Abstract:
A method for compensating for acoustic influence of a listening room on an acoustic output from an audio system including at least a left and a right loudspeaker, the method comprising determining a left frequency response and a right frequency response, designing left and right compensation filters, and during playback applying the left and right filters to left and right input signals. The method further includes determining mono and side responses and designing mono and side compensation filters, and, during playback, applying the mono compensation filter to a mono signal based on the left and right input signals, and applying the side compensation filter to a side signal based on the left and right input signals. The filters are thus combined to provide left and right output signals which have been left/right filtered and mono/side filtered.

Claim (Index 26):
The method according to  claim 25 , wherein the smoothing is performed by:\n determining a number of peaks per octave in the response, for a portion of the response where the number of peaks per octave is below a first threshold, smoothing the response with a first smoothing width, for a portion of the response where the number of peaks per octave is above a second threshold, smoothing the response with a second smoothing width, wherein said second threshold is greater than said first threshold and said second smoothing width is wider than said first smoothing width, and for a portion of the response where the number of peaks per octave is between the first and second thresholds, smoothing with an intermediate smoothing width.
