Figure 470. VocalSync.
The basic principle behind VocalSync is that you first specify a guide track that contains the correct timing, then you specify the dub audio that you want to align with the guide track. VocalSync then applies varying amounts of time stretching or compression to adjust the timing of the dub audio to match the timing of the guide track. You have full control over the alignment strength. Only the dub audio is modified, and the pitch of aligned audio is unchanged. The guide track is an entire track, while the dub audio can be any audio selection (a clip, a time selection, an entire track, etc.).
VocalSync uses a particular formula, or algorithm, to stretch the audio. It uses a processor-friendly algorithm for online previewing, and a more processor-intensive algorithm for offline render.
