An application can request a raw stream that is completely untouched and perform its own signal processing. Raw mode specifies that there should not be any signal processing applied to the stream. The modes are summarized in the table shown below.

It is recommended that IHVs/OEMs utilize the new modes to add audio effects that optimize the audio signal to provide the best user experience. OEMs and IHVs can determine which modes they want to implement. Windows defines seven audio signal processing modes. Available Signal Processing ModesĪudio categories (selected by applications) are mapped to audio modes (defined by drivers). Drivers declare the supported audio signal processing modes for each device.
