How the audio score is calculated

Audio hardware: stereo speakers (60%, required), 3.5 mm headphone jack (40%).

Does not measure loudness or sound quality.

Inputs, weights and scales for the audio score (formula version 2.6). Values between two points are scored on the straight line between them; values beyond the ends get the end score.
Input	Weight	Required	Scale: value → points
Stereo speakers	60%	yes	yes = 100, no = 0
3.5 mm headphone jack	40%	no	yes = 100, no = 0

Worked example

The Motorola Moto G77 Power is #3 in the current audio list. Its audio score of 100 comes from these inputs:

Motorola Moto G77 Power: audio score step by step. Points are on the 0 to 100 scales above.
Input	This phone	Points	Weight	Contribution
Stereo speakers	stereo speakers	100	60%	60.0
3.5 mm headphone jack	3.5 mm headphone jack	100	40%	40.0

The contributions add up to the score. An input that is not confirmed is left out and the remaining weights are scaled up to 100%, except where the category counts an unknown input at the middle of its scale (shown as "counts as 50").
