APL-Huddersfield/MAIR-Library-and-Renderer: MAIR library and renderer v1.1

by Applied Psychoacoustics Lab, University of Huddersfield Copyright (c) 2017 Hyunkook Lee and Connor Millns h.lee@hud.ac.uk, connor.millns@hud.ac.uk Description MAIR is an open-access library of an extensive set of room impulse responses (RIRs) captured using numerous microphone arrays from 2-channel stereo to 9-channel surround with height. The RIRs were obtained for 13 loudspeakers placed in various positions on the stage at St.Paul's concert hall in Huddersfield, UK (RT60 = 2.1s). The library features five 2-channel stereo pairs, 10 main surround arrays, nine height microphone arrays for 3D main arrays and 15 4-channel configurations for surround and 3D ambience arrays, each with varied microphone polar patterns, directions, spacings, and heights. A dummy head and a first-order-Ambisonics microphone are also included. The library is provided with a rendering tool, with which the user can easily simulate different microphone combinations in both loudspeaker and binaural playback for 13 source positions. The audio inputs for the rendering tool can be directly fed from a DAW session as well as by manual file allocation. Prerequisites Max 7 must be installed to run this software. It can be found and downloaded for free here: https://cycling74.com/downloads NOTE: A Max 7 license is not required to run the MAIR Rendering Tool. Installing Once Max 7 is installed, simply run the MAIR_RenderingTool_v1.mxf max collective file.
