"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.

MAIR-Library-and-Renderer

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.

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. ‌
