All samples are synchronized and normalized to -18 LUFS without clipping.
In each step of the test, you will be presented with three audio clips: one is a recording of "System 1", another is a recording of "System 2" ("A" and "B") and a third one ("X") identical to one of the previous two.
For each comparison, you will need to listen and say which of "A" and "B" you think is identical to "X". The goal is to see if you can reliably tell the difference between "System 1" and "System 2".
The "A" and "B" labels are randomized and do not always correspond to the "System 1" or "System 2". The order of the listening samples is also randomized.
