* talk/voice: Reduce the size of the commit buffer.Thomas Martitz2014-02-02
| | | | | | | | | The voice engine can now request more voice data during decoding, it does not require the entire clip to be available before start of decoding anymore. Therefore the commit buffer does not need to hold an entire voice clip anymore, and can be made greatly smaller. Change-Id: I3eca9026448e725b9b8d0dae1efca0ad185371da

* Enable setting of global output samplerate on certain targets.Michael Sevakis2013-07-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Replaces the NATIVE_FREQUENCY constant with a configurable frequency. The user may select 48000Hz if the hardware supports it. The default is still 44100Hz and the minimum is 44100Hz. The setting is located in the playback settings, under "Frequency". "Frequency" was duplicated in english.lang for now to avoid having to fix every .lang file for the moment and throwing everything out of sync because of the new play_frequency feature in features.txt. The next cleanup should combine it with the one included for recording and generalize the ID label. If the hardware doesn't support 48000Hz, no setting will be available. On particular hardware where very high rates are practical and desireable, the upper bound can be extended by patching. The PCM mixer can be configured to play at the full hardware frequency range. The DSP core can configure to the hardware minimum up to the maximum playback setting (some buffers must be reserved according to the maximum rate). If only 44100Hz is supported or possible on a given target for playback, using the DSP and mixer at other samperates is possible if the hardware offers them.

* Have voice fire an event when it starts and stops playing.Michael Sevakis2013-05-31
| | | | | | | | | | | Further decouples voice_thread.c from other playback areas. Also allows other audio sources, such as FM radio, to be attenuated when voice is playing by implementing a callback.

* Fix FS#12743 - 'Data Abort' on USB connectionThomas Martitz2012-09-11
| | | | | | | | | | Because a pointer was uninitialized the move_callback() corrupted memory by derefencing it and moving stuff to uninitialized value. This reverts part of 8bbd4d9, where the offending line was removed. I can only guess it was removed by accident. Change-Id: I83cee5b396cf3cc99b000e5284fac72fb8ca8db2
* Get voice PCM queue indexes updating in right order...Michael Sevakis2012-05-30

* Zero out voice buffer memory immediately after allocation.Michael Sevakis2012-05-17
| | | | | | | | | Can't wait for the voice thread to initialize it since it concievably could be moved before the voice thread actually does so and the move callback accesses data that must be first set up in the voice thread function. Change-Id: Ia0d09539854db85e132e09d26cb129f02f5d93ff

* Use buflib for the allocation of voice PCM resources.Michael Sevakis2012-05-02
| | | | | | | | | | | | | Buffers are not allocated and thread is not created until the first call where voice is required. Adds a different callback (sync_callback) to buflib so that other sorts of synchonization are possible, such as briefly locking-out the PCM callback for a buffer move. It's sort of a messy addition but it is needed so voice decoding won't have to be stopped when its buffer is moved. Change-Id: I4d4d8c35eed5dd15fb7ee7df9323af3d036e92b3

* Fundamentally rewrite much of the audio DSP.Michael Sevakis2012-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Creates a standard buffer passing, local data passing and messaging system for processing stages. Stages can be moved to their own source files to reduce clutter and ease assimilation of new ones. dsp.c becomes dsp_core.c which supports an engine and framework for effects. Formats and change notifications are passed along with the buffer so that they arrive at the correct time at each stage in the chain regardless of the internal delays of a particular one. Removes restrictions on the number of samples that can be processed at a time and it pays attention to destination buffer size restrictions without having to limit input count, which also allows pcmbuf to remain fuller and safely set its own buffer limits as it sees fit. There is no longer a need to query input/output counts given a certain number of input samples; just give it the sizes of the source and destination buffers. Works in harmony with stages that are not deterministic in terms of sample input/output ratio (like both resamplers but most notably the timestretch). As a result it fixes quirks with timestretch hanging up with certain settings and it now operates properly throughout its full settings range.

| | | | | | | | | Use generic void * and size_t and make mp3_play_data and its callback agree on types. Use mp3_play_callback_t instead of prototyping right in the function call (so it's not so messy to look at). Change doesn't appear to require plugin API version increment.

* Revise the PCM callback system after adding multichannel audio.Michael Sevakis2012-03-03
| | | | | | | | | | | | | | | | | | Additional status callback is added to pcm_play/rec_data instead of using a special function to set it. Status includes DMA error reporting to the status callback. Playback and recording callback become more alike except playback uses "const void **addr" (because the data should not be altered) and recording uses "void **addr". "const" is put in place throughout where appropriate. Most changes are fairly trivial. One that should be checked in particular because it isn't so much is telechips, if anyone cares to bother. PP5002 is not so trivial either but that tested as working.

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.
