Instance Codec Properties
Properties that can be set or read on an instance of the audio codec.
Overview
These properties are used with the AudioCodecGetProperty(_:_:_:_:) and AudioCodecSetProperty(_:_:_:_:) functions.
These properties are dependent on the codec’s current state. A property may be read/write or read only, depending on the data format of the codec.
These properties may have different values depending on whether the codec is in the initialized state. You can set writable properties only when the codec is not initialized. All properties can be read at any time the codec is open.
