Linear array - calibration

• The array was mounted on a rotating table, outdoor • A Mackie HR24 loudspeaker was used • A set of 72 impulse responses was measured employing Aurora plugins under Adobe Audition (log sweep method) - the sound card controls the rotating table. • The inverse filters were designed with the local approach (separate inversion of the 16 on-axis responses, employing Aurora’s “Kirkeby4” plugin)
