Audio Framework

v1.10

Description:

Audio Framework is an abstraction layer that allows audio codec drivers to integrate with multiple target platforms separating Generic Wavedev2 and the actual hardware.

It provides automatic configuration facilities, such as automatic clocking, bus capability matching and power management, as well as a standard interface to control audio codecs through the Control Framework.
