This detects transients across the audio file, overwriting (after you confirm the action)<br />

any manually added or edited transients.<br />

Note: You can also detect transients in factory audio <strong>Apple</strong> Loops. This saves a copy of<br />

the audio <strong>Apple</strong> Loop to the project’s Audio Files folder.<br />

Using the Pencil Tool to Edit in the Sample Editor<br />

You can use the Pencil tool to correct clicks and pops in your audio, by drawing in the<br />

waveform display.<br />

You may find it useful to change the viewing mode of the waveform so that it shows the<br />

data structure. For details, see Customizing Waveform Display in the Sample Editor.<br />

To correct pops and clicks with the Pencil<br />

1 Navigate to the desired section of the waveform.<br />

Tip: Pops and clicks are often the loudest part of an audio file, so you may find the<br />

Functions > Search Peak command useful when looking for them.<br />

2 Use the zoom controls to magnify the section of the waveform that you want to correct.<br />

3 Use the Pointer tool to scrub the audio around the pop or click.<br />

This will help you to identify exactly where you need to draw.<br />

4 Select the Pencil tool and drag from left to right (including up or down movements) to<br />

draw in a new shape for the waveform spike.<br />

The edges of drawn sections are automatically smoothed.<br />

Press Option to affect both sides of stereo waveforms.<br />
