Open the music-creation software and import the MP3 song you're going to be editing by selecting "File" from the top menu, then "Import".
Select the "File" menu from the top of the screen, then "Add New Tracks". Add up to five new audio tracks. They will display on the left side in the track field. Place the MP3 song on track 1, then right click the song to select "Copy."
Paste the song on track 3, making sure the track is in sync with the song on track 1. Click the "M" button , located in the track field on track 1, to mute track 1. Scroll the start clicker, which is located at the top of the MP3 sample, to the beginning of the song.
Add effects to the MP3 on track 3 by right clicking the sample, then selecting effects such as echo, distortion, reverb and pitch correction. Set the echo and reverb effects between 30-45%, if planning to use them. Place the start clicker at the beginning of the song and press the "Play" button to preview.
Delete the original song on track 1 if you're satisfied with the changes you made on track 3. If you're not satisfied, delete the song on track 3, copy the original from track 1 again and re-edit.
