Abstract: One embodiment provides a computer-implemented method that includes implementing a customizable compressor for at least one sidechain processing associated with a loudspeaker. Machine learning is applied to automatically tune one or more parameters of the at least one sidechain processing. One or more channels are extracted, including a low-frequency effects (LFE) channel, for nonlinear signal synthesis. A proportional power-sum-based mix-in of an LFE sidechain channel is applied into a non-LFE sidechain. The LFE sidechain channel is maintained within a specified threshold of being level, before and after nonlinear signal synthesis.
