4 Select the Pencil tool, and drag from left to right (including up or down movements) to
draw in a new shape to the waveform spike. The edges of drawn sections are
automatically smoothed. Press Option to affect both sides of stereo waveforms.
As long as the mouse button is held down, the drawn waveform can be replaced by

Changing the Level of an Audio File
You can use the Change Gain command to change the level of an audio file. You would
typically use it on an entire audio file, but can certainly boost portions of it.
To raise or lower the level of the selected audio file (or area) by a specific amount:
1 Choose Functions > Change Gain.
2 Choose the desired settings in the Change Gain dialog:
 Set the required level change by clicking on the up or down arrows, or by directly
typing in either Change Relative field. You have a choice of a percentage or decibel
increase or decrease.
 Click on the Search Maximum button to search for the highest peak level. This
automatically sets a value that is used to alter the level of the audio file. The Results
in Absolute fields displays the maximum level that will be achieved by changing the
gain (by the amount shown in the Change Relative fields).
3 Click Change (or press Return) to perform the gain change.
