Guinea Pig 2

This is a software-based subjective test system developed for HUT Acoustic Lab and Nokia, running on an SGI IRIX platform.

Some neat features:

Can perform not only the familiar A/B/X and A/B scale hidden reference (ABC/hr functionality), but also A/B, Ref/A/B, A/B scale, A/B scale fixed reference, single stimulus, two alternatives forced-choice, and rank order.

Can play multiple simultaneous streams and cross-fade them for switching, which eliminates switching delay and minimizes audible glitching when switching.

I wonder what other proprietary listening test software exists that labs are using?

I only know of MUSHRA and the software David Ranada used for his Sound & Vision codec tests.
