AutoTrim

Menu Command: Edit | AutoTrim

Removes leading and trailing silences from the ends of the . Unlike the command, this command works only on the selection and does not remove silences outside the selection.

Silence to keep controls how much silence to leave on the ends. Extra silence is not added if the existing silence is less than this amount. Use zero to remove all silence. The Threshold specifies the minimum, sustained level of audio that should not be considered silence. If the audio has a lot of background noise or hiss, use values above -30dB. If the audio is clean, use values below -40dB.

Leading silence, trailing silence, or both will be removed depending on the Trim option you select.

Note that if only the left or right channel is selected in a stereo sound, then only that channel is trimmed. Since it is not possible for one channel to be longer than the other, the ends of the trimmed channel are padded with silence.

To trim silences from the ends of the entire file:

  1. Select the entire file by using the Edit | Select All command.
  2. Choose AutoTrim from the Edit menu.
  3. Enter the length of silence to keep and the threshold for the silence.
  4. Choose OK.
