Patent ID: 8422691

Claim:
An audio outputting device for switching a plurality of noise cancellation modes to perform noise cancellation on an audio signal, and acoustically reproducing and outputting the audio signal, said audio outputting device comprising: a storage section configured to store a plurality of filter coefficient sets and a plurality of equalizer characteristic parameters, wherein each filter coefficient set corresponds to the noise cancellation modes and wherein each equalizer characteristic parameter corresponds to the filter coefficient sets; a control section configured to, in response to changing noise cancellation performed on the audio signal from a first noise cancellation mode to a second noise cancellation mode, stop noise cancellation on said audio signal based on said first noise cancellation mode, select, from the storage section, a filter coefficient set corresponding to the second noise cancellation mode, generate, based on the selected filter coefficient set, a noise cancelling filter for performing noise cancellation in the second noise cancellation mode, output sound based on said audio signal unprocessed by either of said first noise cancellation mode and said second noise cancellation mode, perform noise cancellation on said audio signal based on the second noise cancellation mode via the noise cancelling filter after passage of a predetermined period of time, select, from the storage section, the equalizer characteristic parameter corresponding to the second noise mode filter coefficient set, and perform sound quality correction on the input audio signal based on the equalizer characteristic parameter.
