‘Submerged’ SFX Reeled In For Radio


Does your station seek a little gurgle or water-logged warble in its communication to listeners?

A Brooklyn-based sound effects library company has released an audio catalog of 230 sound effects recorded using an underwater microphone.

Pro Sound Effects’ latest library, Submerged, used a hydrophone to put together the collection of underwater sounds. This gives sound professionals the power of the sea to enhance the unique sonic properties of water in their audio project.

Among the varied sounds available are underwater fireworks explosions, cyclones, air releases, and cracking ice; and fundamental water sounds including bubbling, bu
bble streams, splashing, rushing/dripping water and an assortment of underwater vocalizations needed for any underwater scene.

Created in collaboration with Colin Hart and Joseph DiMarco of Big Tree Media, the library is designed to provide possibilities for otherworldly sound design with distinct underwater actions and immersive perspectives.

 “Hydrophones opened up a whole new world of sonic experiences to us,” says Colin Hart, recordist of Submerged. “This library offers a deep dive into our discoveries packaged as instantly usable sound effects.” As an additional resource to supplement Submerged, Hart has also published an informative guide to hydrophone recording strategies on the PSE Blog entitled “Tips for Recording Underwater Sound Effects with a Hydrophone.”
