Abstract

A system and method are disclosed for emulating a frequency modulation sound chip with minimal hardware and utilizing the excess capacity of current computer systems. In one embodiment, the frequency modulation emulation apparatus includes a frequency modulation emulator suitable to communicate with a computer system. The frequency modulation emulator provides an addressable memory space, substantially similar to an emulated addressable memory space of the emulated frequency modulation sound chip, such that a frequency modulation application implemented on the computer system can communicate with the frequency modulation emulator. The emulator chip receives audio data through the addressable memory space from the frequency modulation application and, the frequency modulation application is unaware that the frequency modulation emulator is receiving the audio data rather than the emulated frequency modulation sound chip. A frequency modulation generator is implemented on the computer system. The frequency modulation generator receives the audio data from the frequency modulation generator. The frequency modulation generator processes the audio data to produce an audio signal in a manner that is substantially similar to the operation of the emulated frequency modulation sound chip. Thus, minimal hardware is used to emulate a frequency modulation sound chip, and utilizing the excess capacity of current computer systems.
