Offsetting and Stretching

OFFSETTING AN AUDIO LAYER

You can time offset an audio layer the same way as with video layers. Click on the audio layer block and move it left/right, which will change the time offset parameter values at the same time. Shifting the block to the right will make it start a bit later, as you can see with the waveform.

INCREASING PRECISION BY MOVING A BLOCK BETWEEN FRAMES

There is also a more precise way of moving an audio layer. By default, moving this block is constrained by the composition frame rate, meaning it can only shift at the frame level. If you zoom in the Timeline, moving the cursor will go frame by frame, and this movement is also constrained at the frame level.

But, if you hold down the Ctrl / Cmd key while moving, you can shift the block between frames, which will synchronize audio elements and visual elements, aligning visual elements with audio beats. Moving the block again without the Ctrl / Cmd key will snap it to the frame.

STRETCHING AN AUDIO LAYER TO SPEED UP OR SLOW DOWN A TRACK

If you select an audio layer and unfold the Retiming group, you will see the Time Offset value. Just underneath, you’ll find a Speed Multiplier.

This parameter will stretch the sound and change the pitch of your audio source, letting you play the audio stream faster or slower.
