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, and wherein an external speaker is connected to the at least one processor, 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 or classical concert output or karaoke singing output within the plurality of tuning profiles 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 or karaoke singing output or classical concert output, respectively, to an externally connected speaker, producing a second altered signal;
performing an inverse Fourier transform on the second altered audio signal according to the associated tuning profile optimized for lecture output, classical concert output, or karaoke singing output, respectively to an externally connected speaker, to obtain an altered audio signal to be output to the 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 external speaker by the at least one processor.
