When I discovered electronic music during the Centre Acanthes 2000/Ircam , my favorite topic was real time sound processing in frequency domain. Hans Tutschku taught the wonders of AudioSculpt in Avignon, before Benjamin Thigpen taught Max/MSP in Helsinki. Now, the Computer Music Journal just published an article I wrote about spectral sound processing in real time and performance time ( whereas real-time treatments are applied on a live sound stream, performance-time treatments are transformations of sound files that are generated during a performance ). If you are interested in graphical sound synthesis, phase vocoder , and sonograms (or spectrograms) , I hope you will enjoy this tutorial. The great news is that you can download the article for free on the page of the Computer Music Journal, Issue 32, Volume 3 . Max/MSP/Jitter patches You can readily apply the described techniques in the development environment Max/MSP/Jitter . For a hands-on approach, make sure you download t...
Over the years, I've been blessed to make music with incredible artists. Today, I am thrilled to annouce the release of the Tenebrae album , created in collaboration with eleven unique musicians and poets. Tenebrae by Jean-François Charles The album is a 21st century reverberation of Carlo Gesualdo's Tenebrae responsories . Like the ship on the album’s cover, the music is suspended between the physical and the spiritual world. Two poetic bonus tracks, La bête and The sea , invite to meditate further on the place of life on planet Earth. First nocturne On the Mount of Olives , with Ramin Roshandel, setar Ramin Roshandel and I created the Jamshid Jam duet in December 2019. We released Jamshid Jam as an album and performed it across the United States. Together, we have also played soccer, enjoyed Persian food, and listened to a lot of music while traveling. Sorrowful is my soul , with Nicolas Sidoroff, trumpet & objects As students, ">Nicolas Sidoroff an...
In this post, I'm giving insights into the creation of the Spectral Stretch Max for Live Device . There are many ways to achieve audio time stretching without transposition . Some time-based methods build on Pierre Schaefer 's Phonogène . Another approach consists in processing the sound in spectral domain, using a phase vocoder . In this case, the audio samples are converted to spectral data through a Fast Fourier Transform (FFT). Then, even if we focus on extreme time stretching, the details of the phase vocoder implementation have important consequences on the sound quality and the tool's flexibility for live usage. Before introducing the Max for Live device Spectral Stretch, let's have a look at a selection of four possible algorithms: Paulstretch Max Live Phase Vocoder Interpolation between recorded spectra Stochastic Re-synthesis from a recorded sonogram Paulstretch Paul's Extreme Sound Stretch , also known as Paulstretch , is an algorithm designed ...
