MAIR is an open-access library of an extensive set of room impulse responses (RIRs) captured using a total of 40+ microphone techniques from 2ch stereo to 9ch 3D as well as those for 360deg audio capture. The library is provided with a rendering tool that enables the user to create virtual recordings for both loudspeaker and binaural playback.

HULTI-GENv2

An update to the original HULTI-GEN listening test software. Now includes psychometric testing, real-time binauralisation, and features a modular setup to help expand its testing capabilities in the future.

HAART

"All in one" toolbox for impulse response acquisition, manipulation, analysis and auralisation. HAART aims to provide audio and acoustics researchers with a quick, easy to use, all-in-one box solution for acquiring, analysing and auralising multichannel room impulse responses. Acquisition via multi-in / multi-out setups using exponential sine sweep or maximum length sequence method. Analysis of ISO3382 and other concert hall acoustics parameters. Convolution with multi-channel RIRs for multichannel speaker setups and binaural auralisation over headphones.

HULTI-GEN

HULTI-GEN takes user-defined parameters (e.g. the type of scale, the number of trials and stimuli, randomisation, settings for reference and anchors, etc.) and automatically constructs a GUI suitable for the requirement of the listening test. This allows the user to quickly create various types of multiple and pair-wise comparison test environments. To assist the user, HULTI-GEN also provides a number of presets based on ITU-R recommended methods such as MUSHRA and ABC/HR. The user can also flexibly edit these presets to adjust the recommended methods for different test requirements (e.g., adding audible anchors, removing hidden reference, etc.). Subject's responses are saved as a text file, which can be easily imported into Excel for data analysis. HULTI-GEN supports the playback of multichannel wav. file of up to 28 channels, which is useful for multichannel 3D sound quality evaluations. ‌
