All of our environmental impulse responses are generated through a wave field synthesis speaker on location and recorded in both stereo and omnidirectional mono to give you realistic representations of that location. Where relevant, we supply IRs of a given environment recorded from two diametric positions, e.g. at a waterfall or at the beach where you would get a different sound if the water was in front of you or behind you while recording.
Packaged with our environmental IRs we also provide a ten-minute recording of the actual location so that you have the option of layering in a track of the true sound of the place in addition to capturing your instrument’s timbre in that environment. You might get some unwanted sounds in there, but with ten minutes of audio you can certainly edit out any people sounds or bird calls that you don’t want.
