Abstract

This sound conversion method includes: providing, to a trained model in which sound-quality designation data has been set, first acoustic-characteristic data of an input sound signal and pitch designation data based on the input sound signal; and acquiring, from the trained model, second acoustic-characteristic data for generating a conversion sound signal having sound quality which is in accordance with the sound-quality designation data. The trained model outputs the second acoustic-characteristic data by using the first acoustic-characteristic data and the pitch designation data. The pitch designation data indicates a pitch obtained by adjusting the pitch of the input sound signal on the basis of the relationship between: the pitch of a target sound signal which is the target for determining the amount of pitch adjustment; and the register which is associated with the sound-quality designation data.

Abstract

This sound generation system comprises: a control data string acquisition unit 30 that acquires a first control data string X representing features of a string of notes and a second control data string Y representing features of text corresponding to the string of notes; and a sound data string generation unit 33 that processes the first control data string X and the second control data string Y using a trained generation model Mb, thereby generating a sound data string Z representing musical instrument sounds of a string of notes having sound characteristics corresponding to the features of the text represented by the second control data string Y.

Abstract

Provided is a sound signal processing method in which, in response to sound signals of a plurality of channels, the level of the sound signal of each of the plurality of channels is adjusted, the sound signals of the plurality of channels after the adjusting are mixed, and a sound signal after the mixing is output. A first acoustic feature amount of the sound signal after the mixing is acquired, a target second acoustic feature amount is acquired, and the gain of each of the channels during the level adjustment is determined on the basis of the first acoustic feature amount and the second acoustic feature amount.
