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 synthesizer

Oh, and since I posted this (and accidentally left out the video), here’s an additional one in the series with Max for Live.
