Learn about sampling rate, aliasing, and the Nyquist frequency – stuff you need to know when working with digital audio – right in Ableton Live, visually.
Jerobeam Fenderson has posted a video demonstrating how to do that, all using a free Max for Live patch (so compatible with Ableton Live Suite, though even the demo version will let you load this and give it a go).
Looks like a must-have teaching tool for anyone working with Ableton Live.
Description and more resources:
– draws a sine wave and shows the points that would be sampled at a certain sampling rate (doesn’t actually change the sampling rate)
– phase shift to show that the sampled signal can differ, depending on it’s timing
– aliasing artifacts: shows a possible different interpretation of the same sample points
– just a demonstration tool, not really meant to be a synthesizerpatch: http://www.maxforlive.com/library/device/4228/nyquist-shannon

Oh, and since I posted this (and accidentally left out the video), here’s an additional one in the series with Max for Live.
So interesting how the sample points can create such loose representations of the wave itself. Our perception of the resulting sound reminds me of the checker shadow illusion
