UnverifiedAudio waveform alignment is a post-production synchronization technique: during shooting, create an obvious sound pulse (such as a hand clap) at the start of each clip; this pulse forms a sharp peak on the audio track, and by aligning the peaks to the same point in time, the starting actions of multiple clips can be made completely synchronized, which is more precise than purely visual alignment.79% similarUnverifiedIn a ceiling-fan outfit change, if you forget to clap, you can also use the periodic noise generated by the fan's rotation as an audio alignment reference, but the precision will decrease.65% similar
