Drone Archeology

This CD, produced by Numerical Sound, contains 99 stereo drones, ranging from 32 to 64 seconds in length. The drones are all steady in pitch, but have constant movement, thus they are never the same from one moment to the next. In order to aid multimedia and film production, the drones have been classified into seven categories as follows: Nature, Science, Drama, Industry, Voice, Bell and Drones.
