Q. How does PC sound work on the Risc PC 486 Card?
The Sound Blaster card has become established as the de facto standard for sound output for games and CD ROMs in the PC world. PC sound capability on Risc PC is effected by emulating the Sound Blaster hardware within the RISC OS domain.
Sound from a PC application can then be routed through to the 16-bit Sound hardware in the Risc PC. (The 16-bit Sound hardware comes built into the motherboard of the new range of Risc PCs and is available as the 16-bit Sound Upgrade for earlier Risc PCs.).
The Sound Blaster emulation consists essentially of MIDI and sound samples (primarily used by CD ROMs such as Encarta) and is supplied as part of the 16-bit Sound Software upgrade from ESP or Aleph One.
Sound Blaster drivers are needed in the PC domain to drive the Sound Blaster emulation: either 8-bit drivers which come with Windows or 16-bit drivers which have been developed by Acorn and supplied as part of the 16-bit Sound Software application available from ESP or Aleph One in Q4.
The 16-bit Sound Software application from ESP and Aleph One also includes a MIDI synthesis capability in software for the RISC OS domain and RISC OS sound drivers for the 16-bit Sound Card, which can be used by existing RISC OS MIDI sound applications like Maestro, Rhapsody and Sibelius, and multimedia applications such as ARPlayer.
