Visualising the Audio Spectrum in 3D - Max/MSP Tutorial

You can create really beautiful and interesting things by the frequency domain analysis of audio. This is a (hopefully) accessible and practical introduction to the world of FFT - in this video, I use [pfft~] to capture the frequency domain data into a Jitter Matrix, and visualise it both as a scrolling display and a 3D image using [jit.gl.mesh] and [jit.gen].
