdd92b New 'Track Skip Only' option for Crossfading; crossfading is disabled except for manual track changes. NOTE: If you were using 'Always' mode previously, check again after updating: you'll now be in the new 'Track Skip Only' mode. by Zakk Roberts · 19 years ago
