Huddersfield Universal Listening Test Interface Generator (HULTI-GEN) Version 2

This paper describes a new version of HULTI-GEN (Huddersfield universal listening test interface generator). The Max-based tool features a number of new improvements over the previous version, including the addition of psychometric testing methods (e.g., 2I-2AFC, ABX, Yes-No, etc. in adaptive and non-adaptive procedures) to the existing ITU methods; playback of multi-channel stimuli (up to 64 channels); a SOFA-based, real-time binauraliser with headphone equalisation filters; statistical-analysis-ready results files; and an open-source framework for experimenters to modify the existing tests or design their own test methods for HULTI-GEN. The tool is designed so that the setup, testing, and results gathering processes are effortless. The software is freely available from
