ABX audio test

Blind comparison

Can you identify the difference?

Choose two audio files. WaveLocus decodes them only in this browser, starts each preview at sample zero, and makes only A, B, or randomized X audible. The files are not otherwise time-aligned, and they are never uploaded.

RMS matching measures average digital sample energy and only attenuates the louder file. It is not LUFS, perceptual loudness matching, or a claim that the files are otherwise equivalent.
