Digital television audio Latency (audio)

many modern digital television receivers, such standalone tv sets , set-top boxes use sophisticated audio processing, can create delay between time when audio signal received , time when heard on speakers. since many of these tvs cause delays in processing video signal can result in 2 signals being sufficiently synchronized unnoticeable viewer. however, if difference between audio , video delay significant, effect can disconcerting. tvs have lip sync setting allows audio lag adjusted synchronize video, , others may have advanced settings of audio processing steps can turned off.

audio lag significant detriment in rhythm games, precise timing required succeed. of these games have lag calibration setting upon game adjust timing windows number of milliseconds compensate. in these cases, notes of song sent speakers before game receives required input player in order maintain illusion of rhythm. games rely upon freestyling , such rock band drums or dj hero, can still suffer tremendously, game cannot predict player hit in these cases, , excessive lag still create noticeable delay between hitting notes , hearing them play.
