Field notes
The page describes a live meter with period averages, peaks, and a count of roars, then a post-match report that includes time spent in each zone and a chart of the match. Users can switch off roar clips in Settings, and the stated calibration range is up to ±20 dB. Three group games are also detailed: chant duels, goal screams, and holding a room silent.
