Go to the Audacity download page and click the operating system you are using to download the latest version of the software. Note: The latest Beta release is best for the latest versions of most operating systems including Windows 7, Windows Vista, and Mac OS X 10. 6. Double-click the Audacity installer file you’ve downloaded and follow the on-screen instructions to install the software.
Click the scissors icon from the toolbar to “Cut” or delete the region of audio you’ve selected. This method can be used for deleting portions of a song, shortening the length of the audio, and more.
Click the “Trim” button to keep only the selected region and cut the rest of the audio. Click the “Silence” button to silence the selected region of audio without deleting it from the timeline.
