Abstract: A system for and a method of controlling generation of a 3D audio stream are disclosed. The method comprises accessing an audio stream; determining a value of a feature associated with the audio stream; selecting one or more 3D control parameters from a set of 3D control parameters, the selecting being based on the value of the feature associated with the audio stream; and generating the 3D audio stream based on the selected one or more 3D control parameters. In some embodiments, the feature is a metric associated with a frequency distribution of correlations of the audio stream.

Abstract: A system for and a method of generating an audio image for use in rendering audio. The method comprises accessing an audio stream; accessing positional information, the positional information comprising a first position, a second position and a third position; and generating an audio image. In some embodiments, generating the audio image comprises generating, based on the audio stream, a first virtual wave front to be perceived by a listener as emanating from the first position; generating, based on the audio stream, a second virtual wave front to be perceived by the listener as emanating from the second position; and generating, based on the audio stream, a third virtual wave front to be perceived by the listener as emanating from the third position.
