Claim 8:
9. The system of claim 8, wherein the processed input audio signal is processed from the earpiece via a microphone sensor on the earpiece, wherein the system additionally comprises an external speaker connected to the at least one processor, and wherein the at least one processor is further configured to:
include 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;
alter the input signal in the frequency domain by amplifying the input signal according to the tuning profile optimized for lecture output or karaoke singing output or classical concert output, respectively, to the externally connected speaker, to produce a second altered signal;
perform 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; and
transmit the second altered audio signal in the time domain to the external speaker.
