[Feature] Advances in sound analysis and synthesis for musical applications have led to more realistic emulations of natural sounds, as well as the potential for creating new instruments. In this article we review recent AES convention papers that exemplify some of the most interesting developments in this field, concentrating in particular on a series of papers on vocal or singing synthesis from the team at the Universitat Pompeu Fabra in Barcelona delivered at the AES 121st Convention last year in San Francisco. At the outset, however, we describe two nonvocal synthesis approaches: one that can be used to improve the versatility and efficiency of physical modeling and another that has been employed to resynthesize the sound of a Chinese instrument known as the ehru. At the end of the article we describe two systems for analyzing vocal performances and singing quality.
