Claim 14:
15. An apparatus comprising:
a memory storing instructions; and
at least one processor executes the instructions including a process configured to:
implement a customizable compressor for at least one sidechain processing associated with a loudspeaker;
apply machine learning to automatically tune one or more parameters of the at least one sidechain processing;
extract one or more channels, including a low-frequency effects (LFE) channel, for nonlinear signal synthesis;
apply a LFE-root mean square (RMS) proportional summation, using an LFE function for a LFE sidechain channel, into non-LFE sidechain channels; and
maintain the LFE sidechain channel within a specified threshold of being level, before and after nonlinear signal synthesis.
