Sound Analysis-Synthesis

Edit






The Sound Analysis & Synthesis team carries out research and development activity in sound analysis, transformation, and synthesis of sound signals.
Edit






The analysis of sounds includes methods enabling the permanent extraction or automatic structuring of diverse sorts of information given off by the signal, such as the fundamental frequency or the spectral evolution determining the pitch and timbre of a perceived sound.

Information outside what is strictly musical is also taken into consideration, notably concerning industrial acoustics, sound design and multimedia as well as the automatic indexing of recorded sounds. The methods used are based on signal processing, statistical analysis, learning techniques and deep learning, recognition techniques, but also on knowledge of auditory perception.

Techniques of transformation and synthesis are initially created to respond to the needs of musicians in the production of new sounds and new music.

A typical example of this is the computer synthesis of a virtual choir for an opera. However, the work is frequently applied to the fields of mobile telecommunications, video games, film, and virtual reality. Analysis and synthesis are based on the design of signal models (modeling the effects of sounds produced in terms of signals) as well as on models in the form of deep networks learned from large databases that are often generated or augmented using signal models. These models are realized in the form of libraries and software (Mac OS x, Windows and Linux), specifically designed for professional and non-professional users, musicians, but also sound engineers, acousticians, and enthusiasts.

Major Themes

  • Signal Models : processing with a vocoder
  • Sound Characterization, automatic indexing
  • Analysis, characterization and transformation of musical recordngs
  • Analysis, transformation and synthesis of the voice, conversion of speakers

Specialist Areas

Signal processing, statistics, information theory, learning techniques, form recognition, digital analysis, modeling.

AudioSculpt

included in your membership
AudioSculpt uses a graphical approach to “sculpt” (to modify) a sound file. After a phase of analysis, the user modifies the analysis’ result directly, using only a mouse to apply the desired changes to the sound. Several types of analysis of the spectral content are shown and the user can modify the sound several different ways.

The Snail-Absolute Tuning

for sale at Ircam
The Snail-Absolute Tuning is a frequency analyzer based on an original chromatic alignment representation. Compared to conventional analyzers, this representation provides a simple visualization of the active zones through light activation and organizes the arrangement of frequencies by notes on a tempered scale, tuned to a tuning fork.
