It has been proposed to me that no AB/X study can be valid without a hypothesis, that further, to be valid the hypothesis must be tested against a null hypothesis and that this...
This study aims at investigating whether listeners can perceive differences between musical files recorded at 44.1kHz and 88.2kHz with the same analog chain and type of AD-converter.
