AES Convention 138 · Paper 190 · May 2015

Abstract

This engineering brief describes a new, open source code library named HAART (Huddersfield Acoustical Analysis Research Toolbox). HAART simplifies the measurement and analysis of multi-channel impulse responses (IRs). For the purposes of this engineering brief the code library is compiled as a set of Max objects that form a prototype program in Max. This program is able to perform the acquisition, manipulation and analysis of IRs using subjective and objective measures described in acoustics literature. HAART is also able to convolve IRs with audio material and, most importantly, able to binaurally synthesize virtual, multichannel speaker arrays over headphones, negating the need for multichannel setups when out in the field. The code library is freely available from: http://www.hud.ac.uk/research/researchcentres/mtprg/projects/apl/
