What this audio test checks
The buttons cover the four things that most often go wrong: channel routing (left/right swapped or one side silent), frequency range (missing bass or treble), cleanliness (buzz, rattle, crackle) and wiring (polarity). A failure tells you which detailed tool to open next.

Audio test vs sound test vs speaker test
They overlap. This audio test is the quick check; the sound test adds more frequencies and noise colours; the speaker test adds sweeps and phase for speaker setups; the headphone test focuses on earcups, imaging and treble.
