ITunes was not designed to be used as an audio editor, so it doesn't have the advanced functions of an editor. However, you can use a trick in iTunes to trim your songs. If you want to remove the silence at the end of a track, or the beginning of a live concert to get rid of the applause, you can do so by using the Start Time and Stop Time options. You have to convert the song to MP3 or AAC format to trim it.

Step 1

Open iTunes and locate the song you want to trim. Double-click the song to play it and decide where you want to trim it.

Step 2

Right-click the song and choose "Get Info" from the context menu. Click the "Options" tab.

Step 3

Enable the "Start Time" and "Stop Time" and enter the time for the start and stop points into the two fields.

Step 4

Click "OK" to save and apply the changes. Double-click the song to test the changes.

Step 5

Right-click the song and choose "Create MP3 version" or "Create AAC version" from the context menu to convert the track. ITunes trims the song when you convert it.
