How to properly compare audio samples and why is that important?
1. Compare the audio samples on a computer device that has no significant pre-defined sound settings.
(We have contacted a couple of vendors to ask if there is a way to turn those pre-defined sound settings off, either in BIOS or somewhere else. Their answer was "no" without further clarification.)
(For example, a test was done using the same speakers on a home PC with a dedicated sound card and on a laptop* with an integrated one. As the laptop’s integrated sound card had pre-defined sound settings, the sound comparison did not make sense, as it was not realistic.)
