Max for Live: Extreme Time Stretching with Spectral Stretch

Image
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 ...

Composers, publish your scores!

Image
Since I self-published my score Bleu 3 , a number of colleagues and friends asked me a " score self-publishing 101 " session. This post is intended to help anyone interested in self-publishing, especially composers. Some of these tips may be equally useful to make a book of your favorite recipes (a nice present for your friends). Actually, self-publishing is quite easy today, and you will surely find useful the article "Upload" from Make magazine, issue #12 . First of all, why self-publishing? Why don't all composers work with a publisher? Last year, I discussed this question with composer Julian Anderson , published by Faber Music . As he explained to me, publishers have two roles: first , the promotion of the music, and second , the printing side of the business (making scores and parts available). They are especially useful when they promote the music and their catalogue is well diffused. This is the case for rather big publishers, who are well connected to...

Freeze a sound with Max/MSP/Jitter

Image
In April 2008, I was invited by composers Eric Chasalow and Maxwell Dulaney to give a 2-day seminar on spectral sound processing techniques at Brandeis University Music Department . A topic the music students particularly enjoyed was the frozen sound , the audio equivalent of the cinematic " freeze frame shot ". I taught the nuts and bold of the real-time stochastic spectral freeze technique (the stochastic component is aimed at breaking the ice - with the audience). On this video , discover 5 variations on a Max/MSP/Jitter freeze tool: Downloads Note: the Max patches available here have been completely revamped since this article & video were initially published.
