Audio Subsystem
The crystal audio subsystem provides 16-bit stereo audio with
high-quality FM music synthesis using four operators per voice. It
can record, compress, and play back voice, sound, and music with
built-in mixer controls. It consists of an embedded microprocessor,
16-bit stereo, 20-voice FM music synthesizer (or 18 simultaneous
4-operator voices), MIDI serial port compatible MPU401 UART mode,
DMA control, and ISA bus interface logic.
The AudioDrive provides the computer with the following audio
features:
High-quality audio (44.1-kHz MPC-2 16-bit audio)
General MIDI compatible, 32-voice wave table synthesizer
Sound Blaster support
