The IAudioBass interface provides access to a hardware bass-level control. The client obtains a reference to the IAudioBass interface of a subunit by calling the IPart::Activate method with parameter refiid set to REFIID IID_IAudioBass. The call to IPart::Activate succeeds only if the subunit supports the IAudioBass interface. Only a subunit object that represents a hardware function for controlling the level of the bass frequencies in each channel will support this interface.
Inheritance
The IAudioBass interface inherits from the IPerChannelDbLevel interface.
