Please feel free to download and use these impulse responses. These IRs require Audio Ease’s Altiverb 7.

I’ll add new impulse responses over time. Sign up to the free newsletter to learn when new IRs become available.

Interior Impulse Responses

High-Rise Stairwell

Impulse responses from a 1970’s-era 23-floor high-rise.

Version 1: 11th floor

High-Rise Stairwell - 11th Floor - 1 meter

The location is midway up the height of the building. The reverb echoes extensively up and down the vastness of the stairwell.

High-Rise Stairwell - 11th Floor - 3 meters

A second IR was recorded there, at three meters. It is similar to the IR above, but broader due to an increased distance, at half a floor above.



Version 2: 23rd floor.

High-Rise Stairwell - 23rd Floor - 3 meters

An IR from the top floor of the high-rise. Similar to the other high-rise recordings, but adds a more metallic cast due to the structures in the area. The ceiling is also higher, which adds a broader aspect to the reverb.



Small Sauna

Small Sauna - 1 meter

A small 1.5 meter by 4 meter wooden sauna. A tight, intimate location.
