The audio level of the media source.

Description

Real number

MUST NOT exist for video (this is audio only).

Represents the audio level of the media source.

The value is between 0..1 (linear), where 1.0 represents 0 dBov, 0 represents silence, and 0.5 represents approximately 6 dBSPL change in the sound pressure level from 0 dBov.

The audioLevel is averaged over some small interval, using the algorithm described under totalAudioEnergy. The interval used is implementation-defined.
