A method for compensating for a modal response of a listening room on an acoustic output, comprising transforming a left channel signal and a right channel signal to a mid channel signal and a side channel signal, applying a mid channel filter to the mid channel signal to provide a filtered mid channel signal, applying a side channel filter to the side channel signal to provide a filtered side channel signal, retransforming the filtered mid channel signal and the filtered side channel signal to a left channel output and a right channel output, applying the filtered left channel output to a first loudspeaker, and applying the filtered right channel output a second loudspeaker. The resulting filtering avoids applying filtering to musical signals that do not require correction due to the interaction (or lack thereof) between the signals (as a result of their correlation coefficient) and the listening room's resonant behavior. |
