Analysis and Transformation of Sound

The tools developed at IRCAM offer possibilities for sound manipulation, spectral analysis, and computer-assisted music creation. They integrate into major production environments and support both compositional practices and sound research as well as performance.

ASAP is a collection of audio plug-ins designed for creative sound transformation. By manipulating sound representations and synthesis parameters, users can generate new textures, modify the characteristics of an audio signal, or improve its sound rendering. The plug-ins also enable restoration and sound correction operations. Thanks to ARA2 integration, spectral transformations are directly embedded into the audio editing workflow for seamless interaction with digital audio workstations.

Partiels is an audio analysis application accompanied by a set of plug-ins that allow users to explore one or more audio files using Vamp plug-ins. The environment enables loading, visualizing, organizing, editing, and exporting analysis data as images or text files. The generated data can then be reused in various creative environments such as Max, Pure Data, OpenMusic, or Reaper, facilitating exchanges between analysis, composition, and sound processing.

MuBu (Multi-Buffer) is an environment dedicated to real-time and offline multimodal processing in Max. It allows audio, gesture, and multimedia data to be stored, synchronized, and analyzed within a single workspace. MuBu integrates tools for sound descriptor analysis, motion tracking, interactive machine learning, and advanced synthesis techniques such as granular, concatenative, and additive synthesis.

Based on concatenative synthesis principles, CataRT enables exploration of large sound corpora based on their analytical features. Users can intuitively navigate sound databases to compose, improvise, or design new sonic worlds.

These environments are used in many artistic and technological contexts: musical composition, digital arts, dance, interactive installations, live performance, sound design, and immersive audiovisual systems. They provide a privileged space for experimentation and for developing new relationships between analysis, gesture, sound, and creation.
