Abstract
A system and method automates the tuning of one or more multiband compressors or multiband limiters to minimize loudspeaker distortion. The system and method render one or more test loudspeaker signals that vary in frequency and in amplitude out of a loudspeaker and records the responses of the loudspeaker at a microphone. The system and method measure a distortion of the loudspeaker, relative to a frequency and an amplitude, with respect to the one or more test loudspeaker signals and a microphone signal and calculate tunable parameters of the multiband compressor that includes cutoff frequencies in response to the measured distortion.
