Classification: CPC H  G | IPC G  H

Claim 1:
2. The method of claim 1, wherein the at least one processor processes an input audio signal from the earpiece via a microphone sensor on the earpiece wherein the method further comprises:
including, in the execution, by the at least one processor, of the graphic user interface, a tuning profile optimized for lecture output within the plurality of tuning profiles in the second menu displayed in the graphic user interface;
altering the input signal in the frequency domain by the at least one processor by amplifying the input signal according to the tuning profile optimized for lecture output;
performing an inverse Fourier transform on the altered audio signal according to the tuning profile optimized for lecture output, to obtain an altered audio signal to be output to the earpiece or an external speaker in the time domain, by the at least one processor; and
transmitting the second altered audio signal in the time domain to the earpiece or external speaker by the at least one processor.
