Très intéressant !HOW DOES IT WORK?
The Tidal test had you try to identify which of two versions of a track was lossless for each of five tracks.
This test will instead test whether you can tell the difference between the lossless and lossy version, without choosing which is which. It does this using an ABX test.
You will be presented with two reference samples (A and B), and a target sample (X). You have to decide whether sample X matches sample A or sample B. You will be administered multiple trials for each of the five tracks used in the original Tidal test.
The accuracy of the test will increase markedly as the number of trials increases. Although 5 trials is sufficient to estimate whether you can tell the difference between lossy and lossless, to work out which tracks you can tell the difference on will require 20 trials per sample.
C'est chaud !
