Shows a + representing source position one, and a series of x’s marking the receiver positions for that source. These therefore correspond to these IR files: newgrange_s1r1.wav newgrange_s1r1_2.wav newgrange_s1r2.wav newgrange_s1r3.wav newgrange_s1r4.wav newgrange_s1r5.wav newgrange_s1r5_2.wav newgrange_s1r6.wav The _2 suffix indicates a second IR recorded with that same source/receiver combination.

Shows three +’s, marking source positions 2, 3, and 4. For each of these source positions the receiver was at the x mark. The IR files this corresponds to are therefore: newgrange_s2r1.wav newgrange_s3r1.wav newgrange_s4r1.wav

Shows one + and one x. For one recording the + was the source position (i.e. source position 4 as above) and the x was the receiver position (i.e. receiver position 2 for source position 4). The receiver and source were then swapped with one another to give source position 5 with the source at x and a receiver at the +. This then corresponds to the two IR recordings: newgrange_s4r2.wav newgrange_s5r1.wav
Waveform Example
IR recording for source position 1 with its receiver in the first position – here the source is just about central in the main chamber, and the receiver is at 1.1m distance towards the mouth of the chamber. See images for details.

Rotated IRs
After these measurements were made, it was discovered that the microphone used had been assembled incorrectly. This has resulted in a Z-axis rotation of 120 degrees in the original IRs. This link provides access to rotated versions of the IRs, along with the MATLAB scripts used to perform this fix.
