Claim 7:
8. A non-transitory processor-readable medium that includes a program that when executed by a processor performs bass extension for a loudspeaker, comprising:
implementing, by the processor, a customizable compressor for at least one sidechain processing associated with the loudspeaker;
applying, by the processor, machine learning to automatically tune one or more parameters of the at least one sidechain processing;
extracting, by the processor, one or more channels, including a low-frequency effects (LFE) channel, for nonlinear signal synthesis;
applying, by the processor, a LFE-root mean square (RMS) proportional summation, using an LFE function for a LFE sidechain channel, into non-LFE sidechain channels; and
maintaining, by the processor, the LFE sidechain channel within a specified threshold of being level, before and after nonlinear signal synthesis.
