Abstract:
1. A method for generating light control parameters for controlling light in response to an audio signal (A), the method comprising the steps of: analyzing the audio signal (A) in order to determine a temporal evolution of semantic content of the audio signal (A) and spatial properties of the audio signal (A), wherein said semantic content is determined based on at least one low level feature that is extracted from the audio signal (A), said low level features being selected from the group consisting of timbre and tonality; and generating separate light control parameters for controlling spatially positioned light sources according to the spatial properties of the audio signal (A), wherein the separate light control parameters are generated according to the temporal evolution of semantic content of the audio signal (A), wherein said method further comprises the step of: determining semantically distinct temporal sections of a sequence of the audio signal (A), and wherein the light control parameters are generated to reflect these sections of the audio signal (A).
