• Target: The Capcom QSound hardware (used in games like Street Fighter Alpha, Dungeons & Dragons: Shadow over Mystara, and War Gods).
• Function: This feature allows the emulator to produce accurate audio without requiring the original DSP (Digital Signal Processor) microcode or cycle-accurate simulation of the underlying chips.
• Mechanism: Instead of simulating how the electricity moves through the QSound DSP chip (Low-Level Emulation), the emulator intercepts the commands sent by the game to the sound chip and processes them using the host computer's CPU.
