impulse responses

Here you'll find impulse response (ir) recordings taken from various places. You can feed them into convolution reverb plugins like e.g. SIR (v1 is freeware, v2 not) or Voxengo pristine space (payware) to recreate the room they were taken in. All ir files have been captured using the single shot method for reasons of simplicity. Every response file is 24 bit / 96 kHz stereo, uncompressed pcm. Remember that such a response can only be like a snapshot, a polaroid of the conditions at the time it was taken. At the bottom of the page you'll find an archive with all impulses conveniently packed together. If you have any question, suggestion, or problem, you may very likely find a corresponding thread in our message board.

tunnel ir location 4: tunnel
A car tunnel with a length of 1080 m; inner dimensions being 9,5 x 4,5 m. The second recording is the same impulse travelling through the whole tunnel. You can either cut away the 'silence' (tunnel ambience) at the beginning or leave it as is for the delay the sound will have just by passing through the whole 1080 meters.
