    摘要: There is provided an auditory sense correction device capable of adding favorable loudness characteristics to an output sound without depending on sound source characteristics of an audio signal even when a high-frequency band or a low-frequency band of the audio signal has already been subjected to loudness correction. The auditory sense correction device 1 includes: a loudness processing section 2 which applies loudness processing to audio signals on a frequency band basis, a gain calculation section 4 which calculates a level difference between a signal level of each frequency band and signal level of entire frequency band; and gain setting section 5 which applies a correction gain of each frequency band to the audio signal of each frequency band that has been subjected to loudness processing.

    摘要: A signal delay adjustment device for individually setting delay times of audio signals supplied to a plurality of speakers and individually delaying the audio signals supplied to the plurality of speakers with set delay times to adjust output timings of sounds among the plurality of speakers is configured to include a setting part to set a delay time applied to the audio signal for each speaker, and a delay part for individually delaying the audio signal to be supplied to the plurality of speakers based on the delay time set by the setting part. The delay part gradually changes the delay time to be applied to the audio signal over a predetermined time so that the delay time to be applied to the audio signal reaches the delay time set by the setting part over the predetermined time.

    摘要: An audio processor (1) includes a first filter coefficient calculator (31) that calculates a first filter coefficient so as to correspond to first gains for respective bands set by a user, a second filter coefficient calculator (32) that if values of third gains for respective bands of the first filter coefficient are greater than an absolute value of a second gain set by the user, calculates a second filter coefficient by limiting the values of the third gains for the respective bands to the amplitude value of the second gain, and a filtering unit (35) that filters an audio signal that has been transformed into a frequency-domain signal, using the second filter coefficient.

    摘要: A sound field measuring device (1) obtains frequency characteristics by collecting output sound outputted from a pair of speakers (101a, 101b) installed at a narrow interval. A low-pass filter (22a) extracts low-range components of a first measurement signal. A high-pass filter (22b) extracts mid/high-range components of a second measurement signal different from the first measurement signal. A combined signal generation unit (22c) generates a combined signal by combining the low-range components of the first measurement signal and the mid/high-range components of the second measurement signal. An external output unit (6) outputs the first measurement signal to an audio system (102). A microphone (7) collects the first measurement signal and the combined signal simultaneously outputted from the pair of speakers. A Fourier transform unit (13) obtains the frequency characteristics of a sound field by Fourier transforming the signals collected.
