Applications and Examples

Here is a description of the project he sent:

Pareto is a set of patches made for the software Open Music from IRCAM, mainly done for the analysis of the oral tradition music.

It offers three functionalities:

1) To transcribe an acoustic signal of the fundamental (from Diphone, Audiosculpt, Spears, etc..) into symbolic musical information (in midicents or in musical notation approximated in half-tone, third of tone, quarter-tone, eight of tone, ore more)

2) To propose statistical tools (curves, most present frequencies, mobile average, etc..) to help to determine the scale of the musical signal.

3) To change or adjust the musical signal with new hypothesis (new scale, or discretisation, etc..), and then to make similar changes of the scale on the acoustic signal itself (through microtransposition on SVP), one of the goal being to be able to propose an "acoustic" analysis to the musicians, and to and check it with them without verbalizing it.

This Program has been computed for a CNRS/IRCAM mission in Cameroon in July/August 2000, to study musical scales of Bedzan Pygmies and of Tikar music (mission with the ethnomusicologists Nathalie Fernando & Fabrice. Marandola, under the direction of Simha Arom).
