Adjusting wavefile

Hello all,
I’m new to Audacity but have used N-track for years. I can’t seem to find the way to adjust the length of a track. I have a song where I only want apporximately the first 1:33 seconds. I need to take a 3 minute file and reduce to this length. Can someone help me with this please?
Thank you

In what way do you want to do that? Do you want to:

  • Delete some from the start or end
  • Chop out part from the middle
  • Speed it up (like playing a tape or record faster)
  • Increase the tempo without changing the pitch
  • Something else

Sorry that I wasn’t clear.
I would like to do option #1 (Delete some from the start or end)

Thank you!

Deleting is easy.

  1. Select the part that you want to delete.
  2. Press the delete key (or select “Delete” from the Edit menu)

There are several ways to “select” audio. Often the quickest is to just “left click” with the mouse on the waveform and drag while holding down the left mouse button. Other ways are described in the manual here:

To make a very precise selection, you may want to zoom in on the waveform:

Note that when you have finished editing, to create a normal audio file you must “Export” in whatever format you require.

There is a “Getting Started” guide in the manual - available on-line here: or if you used the recommended Windows installer, just go to “Help menu > Quick Help”.

Thank you, Steve!!!
You’re a great help!!!
