Abstract
An audio signal processing method includes obtaining an audio signal of a sound source, performing first filter processing on the audio signal to generate an imaginary sound source of a virtual space, performing second filter processing on the audio signal to adjust a tone of the imaginary sound source, and outputting an initial reflected sound control signal generated by using the audio signal on which the first filter processing and the second filter processing have been performed, in a first case where the first filter processing is performed before the second filter processing, the first filter processing is performed on the audio signal, and the second filter processing is performed on the audio signal on which the first filter processing has been performed, and in a second case where the second filter processing is performed before the first filter processing, the second filter processing is performed on the audio signal, and the first filter processing is performed on the audio signal on which the second filter processing has been performed.
