Common questions, answered
Frequently asked questions
How do I make a mashup of two songs for free?
+
Upload one song under Vocals from and another under Beat from. The Mashup Maker separates the voice from the music in both songs in your browser, moves the vocals to the beat’s tempo and key, lines them up on the drums and mixes them with the voice on top. Adjust the levels, key or timing if you like, then download the mashup as MP3 or WAV. It is free with a free account, with no watermark and no limit.
What makes two songs mash up well?
+
Close tempos (within about 10–15 BPM), the same or a related key (neighbours on the Camelot wheel), and one song with a strong lead vocal over another with a strong beat. Classic mashups put an acapella over an instrumental. The tool matches tempo and key for you, so a bigger gap still works, but the vocal sounds most natural when the move is small.
Does it match the BPM and key automatically?
+
Yes. It finds both songs’ tempo and key, stretches and shifts the vocals to fit the beat, and lines them up on the drums. You can still move the key or timing by hand.
Which song should be which?
+
Vocals from: a song with a clear lead singer. Beat from: the song whose music you want. The swap button flips them.
Is it free?
+
Yes, completely free with a free account: no watermark and no limit on mashups or MP3 and WAV downloads.
Can I publish mashups of commercial songs?
+
You need permission from the rights holders to publish or monetise mashups of songs you do not own.
Which files and how long?
+
Audio files you have, such as MP3, WAV or M4A, not YouTube or Spotify links. The first 3 minutes 20 seconds of each song are used.
Does it work on a phone?
+
Yes, in a modern browser. The first run downloads a 172 MB AI model once; splitting is faster on a computer.
Can I mash up two songs from YouTube or Spotify links?
+
Not with links: it works on audio files you have (MP3, WAV, M4A or FLAC). Downloading audio from YouTube or Spotify is against their terms. RaveDJ is the option that starts from links, with little control over the edit.
Does it work without uploading my songs?
+
Yes. Both songs are split and mixed inside your browser, so the audio never leaves your device.
What is the best free mashup maker?
