- Added the capability to load up to 4 sound drivers and added methods to
get pointers to the waveout, wavein and midiout services of a driver.
- Rewrite of the SB16 midi file output code. In midimode 2 and 3 the midiout
service of the 'file' driver is used. Removed obsolete midi file handling.
- Re-implemented the closemidioutput() method to make runtime changes of the
midi setup work with the new code.
- waveout: added support for RIFF WAVE format and raw output. The formats
'voc' and 'wav' are detected by file extension, raw output is used otherwise.
- midiout: added support for raw midi output (no header, no deltatime).
The 'mid' format is detected by file extension, raw output is used otherwise.
- Added 'midiout' parameter to the global sound option to specify the device
if necessary. The related SB16 parameter now only specifies the output file.
- TODO: Rewrite of the sound configuration and output code to support dual
output (device and file).
- New code is based on the dummy sound driver and file output code from SB16.
- The midiout feature supports the MIDI file format.
- The waveout feature currently only supports the VOC format.
TODO:
- Add support for a more detailed sound configuration (waveout to device,
midiout to a file.
- The waveout feature should support WAV and RAW file formats.
- Move VOC file handling from soundmod.cc to soundfile.cc.
- Finally remove file handling code from sound devices.
creates the object and returns a pointer to it. TODO: Rewrite of the sound
configuration to support a more detailed setup (e.g. waveout with alsa,
dummy wavein, midiout to a file).
creates the object and returns a pointer to it. TODO: The wavein and midiout
components should also move to separate classes. When finished, it should be
possible to configure the sound support more detailed (e.g. waveout with sdl,
midiout with alsa and the dummy driver for wavein). Creating a separate
module for the output to file(s) is also possible.
'alsa'. Cleaned up the code a little bit.
TODO #1: Implement mixer thread support in the OSX sound driver.
TODO #2: Code cleanups in the Bochs sound code.
TODO #3: Resampling support and improvements in the wave recording code.
- removed disabled code for the sndPlaySound() function.
- removed now obsolete buffer ring for wave output.
- The new mothod waveout() is driven by the mixer thread. For the best results
you need to disable the 'realtime' sychronization and to find out a usable
IPS vaöue. The mixer also polls data from the speaker beep generator and
the OPL3 FM generator.
- TODO: Code cleanup in soundwin.cc, implementation in other sound modules.
- soundlow: prepared code for 2 pcm parameter sets:
emulated: requested by sendwavepacket()
real: used for the sound output
- soundsdl: startwaveplayback() rewritten to set_pcm_data().
- soundmod: some beep init code fixes.
- OPL3: Added support to change the samplerate of the generator.
- SDL sound: convert wave packet to 16 Bit signed stereo format.
- Increased the maximum size of a single wave packet for playbck/recording.
- Beep thread now only started one per simulation.
- Added some more multithreading macros and use them in rfb, vncsrv and soundmod.
- TODO: implement mixer thread and remove beep thread.
