Sound
|
|
=====
|
|
|
|
The *Sound* page contains settings related to the emulated machine's audio hardware.
|
|
|
|
Sound card
|
|
----------
|
|
|
|
Sound card to emulate. Only cards supported by the machine's expansion buses will be listed. On machines equipped with an onboard sound chip, the *Internal* option enables the onboard sound.
|
|
|
|
The *Configure* button opens a new window with settings specific to the selected sound card, such as the I/O ports, IRQ and DMA channels for ISA cards.
|
|
|
|
MIDI Out Device
|
|
---------------
|
|
|
|
Device to output MIDI music to, for sound cards equipped with an external MIDI output.
|
|
|
|
* **None:** don't output MIDI music.
|
|
* **FluidSynth:** a software soundfont synthesizer. The FluidSynth library file must be present in the 86Box directory, and a soundfont must be configured.
|
|
* **Roland MT-32 Emulation:** emulate a Roland MT-32 synthesizer device. Emulation is provided by the `Munt <http://munt.sourceforge.net>`_ library.
|
|
* **Roland CM-32L Emulation:** same as above, but emulating a Roland CM-32L instead.
|
|
* **System MIDI:** output to a (configurable) host MIDI device, such as the Windows software synthesizer or a USB MIDI adapter.
|
|
|
|
The *Configure* button opens a new window with settings specific to the selected output device.
|
|
|
|
MIDI In Device
|
|
--------------
|
|
|
|
Device to receive MIDI music from, for sound cards equipped with an external MIDI input.
|
|
|
|
* **None:** don't receive MIDI music.
|
|
* **System MIDI:** receive from a (configurable) host MIDI device, such as a USB MIDI adapter.
|
|
|
|
The *Configure* button opens a new window with settings specific to the selected input device.
|
|
|
|
Standalone MPU-401
|
|
------------------
|
|
|
|
Emulate a standalone **Roland MIDI Processing Unit** ISA card, which allows for MIDI input and output without a MPU-401-equipped sound card.
|
|
|
|
The I/O port and IRQ can be configured through the *Configure* button.
|
|
|
|
Innovation SSI-2001
|
|
-------------------
|
|
|
|
Emulate the **Innovation SSI-2001** ISA sound card, based on the MOS Technology 6581 chip (commonly known as the Commodore SID) and supported by a limited number of games.
|
|
|
|
SID emulation is provided by the `reSID <http://www.zimmers.net/anonftp/pub/cbm/crossplatform/emulators/resid/>`_ library.
|
|
|
|
CMS / Game Blaster
|
|
------------------
|
|
|
|
Emulate the **Creative Music System** or **Game Blaster** ISA sound card, based on dual Philips SAA1099 sound chips and supported by some games.
|
|
|
|
Gravis Ultrasound
|
|
-----------------
|
|
|
|
Emulate the **Gravis UltraSound** ISA sound card.
|
|
|
|
The type of UltraSound to emulate (Classic or MAX), I/O port and amount of onboard RAM can be configured through the *Configure* button.
|
|
|
|
Use FLOAT32 sound
|
|
-----------------
|
|
|
|
Use the 32-bit floating point (instead of 16-bit integer) data type for audio output, which is less prone to clipping. Try disabling this option if you're getting no audio output at all.
