High-Level Emulation (HLE) is a technique used to emulate hardware components, such as audio chips, by mimicking their behavior at a high level. Unlike low-level emulation, which focuses on replicating the hardware's internal workings, HLE focuses on replicating the chip's external behavior, allowing for faster and more efficient emulation.
