IMPULSE RESPONSE: how to turn any room into a reverb (Gumroad)

I found this building - kind of an immersive art installation or something - near Den Osse, NL (51.7387296, 3.9014423) and decided to sample it and use it as a reverb. So I went in there, recorded a few claps with my Zoom H1n recorder and created a lofi impulse response.
