capfuse: Mashup & Remix Maker

Make a mashup in 30 minutes — even if you have never DJed. capfuse analyzes your tracks, tells you which ones fit together, and takes care of tempo and timing. You decide which phrase goes where — capfuse makes sure it lands on the beat. WHY MASHUPS ARE HARD — AND WHY THIS IS NOT Blending two songs normally means knowing music theory, matching keys by ear, and nudging tempos until they lock. capfuse does all three for you. AUTOMATIC KEY AND BPM DETECTION Import from your music library or from files. Every track is analyzed and tagged with its key and tempo. Video files such as mp4 work too — the audio is extracted automatically. COMPATIBLE TRACK SUGGESTIONS Pick a base track and capfuse lists the songs in your library that are harmonically compatible with it. No Camelot wheel, no guesswork. Choose from what already works. AUTOMATIC BEATMATCHING Tempos are synced for you. Decide which phrase goes where and capfuse handles the alignment. BUILT-IN LIBRARY Finished mashups are saved to your library and play back like any music app, including background playback. FREE TO START Import tracks and build mashups for free. Upgrade to premium for unlimited assets and unlimited mashups. Made for anyone who has ever heard two songs and thought "those would go together."
