- Tap tempo averages the latest four taps; release references map calculated times to nearest discrete settings on named hardware compressors.
Field notes
The tap-tempo tool updates its estimate as each new tap is entered after the initial four. Its hardware release reference covers named models including the 1176, CL 1B, Distressor, Fairchild, Shadow Hills, and TG1, matching calculated times to the nearest available setting. For reverb, the page explains that each size combines pre-delay and decay; it explicitly leaves the final choice to the source, arrangement, algorithm, and desired sound.
