Реферат: One embodiment provides a computer-implemented method that includes extracting a low-frequency effects (LFE) channel signal of a LFE side chain channel from a multichannel, wherein the multichannel includes the LFE side chain channel, at least one non-LFE side chain channel and a main channel. A method may comprise obtaining a first output signal including at least one harmonic signal of the LFE channel signal by applying a first non-linear function (NLF) to which the LFE channel signal. A method may comprise rejecting a fundamental frequency of the LFE channel signal from the first output signal. A method may comprise distributing the first output signal to a second output signal of the non-LFE side chain channel by applying a proportional power-sum-based mix-in.
