2017-12-13T01:28:56+00:00

Purpose: A step in removing all voice references from playback code
and prelude to other changes.

talk/voice: Reduce the size of the commit buffer.

2014-02-02T18:40:39+00:00

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.

talk: Make talk_voice_required() local to talk.c

Do not include kernel.h in system.h.

2014-01-05T18:35:23+00:00

system.h doesn't need it on its own and this change makes it less
dependant on Rockbox internals.

Enable setting of global output samplerate on certain targets.

2013-07-06T02:22:04+00:00

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.

Argh, move a comment to the (now) proper location. :)

Have voice fire an event when it starts and stops playing.

2013-05-31T22:45:51+00:00

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.

Defined as another playback event rather than a new event class:
PLAYBACK_EVENT_VOICE_PLAYING

Fix FS#12743 - 'Data Abort' on USB connection

2012-09-11T04:39:53+00:00

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.

Get voice PCM queue indexes updating in right order...

2012-05-30T16:55:26+00:00

...from the compiled code standpoint anyway. frame_out was being
incremented before updating size...sometimes...depending on what
GCC was up to. This seems to help.
