Abstract: An apparatus including circuitry configured for: receiving at least two audio signals; determining at least one lower frequency effect parameter based on the at least two audio signals; determining at least one transport audio signal based on the at least two audio signals; controlling a transmission/storage of the at least one transport audio signal and the at least one lower frequency effect information such that a rendering based on the at least one transport audio signal and the at least one lower frequency effect information enables a determination of at least one low frequency effect channel.
