VU meters | +VU meters are the dinosaurs (1939) amongst the meters. They react very slowly, averaging out peaks. Their specification is very strict (300ms rise-time, 1–1.5% overshoot, flat frequency response). Ardour's VU meter adheres to that spec, but for visual consistency it is displayed as a bar-graph rather than needle-style (more below). - - + |
