摘要： According to one embodiment, an acoustic correction apparatus includes an input module, a calculator, a divider, a converter, an extractor, a synthesizer, and a generator. The input module receives an audio signal propagated through a sound field. The calculator calculates an impulse response from the audio signal. The divider divides the impulse response into first and second impulse responses. The converter converts the first and second impulse responses into first and second frequency spectrums. The extractor specifies an amplitude component of the first frequency spectrum with a peak relatively higher than that of the amplitude component of the first frequency spectrum, and extracts the peak as a resonance component. The synthesizer synthesizes a first property and a second property for attenuating the resonance component. The generator generates a correction filter for performing correction to obtain the synthesized property.

摘要： According to one embodiment, an AV device comprises a receiving section, a processing section, a storage section and a control section. The receiving section receives a digital voice signal. The processing section applies a predetermined signal processing operation to the digital voice signal received by the receiving section. The storage section stores information indicating time required for the signal processing operation at the processing section, and when a voice has been set in a mute state, stores the information indicating the time required for the signal processing operation by the processing section which is rewritten into a value that cannot be taken in general. The control section outputs information stored in the storage section upon an external request. Other embodiments are also described.
