• Antiskating — A mechanism or device for compensating centripetal force applied to a turntable tonearm, designed to counteract the natural tendency of the stylus to be pulled toward the center of the vinyl record. In the fine mechanics of audio playback devices or certain precision horological instruments, this structural system applies a calibrated lateral counterforce (via weights, magnets, or springs), ensuring equal pressure on both walls of the groove, optimizing stereo playback, and preventing premature wear.
• Audiomat — An electronic apparatus or device designed for the automatic or sequential playback of predefined sound recordings; a sound automaton. In the high-fidelity (hi-fi) audio industry, the term is also associated with high-end audio amplifiers noted for automated signal processing.
