A sonogram (also called spectrogram) represents graphically the distribution of energy of a sound through frequencies, in function of time.It may be funny or useful to transform the data graphically before resynthesizing the sound. This is made easy by a development environment like Max/MSP/Jitter, which allows to work in real time with sound and video.In this video, I show a few graphical treatments one can apply to a sonogram:If you wish to realize similar sound processing, here are Max/MSP/Jitter patches for spectral sound processing.Update: Computer Music Journal Tutorial on Graphical Spectral Sound SynthesisRead more explanations about this type of graphical sound synthesis in the free pdf article: A Tutorial on Spectral Sound Processing with Max/MSP & Jitter.

In 2001, I composed the Arc-en-ciel Formula. It is both a musical work for Bb clarinet and double bass, and a "musical formula" on which I have based the Arc-en-ciel cycle. Here is the score:Page 1: red, orange, yellowPage 2: green, blue, indigo, purpleA cycle in seven partsThe Arc-en-ciel cycle is based upon the above formula. At the time, I was very interested in the music of Karlheinz Stockhausen and in his technique of Formula Composition, as well as in Fractals (Formula Composition is an application of fractal thinking to musical composition).RedMagma for contrabass clarinet, stones, and live electronics (2003)OrangeWu jú sè for clarinet, percussion (5 chinese gongs), double bass, and dance (2002)YellowZygomatic for voice and live electronics (2005)Risorius for six voices (2005-2006)GreenRêver for singing dancer and dancing clarinetist (2004)BlueAqua for solo double bass, aquaphon, clarinet, and live electronics (2004)Aqua Solo for solo double bass (2004 / 2008)IndigoPa…

I am just back from Montbéliard, France, where I took part in the July 2008 Prisma Meeting.Prisma is an international group of composers and researchers founded in 2001 at the initiative of Jacopo Baboni Schilingi. Prisma stands for "International Pedagogy and Research on Assisted Musical Systems." I joined in 2003 at the invitation of Jacopo Baboni and Hans Tutschku. The group meet regularly to exchange and build musical knowledge.This time, the schedule looked like this (original untranslated program):Saturday 07/05Générations musicales temps-réels de populations d'agents neuromimétiques (Frédéric Voisin)Rules for controlling Energy Profiles (Orjan Sandred)First steps towards Klangpilot3, a realtime system for learning sound synthesis (Johannes Kretz)Six hermeneutical models (Jacopo Baboni Schilingi)Sunday 07/06PWGL - News (Mikael Laurson, Mika Kuuskankare, and Kilian Sprotte)More PWGL News (Jacopo Baboni Schilingi and Orjan Sandred)Practical workshop on PWGLMonday 07/…
