Loudspeaker and Room Correction Using Digital Signal Processing
This paper concerns digital signal processing techniques used to equalize loudspeakers and correction of room effects well away from the speaker itself. Measured results for linear and minimum phase corrections are presented. Various algorithms for calculating digital equalization filters are discussed, including techniques to limit the length of the digital filter. Some of the problems inherent in the correction of room acoustics are highlighted and some of the perceived effects after correction are outlined.
