How to make a song mashup

Quick answer: To make a song mashup, add 2–4 songs, choose the part of each song, match the tempos, pick a style and listen.

  1. Add 2–4 songs. Each song's tempo (BPM) is detected as it loads.
  2. Choose the part of each song. Drag the two handles on each waveform to the section you want, for example a chorus.
  3. Match the tempos. Press Match tempo on songs 2–4 so they play at the same BPM as song 1.
  4. Pick a style. One after another blends each part into the next with a crossfade; Layered on top plays parts at the same time from their own start points.
  5. Listen. Press Preview mashup to hear it on the page. It keeps playing if you switch tabs or lock your phone, and the lock-screen buttons pause and skip.

Sequence or layered mashup?

A sequence mashup is the easiest: chorus of song A, crossfade, verse of song B, and so on, like a DJ mix. A layered mashup puts two songs on top of each other, typically the vocals of one over the instrumental of another. For layering, cut the bass on the vocal song and soften the highs on the beat song so they don't fight.

Why match the tempo?

Songs at different speeds drift apart and sound messy when they overlap. Matching playback speed lines up the beats. This tool changes speed the classic way, so pitch moves too: keep changes small (within about ±8%) to avoid voices sounding odd, and choose songs with similar tempos.

Frequently asked questions

How many songs can I mix?

Up to four songs, with a total length of up to 15 minutes.

Does it detect BPM?

Yes. Each song's tempo is estimated from its beat pattern; it works best on songs with a clear drum beat.

Can I download the mashup?

No. Mashups play on this page only, so you can listen as often as you like (also in the background or with your screen locked) but there is no download. To keep a single song with an effect, use the Slowed + Reverb Maker.

Is my song uploaded?

No. The audio is decoded and processed by your own browser with the Web Audio API. The file never leaves your device.

Can I post the result on TikTok, Instagram or YouTube?

Only if you have the rights. Editing a song doesn't make it yours: use your own music, royalty-free tracks or songs you have permission to remix, and follow each platform's music rules. For personal listening, it's yours to enjoy.
