Abstract
A speaker's output volume is increased by obtaining, from a memory, a frequency response curve associated with a speaker. A digital signal processor determines, according to the frequency response curve, a frequency range associated with the speaker's max output volume and designates the frequency range associated with the speaker's max output volume as the target frequency. The digital signal processor remaps in real-time an audio input signal to produce an audio output, from the speaker, in the target frequency.
