Abstract

An audio mixer for mixing a plurality of audio tracks to a mixture signal has a semantic command interpreter for receiving a semantic mixing command and for deriving a plurality of mixing parameters for the plurality of audio tracks from the semantic mixing command; an audio track processor for processing the plurality of audio tracks in accordance with the plurality of mixing parameters; and an audio track combiner for combining the plurality of audio tracks processed by the audio track processor into the mixture signal. A corresponding method has: receiving a semantic mixing command; deriving a plurality of mixing parameters for the plurality of audio tracks from the semantic mixing command; processing the plurality of audio tracks in accordance with the plurality of mixing parameters; and combining the plurality of audio tracks resulting from the processing of the plurality of audio tracks to form the mixture signal.
