摘要:
An audio signal compensation device includes: a signal processor configured to perform filtering on an input audio signal; a filter coefficients storage module configured to store a plurality of filter coefficients; a user interface configured to provide options for a determination of filter coefficients to a user and to obtain a selection result from the user; and a filter coefficients determining module configured to determine a set of filter coefficients among the plurality of filter coefficients based on the selection result. The options for the determination of filter coefficients are produced by selecting a first filter coefficient and a second filter coefficient from the plurality of filter coefficients, the first filter coefficient corresponding to a first characteristic quantity of external auditory canal characteristics, the second filter coefficient corresponding to a second characteristic quantity of the external auditory canal characteristics which is predicted based on the first characteristic quantity.
