1. The Ecosystem: Where ACT Fits

To understand ACT, one must first understand the hardware it controls. Qualcomm’s Hexagon DSP (Digital Signal Processor) is the engine responsible for audio processing on Snapdragon platforms. Unlike the CPU, which handles general computing, the DSP is specialized for math-heavy signal processing.
