Abstract:
A method for generating digital filters for equalizing a loudspeaker, comprising the steps of:providing first digital data for a tolerance range for a target response curve of sound level versus frequency for said loudspeaker; providing second digital data for an actual response curve of sound level versus frequency for said loudspeaker; comparing said first digital data to said second digital data and determining whether said actual response curve is within said tolerance range; and if said actual response curve is not within said tolerance range, iteratively generating digital audio filters, generating modified data relating to the response of said loudspeaker modified by said digital audio filters, and automatically optimizing the frequency, amplitude and bandwidth of said digital audio filters until said modified data is within said tolerance range or a predetermined limit on the number of digital audio filters has been reached, whichever occurs first.
