Abstract:
A howling suppressing apparatus includes: a detecting unit configured to detect howling of input audio signals; a plurality of filters configured to apply a filter process sequentially to the audio signals to be output; and a setting unit configured to set a filter coefficient for suppressing the howling detected by the detecting unit for a filter among the plurality of filters, in which filter no filter coefficient for suppressing howling is set, and set a filter coefficient for suppressing the howling detected by the detecting unit for any one of the plurality of filters, if filter coefficients for suppressing howling are set in all of the plurality of filters, based on the detection result from the detecting unit.
