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 processor is further configured to:
include, in the plurality of tuning profiles in the graphic user interface, a tuning profile optimized for lecture output;
alter the input signal in the frequency domain by amplifying the input signal according to the tuning profile optimized for lecture output;
perform 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; and
transmit the second altered audio signal in the time domain to the earpiece or an external speaker.
