- 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.
The code currently only works with the SDL sound output module and at 44100 Hz,
with 16 bit stereo signed little endian format. FM volume control and
save/restore support are not implemented yet. The legacy code for generating
MIDI notes still works and will be removed when mixing support is implemented
in all sound modules.
- Define new structure bx_pcm_param_t and use it as a parameter for the method
sendwavepacket(). The method startwavepacket() is now called from
sendwavepacket() in case of a parameter change (temporary solution).
- soundsdl: Replaced waveready() call by some more accurate code for buffer
space check in sendwavepacket().
- soundsdl: Moved code for reading from audio buffer to a new function.
- soundsdl: Temporarily increase the audio buffer size.
- Preparing the SB16 code for the OPL emulation port from DOSBox.
- Reworked wave callback code to support 2 input sources (no mixing yet).
- Fixed SDL sound output.
- Beep generator fixes.
- Prepared the SB16 code for FM OPL output support (to be ported from DOSBox).
- Renamed wavedata callback type.
- Handle sample rate in the beep generator (TODO: handle data format).
- Don't call waveready() in the SB16 code.
- Attempt to fix SDL2 wave output using SDL_LockAudio() / SDL_UnlockAudio().
- SDL specific code in the beep thread no longer needed.
- Increment timer counter before checking for overflow.
- Implemented ISA bus delay in the pc_system code and use it for the SB16.
This makes OPL chip detection work at ips values > 4 Mips.
TODO: OPL chip should use wave output instead of MIDI (maybe port from DOSBox).
TODO: Use isa_bus_delay() for other legacy devices if required.
usb device plugins. Loading the plugin means that the user wants to enable it.
Disabling the device on the command line and in the config interface is still
possible.
- ES1370: implemented CODEC registers (AK4531 mixer) and wave volume control
- Moved wave volume application code to new method pcm_apply_volume() and use
it for both soundcards
- TODO: stereo support
- SB16: log file name now also available as a runtime option
- SB16: changed order of the runtime options and minor other changes
- ES1370: changed the "wavemode" parameter type to bx_param_enum_c and set up
more accurate dependencies (similar to SB16)
- ES1370: wave mode and file name now available as a runtime option
- If the runtime flag of a bx_list_c object is set, all it's items are set up
as runtime options.
- Set the runtime parameter for all top-level runtime-only lists. Setting up
each single parameter is no longer needed.
- Always initialize the lowlevel sound driver (for wave input / recording)
- Wave input (recording) is now independent from the wave output mode
- Changed the "wavemode" parameter type to bx_param_enum_c and set up more
accurate dependencies
- Minor related changes
- ALSA stuff moved from soundlnx.* to new soundalsa.* files
- SB16 / ES1370: including specific sound driver headers not necessary
- updated dependencies
- added parameters 'wavemode' and 'wavefile' to the 'es1370' option
- ES1370: added new method sendwavepacket() (similar to SB16)
- moved VOC file methods from sb16.cc to soundmod.cc and added macros for them
- SB16: minor fixes
- added 'wavein' parameter to specify the wave input device if necessary
- if 'wavein' is not set, Bochs uses the 'waveout' value for input, too
- SB16: the 'wave' parameter is now only used to specify the filename (mode 2 or 3)
- TODO: implement 'wavemode' feature for ES1370 similar to SB16
- added 'sound' option to select the driver and the wave output device
(see bochsrc sample for details)
- the wave device option of sb16 and es1370 is now only used to set up the
wave input device (if necessary)
- cleaned up the speaker code to initialize the 'sound' case correctly
- memory: initialize ISA and PCI ROM variables in init_memory()
- sb16: remove items from runtime menu in destructor
- gui debugger: show dialog contents (TODO: fix remaining display issues)
- TODO: fix deadlock in bx_wx_gui::handle_events()
- use this feature for floppy read and write operations. This does not mean that
the floppy now works faster than realtime, but it reduces the number of DMA
calls from the CPU.
- removed outdated file: patch.fast-dma-cbothamy
- TODO: implement this feature in the SB16 (8 and 16 bit)
- SIM->opt_plugin_ctrl() now can be used to verify the optional plugin
configuration when using the plugin name "*". The 'load' value 1 makes
sure that all plugins with the value 1 are loaded. The 'load' value 0
unloads all plugin with the value 0 (marked for removal).
- add the default set of plugins to the 'plugin_ctrl' list and load all these
pre-defined optional plugins before parsing the configuration.
- special wx case: verify plugin configuration before showing the plugin
control dialog and before initialising hardware.
- device plugins that have been loaded, but not configured now set their
plugin control value to 0. Added the plugin unload check before signalling reset.
- TODO #1: update MSVC workspace files
- TODO #2: these 'device classes' could be moved to subdirectories, too:
- pci (when we have more than one chipset)
- display (when we have one more device and vga / cirrus cleaned up)
