Import the song file, if it's not already on your computer, by connecting the recording device to the computer via the mic jack. Press play on the recorder while pushing record within your editing software.
Name the file that will serve as your song file. To do this, go to "File," press "Save" and type in the desired name of the file.
Notice the wave file of the song within the viewing pane of your software. This is a visual representation of the audio waves of your song. Familiarize yourself with the wave file and pinpoint the desired portions you wish to edit.
Highlight that portion of the wave file with your cursor and press delete to delete a segment of a song.
Cut a portion of a song and insert it elsewhere by highlighting the portion of the song you wish to cut. Click "Edit" and then "Cut." Move your cursor to the desired location where you'd like to insert the portion and click "Paste."
Adjust audio volume levels of different portions of your song by highlighting a portion of the song and using the adjust audio tool. If you don't have such a tool in your program, consult the user manual to find a similar tool. This will typically allow you to adjust the audio levels in one of two ways: visually, allowing you to drag your mouse up and down to raise the volume of certain segments, or by manually entering in different decibel levels.
Click save to retain the changes once you've made all the edits to your song.
