Audio Freeze - From Melody to Harmony

On my August 2008 post entitled A Free Tutorial on Spectral Sound Processing Using Max/MSP and Jitter, Alex asked: "I was wondering if you also put "Melody to Harmony" patch on line".

Good news, the patch is online! It is called 6-melody-to-harmony and free to download on this page: Jean-François Charles' Max MSP Jitter patches (link updated 01/12/2010).

A multiple freeze

With this patch, you can freeze a note, then add other notes, thus creating a frozen chord. There is no limit on the number of notes that you can freeze: it doesn't take more resources to freeze 100 notes than 2. By freezing successive notes of a melody, you transform it into harmony, in real time.
This patch uses the Max MSP FFT capabilities, while spectral data is stored and computed within Jitter matrices.

Max 4 version of the patch?

Antonio commented "pity some patches are for version 5 only" ; that's right, some of the most recent patches are only compatible with Max 5 and later. For this "melody to harmony" patch, you can click and enlarge the picture below. You will see the whole patch and the [pfft~] sub-patch. You can make a new Max 4 patch by patching the objects you see in the image. All are standard objects are available in Max/MSP 4.6 and Jitter. Nothing is hidden. The black rectangles are [jit.pwindow] objects.

This is the Max 5 version. You can build a Max 4 patch from this picture.

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

GroundSwell 2020 Emerging Composers Competition

Image
Groundswell is a wonderful organization dedicated to the development of new music in Winnipeg and the Province of Manitoba, Canada. I've been invited to serve as a member of the committee for their first electroacoustic music competition, along with composer Margaret Schedel and composer William Brunson . It's been a fun and quite interesting adventure. We listened to more than two dozen compositions. I wish we could have included more than 5 finalists: there were a number of atypical nice compositions. To listen, head to the competition page . You'll find links to the finalists' music.

A Free Tutorial on Spectral Sound Processing Using Max/MSP and Jitter

Image
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
