DIY hydrophones: Violet and substrate sonics.

Several hydrophone recordings made in the Goolwa (East Fleurieu) area using a the DIY built hydrophone ‘Violet’. These recordings have been mixed together to create a work-in-progress composite sound image. A majority of the recordings here are the result of the hydrophone being buried in sand near the water to capture the sonic environment of the substrate. Notable elements include: wind ‘playing’ the exposed XLR cable, the dynamic peaks of sand and other small particles moving past or making contact with the hydrophone, and the ‘groan’ of large densities of sand shifting in close proximity to the hydrophone. Basic fades, spatilisation, EQ and filtering have been employed to render a consistent sound image and accentuate the respective qualities of these sounds.
