| Abstract: | A method based on targeted transfer function is developed to fix the reproduction characteristics of loudspeaker. The fixing inverse filter is developed, and the regularization factor is incorporated to prevent too large frequency gain. The effect on fixing results brought by filter lengths is also discussed. For such method is based on needed targeted transfer function, it can be used in various fixing needs or applications. |
