Abstract

Many audio appliances feature capabilities for modifying audio signals, such as equalization, acoustic room effects, etc. However, these modification capabilities are always limited in the sense that they apply to the audio signal as a whole and not to a specific "audio object". We are proposing a scheme which enables modification of stereo panning and gain of specific objects inherent in a stereo signal. This capability is enabled (possibly stereo backwards compatibly) by adding a few kilobits of side information to the stereo signal. For generating the side information, the signals of the objects to be modified in the stereo signal are needed.
