Methods for encoding an audio signal, and to decode a signal coded audio encoder to encode an audio signal, apparatus to provide an audio signal.The coded audio signal, storage medium, and decoder to decode a coded audio signal.In summary, this application describes a psycho acoustically driven parametric description of spatial attributes of audio signals of multiple channels.This parametric description allows strong reductions of bit rate in audio encoders, since only a monaural signal must be transmitted.Combined with parameters (quantised) describing the spatial properties of the signal. The decoder can form the original quantity of audio channels by applying the spatial parameters.For stereo audio quality next CD, a bit rate associated with these parameters space of 10 kbit / s or less.It seems sufficient to reproduce the spatial impression correct at the end of reception.
