Get custom audio files from different songs of your choice. To join the songs you can put them one after the other, or you can make them overlap. There are two audio tracks so you can insert pieces of music inside another one. Before you merge the songs, you can do some quick edition such as fade in, fade or trim some undesired parts. If you want to repeat a song several times, you replicate the sound file as many times as you like. You can also copy a piece of the audio signal and paste it wherever you want.
