Partiels – audio analysis and feature extraction

Partiels is an audio analysis application developed at IRCAM for exploring the characteristics of recorded sound. It provides a graphical environment for examining audio signals and investigating information extracted through specialised analysis algorithms.

The application supports multiple audio files and channels, making it suitable for comparing recordings and studying complex acoustic material. Analysis results can be presented as spectrograms, lines, markers and other visual representations.

Partiels uses Vamp plugins to extend its analytical capabilities. These make it possible to investigate spectral characteristics, pitch, transients and other features, while the resulting data can be edited, organised and exported for use in external software.

This is free and open source software.
