New sounding machines, rumbles, room tones and start-ups recorded from classified and restricted experiments. Every little servo and small gear-head motor sound was recorded to get a multitude of different sounds at work. Top sound designers were then consulted and happily agreed to contribute space and science effects, and various medical research machine sounds recorded both externally and internally. To close the investigation, the Edge team uncovered a special bonus disc from Scott Sanders. A telemetry disc of interesting radio short wave sounds and statics derived from microwave, VHF, UHF and low-band that all contribute to the radio spectrum. After all data had been investigated, reviewed and recorded, The Edge team released the Hi Tech and Top Secret Sounds set available for you.
