Remixing your song's vocals onto a new instrumental track or mashing them up with other songs can breathe new life into your music. You can cross genres or mix a song's vocals with a revision of the song's instrumental track. Whether you want to mix two tracks of separate or matching tempos, you can mix your vocals to new tracks with free software on your computer.
Align the start of your vocal track's waveform with the point in the instrumental track where you'd like the vocals to come in.
Use Mixcraft's playback controls to preview your track. Hold down the "Ctrl" button on your keyboard while dragging the right end of your vocal or instrumental track. The selected track will expand or compress, depending on the direction you drag the track end. Adjust the selected track so that it syncs up with the other.
Click on Mixcraft's "File" heading. Highlight the "Mixdown" option in the File menu, and then select an output audio format for your mixed track.
