Impulse Responses

For Sound Design Media, a course on my Masters, I had to produce 20 impulse response files. As well as taking a number of more traditional IR’s (taking advantage of my day job working at the Scottish Parliament as a tour guide and mapping many of the halls and corridors of power) I also decided to experiment with more unusual objects, attempting to create interesting effects rather than typical reverbs. This recording is a demonstration of the 20 IRs I collected, each applied to the same sample, with the first being the dry sample for reference.

Here is a list of the impulse responses I collected, in the order they are played above (stereo unless stated):
