Some audio interfaces are ASIO-exclusive, such as SSL 2+, Presonus Quantum 2626, Focusrite Red 8Pre, and more - such devices will not work with WASAPI drivers. Most external audio devices support both WASAPI and ASIO drivers, although some are limited to running a single driver at a time. Most external audio interfaces will include a WDM driver (driver framework developed by Microsoft for Windows) that allows communication with the operating system and other applications, providing support for plug-and-play functionality, power management, and other system features via the Windows Audio Engine. Most of the built-in audio solutions such as headphone ports and motherboard audio employ WASAPI drivers by default (WDM, DirectSound, or MME). SoundID Reference drivers receive the audio signal, calibrate and send the corrected audio signal to the output device driver of the designated hardware device: Setting up with the driver types in SoundID ReferenceĪudio drivers are software components that enable communication between the operating system and the audio hardware installed in a computer.
