Claim 0:
1. A sound synthesizing method of synthesizing an audio signal from music data, the method comprising:
generating a first model, which is a first neural network, trained using first training data to estimate a series of fluctuations for each unit period;
generating a second model, which is a second neural network, trained using second training data to estimate a series of features for each unit period;
obtaining from the music data:
a first series of control data of a target sound to be synthesized; and
a second series of control data of the target sound to be synthesized;
generating a series of fluctuations, which is a dynamic component that fluctuates with time, of the target sound based on the first series of control data of the target sound to be synthesized obtained from the music data with the first model; and
generating a series of features, which indicate a series of at least one of pitches, amplitudes, or tones, of the target sound based on the second series of control data of the target sound obtained from the music data and the generated series of fluctuations of the target sound with the second model; and
generating the audio signal representing a waveform of the target sound based on the generated series of features.
