Recordings of the BART, recorded in San Francisco's Powell Street Station, manipulated with AudioThing's Noises, then modulated repeatedly using Cableguys' Shaperbox. All the Shaperbox modulations used the barcode from a packet of Walker's Shortbread Fingers to define the gates. These, depending on the effect, are then stretched between 1/16 and 32 bars.
