摘要: In a method of coding plurality audio signals, the left and right basic channel as well central are combined by joint stereo so to obtain jointly coded signal, which is decoded provide simulated signals. The signals two surround channels matricization means compatibility matrix form compatible suitable for decoding existing decoders. order avoid audible disturbances caused excessive energy contents would occur if were carried out prior carrying matricization, or dynamically weighted dynamic correction factor in such way that approximated with regard their be obtained matricized directly.
