Exactly. And „precisely“ means leveling to about 0.1 dB, difference, and this means using measurement devices and not just the ears and the volume knob.
And exactly means exactly. From @Marian ’s wonderful link, my emphasis:
The human ear can consciously discriminate amplitude differences of about 1dB, and experiments show subconscious awareness of amplitude differences under .2dB. Humans almost universally consider louder audio to sound better, and .2dB is enough to establish this preference. Any comparison that fails to carefully amplitude-match the choices will see the louder choice preferred, even if the amplitude difference is too small t…
