Claim Text:
1. A method of emulating a sound of an audio apparatus by using a sound emulation apparatus, the method comprising: obtaining a first sample of an audio signal, the first sample being a sample of the audio signal at a first point of time at which the audio signal is obtained by the sound emulation apparatus; delaying the first sample by a sampling interval; obtaining a second sample of the audio signal, the second sample being a sample of the audio signal second point of time at which the audio signal is obtained by the sound emulation apparatus, the second point in lime being after the first point in time by the sampling interval; applying a first characteristic function mapping an input value of the first sample input to the audio apparatus to an output value of the first sample output by the audio apparatus to obtain a first harmonic signal and a second characteristic function mapping an input value of the second sample input to the audio apparatus to an output value of the second sample output by the audio apparatus to obtain a second harmonic signal; and adding the first harmonic signal and the second harmonic signal to generate an emulation sound of the audio apparatus.
