Audacity is sound-editing software available free of cost online. The program can be easily downloaded onto your computer and is a useful tool to edit audio clips. Overlapping two audio clips is a relatively simple task using Audacity. When two or more audio clips are overlapped and exported as a single audio clip, the sounds from both clips are played simultaneously.
Step 1
Launch Audacity and open one of the files you wish to overlap by clicking the "File" menu and clicking "Open."

Click and drag the tracks horizontally to adjust the positions of the audio clip relative to one another.

Click the "Play" button at the top of the screen to hear what the overlapped audio sounds like, and adjust the positions of the audio clips accordingly.
