HISS and a ROAR has announced the release of its second impulse response sample library. Following on Glass Object collection, the new Metal Object IR library explores the acoustics of 43 metal objects.

The collection contains a total of 275 impulse responses, captured with three specific approaches:

  • Empty metal object IRs ranging in size and scale from a tiny soda can to a huge grain silo, sweeps were captured using MKH80X0 mics, in stereo where possible with the large objects, while the very small objects were captured using a DPA4060 mic.
  • Pitch shifted IRs at half speed & quarter speed. Processed versions of each IR are included, pitch shifting and slowing the IR to half speed and quarter speed to expand its use with a wider range of source material.
  • Iterated IRs, playing the captured IR back into the same object.

The IR library costs $19 USD.

Also released is the new Unit FX series library featuring recordings of a Model H-16 Bolex film camera, which is powered by a hand crank that you wind up.


There are few gentle mechanical sounds as evocative as the smooth whirr of a wind up Bolex 16mm film camera. I can only presume it is due to the Swiss history of watch making that the country is home to two of the most beautiful technologies associated with film making: Bolex cameras and Nagra reel to reel sound recorders. Apparently as far back as 1790, the city of Geneva alone was exporting 60,000 watches per year – thats 200+ years ago now!

Available for $15 USD, the UFX009 BOLEX H16 Film Camera library includes 60 stereo .WAV files (24bit/192kHz) with metadata and photos.

HISS and a ROAR newsletter subscribers can get a 33% early bird discount on both sample libraries until May 16th, 2021.
