Editing audio in the Timeline panel
Set sample-based audio In and Out points
In and Out points are set at timebase divisions—that is, between video frames. Although frame-based edits are
usually adequate for audio as well, some audio edits require greater precision. For example, you may want to place
an In point between two words in a sentence, but the tiny division between words doesn’t conveniently fall between
frames. Fortunately, digital audio isn’t divided into frames, but into audio samples, which occur far more frequently.
By switching the Source Monitor’s or sequence’s time ruler to audio samples, you can set more precise audio In and
Out points.
