Abstract (en)
An audio signal (14) is received as an input at an audio processor (12). The audio processor (12) processes the input audio signal (12) to provide an audio signal to be output (16) to a loudspeaker. The processing of the input audio signal (12) reduces the power of the input audio signal (12) at a resonant audio frequency and increases the power of the input audio signal (12) at at least some other audio frequencies other than the resonant audio frequency.
