The Basic Editing Options
Selecting the basic editing options menu-item from the edit audio le button menu causes a dia-
logue-box (Fig. 1.9.4) to be shown. From this dialogue-box, you can access a number of useful tools for
working with audio les. Be aware that these operations are all destructive, so be sure that you wish to
make permanent changes to your source audio le!
The operation type eld shows a drop-down menu when selected. From this menu you can select
from a number of different operations. The options available below this eld will change depending on
the operation selected.
Trim silence: Use this option to remove audio that is below a given threshold from either end of the
audio le. When this operation type is selected, the following options are available (Fig. 1.9.4):
•
Threshold: Any audio below this threshold will be trimmed.
•
Trim start: When this option is selected, audio below the threshold level at the start of the wave
le will be trimmed.
•
Trim end: When this option is selected, audio below the threshold level at the end of the wave
le will be trimmed.
Normalise: Use this option to adjust the level of the audio such that the peak level of the wave le
reaches the desired normalise level. Typically, normalisation would be used to make an audio le as
loud as possible without introducing any digital distortion, or clipping. There is only one option available
for normalise, peak level, and it is this level to which the le will be normalised (Fig. 1.9.5).
