24-bit/48kHz Royalty-free Sound Design Collection
Unseen Noises is the second sound effects bundle created by sound designers and electronic composers Matteo Milani and Federico Placidi (aka Unidentified Sound Object - U.S.O. Project).
Electromagnetic informations are invisible and omnipresent. In every city, especially the big ones, an infinite number of electromagnetic waves is hidden: we can't hear them, but they're everywhere! We explored this invisible noise pollution transducing electromagnetic fields into audio signals with a telephone pickup: it acts like a radio antenna for hum and weird electromagnetic noises.
We plugged it into a SONOSAX SX-R4 recorder, moving it close to electrical devices - like a stethoscope - to locate interesting and curious sounds, just like LCD television, internet antennas, lighting systems, transformers, game consoles, tablet, electronic security systems, scanners, computer monitors and hard-drives, printers, navigation systems, fax machines...
All of the audio files have been embedded with metadata for detailed and accurate searches in your asset management software.
As the previous library, this collection has not been peak normalized, but loudness normalized. Through loudness normalization, the gain of a signal is modified so that the signal’s loudness level equals -23 LUFS. Loudness normalization helps us solve the problem where we wish to balance the loudness level of multiple sound files.
