HISSandaROAR SD059 POLYSTYRENE Sound Library is now released!
For early bird 33% discount use coupon code “CHIRP” (expires May 21st)

This library is a sequel to SD040 PLASTIC POLYMER except this time we’re exploring EPS – Expanded Polystyrene – a rigid synthetic material that is over 90% air (also known by the brand name Styrofoam)

Once you get past the annoying squeaks, polystyrene is capable of generating and amplifying a vast range of sounds, and I was reminded of what a sonically useful material it is when working on development of a new physical musical/sound FX instrument (more on that soon!)

The combination of rigidity and incredibly low mass makes EPS a useful resonator but is also capable of generating quite strange sounds itself including creaks, squeaks & shrieks, breaks, tears, clicky ratchets, weird vocalizations (dolphins on acid?) and pitchy tumbling impacts.

These sounds were recorded 32bit 192kHz using a pair of Sanken CUX100K microphones for extended 100kHz range and an MKH8020 was placed inside objects when possible, useful for its pronounced bass response.
