Make a mashup in
Mixed In Key's Mashup Software

Analyze your favorite MP3 files

First, build your library of audio files and songs you want to blend together to create your mash up. Drag files from a browser or iTunes into the program. Mashup Software quickly begins to analyzes the tracks and organize them.

Add your first track

Load up the first track by clicking the blue add button in the browser. As the song loads up, you’ll see the waveform of the track represented by the blue and white graphics. The blue represents the melodic and harmonic content, while the white represents the drums and beat of the song.

Find the best match

Next, we look back down into the browser and sort them by Harmonic Compatibility. Mixed in Key’s algorithm has analyzed our tracks, sorting them into their respective keys and tempos.

The harmonic compatibility works on a 0-100 scale where 100 represents a track that is perfectly in key with our starter song, and a 0 representing a song that will be completely disharmonic.

Choose your pair

In this case I chose an “Emotions” by Destiny’s Child acapella, paired with Pretty Lights’ “Pop Quiz” as our starting song. Pop Quiz’s tempo is 105, while Emotions sits at 87 BPM. The two songs will automatically be warped and beat matched in respect to the projects master tempo.

Set the tempo

Next, I will change the projects master tempo to 95, as I find it’s a good medium between the two tracks. To do this, click the small wrench icon in the top bar and edit the master tempo to your choosing.

Zoom in to edit

From here, we can zoom in more to fine edit the beat matching and sync using the zoom icons in the top bar. We can drag the file around, cut, edit, copy, and manipulate the file as we see fit.

Mix using volume and EQs

Finally you can dial in the sounds you want by manipulating the volume, panning, and EQ levels. If you have 3rd party VST plugins already installed you can add them to each track as well to help dial in the final results you're looking for.

Save your Mashup to MP3

Save the project for further editing, or export straight to audio.
