Polarity offers over 950 sounds of electricity, science, and technology – captured in multiple locations around the world, from electricity museums to science laboratories. About 50% of the library is about electricity, with various types of Jacob’s ladders, Tesla coils, Rumkoff lamps and various impactful bursts of energy.
Then we started covering a wider range of technical topics – such as old telephones, telegraph machines, generator wheels, rotating dials, rotating observers, alarms, laboratory centrifuges – through welders, plasma balls, 3D printers , what scientists call rollers and rockers, servo sounds, neon lights, Wilmshurst machines and fireworks.
Many of the sounds in this section were captured from vintage equipment, from a 1928 tram to old telephone switches, high voltage poles and control surfaces.
All content was recorded at 192KHz using a Sanken CO100K, several Sennheiser 8040s and a Neumann 81i, translating into a final asset with extensive ultrasonic content, ready for the most extreme operations.
