Abstract
An apparatus may include a signal generation module for generating a signal to test a loudspeaker. The signal generating module may be configured to receive a plurality of inputs identifying parameters relating to a test signal for the loudspeaker, generate a plurality of narrowband signals based on the plurality of inputs, sum the narrowband signals together to produce a broadband test signal, and transmit the broadband test signal to the loudspeaker to generate sound based on the broadband test signal.
