A key that specifies the A side-chain of float 32 data that an audio unit provides for sending high-density parameter value control information, and uses no flags.

Declaration

var kAudioFormatParameterValueStream: AudioFormatID { get }

Discussion

An audio unit typically runs a parameter value stream at either:

  • The sample rate of the audio unit’s audio data.

  • An integer quotient such as a half or a third of the sample rate of the audio.

The mSampleRate field in the AudioStreamBasicDescription structure describes this relationship.
