Download and install a program that supports multi-track recording if you do not already have this type of software on your computer. This would include most major digital audio workstations, such as Garageband, Mixcraft, Audition, Logic, Pro-Tools and Cubase. Free multi-track programs also exist (see Resources).
Create a new audio project. Open your software, click “File” on the menu bar and select “New” from the drop-down menu. It may also read “New Project” or “Create New Project.” When you select this object, a pop-up menu may appear, asking you to enter a title for your project along with other basic information, such as your desired key and tempo (speed). To figure out the tempo of your selected songs, indicated by beats per minute, listen to the song for exactly 15 seconds and count the number of beats. You can clap or tap your foot if it helps. Multiply the number of beats by four to get your tempo in beats per minute. For best results, choose two or more songs with very similar tempos for your mix.
Drag your first audio file onto the first track on your screen. Your tracks look like long, blank horizontal spaces (or bars) beginning at the top of your screen and continuing to the bottom. To import a song onto a blank track, drag the file with your mouse and place it at the very beginning of the track space, on the left side. Place your second song file on the second track, and any subsequent song files on the following tracks.
Remove the parts of each song that you do not want. For a chorus mix, you will want to remove the verses, bridge, intro and other non-chorus aspects. Locate the section of the recording you want to save, and click your mouse at the “Start” point of your chorus to place the time line indicator in that spot. Then locate the “Split” or “Cut” button on your project window (sometimes indicated by a pair of scissors) and click it once to separate your chorus from everything that comes before it. Sometimes the option may appear on your menu bar, under the “Edit” menu or “Tools” menu. After you split the “Start” point of your chorus, do the same to the “End” point. Then highlight the regions appearing before and after your chorus and press “Delete,” saving only your chorus. Repeat this for all of your song files.
Drag your choruses along the time line and place them in the order in which you want them to appear. If you place the choruses directly on top of one another in their respective tracks, they will play simultaneously. If you separate them along the time line, they will play separately. For example, you may begin your first chorus, on track 1, at “0:00” on the time line, and end it at “0:45.” Then begin your second chorus, on track 2, at “0:46” and end it at “1:15.” To create a duplicate of a chorus, click it once to highlight it, then click "Edit" on the menu bar and select "Copy" from the drop down menu. Then drag the time line cursor to the point in the song where you want your chorus to repeat, and click "Edit" on the menu bar followed by "Paste." You can repeat your choruses as many times as needed.
Use your “Effects” options on your screen to add effects to your mix, and save by clicking “File” on the menu bar and selecting “Save” from the drop-down menu. When asked to select an audio format, choose a common format like WAV or MP3.
