The CHANT Project: From the Synthesis of the Singing Voice to Synthesis in General

The CHANT project was originally concerned with the analysis and synthesis of the singing voice. This work led to a complex program of voice synthesisby-rule: CHANT. This program was enriched with a constantly expanding software environment, consisting of both analysis and composition programs. In time, broader aims than the synthesis of the singing voice imposed themselves. These aims centered on the search for models of the processes involved in the production of musical sound. Our present… 
New Possibilities in Sound Analysis and Synthesis
In this presentation we exemplify the emergence of new possibilities in sound analysis and synthesis with three novel developments that have been done in the Analysis/Synthesis team at IRCAM. These
Realtime and accurate musical control of expression in singing synthesis
A full computer-based musical instrument allowing realtime synthesis of expressive singing voice and a first framework for voice quality control is developed.
Synthesis of the Singing Voice by Performance Sampling and Spectral Models
The paper presents a singing voice synthesizer, pointing out the main issues and complexities emerging along its design, especially in the areas of expression, spectral modeling and sonic space design.
Composing Sounds: Developing Tools for Refined Control of Timbre in Music
A way of playing back sounds is described, which provides a compromise between the safety of recorded tapes and the temporal flexibility of real time technology.
An overview of synthesis methods, control strategies and research in this field is given and future challenges include synthesizer models improvements, automatic estimation of model parameter values from recordings, learning techniques for automatic rule construction and gaining a better understanding of the technical, acoustical and interpretive aspects of the singing voice.
Musical Representation of Sound in Computer-Aided Composition: A Visual Programming Framework
A composition framework dedicated to electro-acoustic music and sound synthesis integrated in the OpenMusic computer-aided composition environment is presented and Temporal issues are also discussed and are the object of specific developments.
Evaluation of Singing Synthesis: Methodology and Case Study with Concatenative and Performative Systems
The methodology needed for quality assessment of singing synthesis systems is addressed, a case study using 2 systems with a total of 6 different configurations is reported on and automatic melodic modelling is preferred to gestural control for off-line synthesis.
A Score-to-singing voice synthesis System for the Greek Language
The quality of the produced voice is evidently improved, with naturalness and expressivity being ranked above 3 in average, with the possibility of generating Greek singing voice with the MBROLA synthesizer by making use of an already existing diphone database.
The Singing Tree : a novel interactive musical experience
The technical and artistic design of the Singing Tree is discussed, a novel interactive musical interface which responds to vocal input with real-time aural and visual feedback which provides a reward-oriented relationship between the sounds one makes and the generated music and video stream one experiences.
Localization, Characterization and Recognition of Singing Voices
A set of novel features computed on the temporal variations of the fundamental frequency of the sung melody, which capture long-term information related to the intonation of the singers, which is relevant to the style and the technique of the singer.

The use of analyis of natural sounds for synthesis, the use of speech and vocoder techniques, methods of artificial reverberation, theUse of discrete summation formulae for highly efficient synthesis, and the role of special-purpose hardware in digital music synthesis are discussed.
FORMES: Composition and Scheduling of Processes
Toward a solution to problems of complexity in computer music, an object-oriented programming environment called FORMES has been developed and implemented at IRCAM and supports a new language with original features for composition and scheduling of objects.
