A loudspeaker response model using tuneable approximate piecewise linear regression

A practical loudspeaker frequency response interpolation model is developed using a tuneable approximate piecewise linear regression (TAPLR) model that can provide a complete amplitude and phase response over the full frequency range of the loudspeaker. This is achieved by taking a finite number of standard one-twelfth octave frequency amplitude measurements at a one meter distance in front of the loudspeaker. The Hilbert transform can be used to compute corresponding phase response from the amplitude response.
