Since then, he has created an enormous amount of work - most of which is based on one sound source. Anything is used - from glass to oscillators and even pages from the Bible.
As stated previously, each recording in Aube's catalogue is synthesized from one source sound. Many of his earliest recordings use water as a source, in either a still form or a gush, as from a faucet or a stream

Any else ever listen to him? I've heard Cardiac Strain, the source being a heartbeat. It's really good music made all the better knowing it's only from one source.
If you haven't heard him before, you should check some of his stuff out.
