Abstract (en)
[origin: EP3820161A1] The present technology relates to an audio signal processing device and method, an impulse response generation device and method, and a program that enable a desired phase characteristic to be obtained.The audio signal processing device includes an acquisition part that acquires an impulse response having a flat or substantially flat amplitude characteristic and a predetermined phase characteristic, and a phase characteristic convolution part that convolves the impulse response into an input audio signal. The present technology can be applied to an audio signal processing device and an impulse response generation device.
