Free Impulse Responses (and a paper to explain why)
Dear all
After many months of doing something else, I have finally finished to deconvolve the sweeps we did for my research project Thinking Inside the Box in a non-proprietary format (24bitWAV@48kHz) thanks to -sciss-'s amazing and free FScape software, and to the libsndfile for the pre- and post-processing.
The interesting bit is that we have measured five brands of loudspeakers (plus a sub), in five different stage positions, with five different microphone setups. It should be interesting for people who are curious about space in music, and/or for mixing purpose too. The hall is the Phipps hall, in the University of Huddersfield's new Creative Arts Building, where the next ICMC will be held!
The loudspeakers are Bellecour360, BoseL1mk2, Genelec1037, Mackies450mk1, Meyer UP-J 1P, and a Meyer M1D-sub. A good combination of commercially available studio, PA and radiating loudspeakers.
The stage positions were Left, Centre-Left, Centre, Centre-Right and Right.
The five destinations were on-axis XY (matched DPA 4011s), on-axis 5.0 (matched DPA 4006s-11s in a decca tree), on-axis binaural (Neumann KU100), off-centred AB (matched DPA 4006s) and off-centred XY (matched DPA 4021s). You can take the 5.0 L and R to make an on-axis AB if you miss it ;-)
For more information on the primary use of them, please refer to the published ICMC paper entitled 'Thinking Inside the Box: A New Integrated Approach to Mixed Music Composition and Performance' available online at the same repository.
The executive resumé is: please do mixed music in the studio through IRs of halls so you can see how you mix will port for everyone in the room who paid for a ticket, not just the 5 who are lucky enough to be in the sweet spot ;-)
That kind of work would have not been possible without AHRC and HEFCE's SRIF help, and the patience of my postdoc assistant, and the support of my institution.
the IRs are available for free to download at the same address than the paper
Comments are welcome, and feel free to share the link.
