Claim 0:
1. A computer-implemented bass extension method comprising:
implementing a customizable compressor for at least one sidechain processing associated with a loudspeaker;
applying machine learning to automatically tune one or more parameters of the at least one sidechain processing;
extracting one or more channels, including a low-frequency effects (LFE) channel, for nonlinear signal synthesis;
applying a LFE-root mean square (RMS) proportional summation, using an LFE function for a LFE sidechain channel, into is one or more non-LFE sidechain channels; and
maintaining the LFE sidechain channel within a specified threshold of being level, before and after nonlinear signal synthesis.
