What you’ll need
- Two songs — one you want the vocal from, one you want the music from.
- An acapella from the first and an instrumental from the second (both free to extract below).
- Somewhere to layer them — a DAW, or StemConsole’s built-in mixer for a quick blend.
Beginner tip: pick two songs that are already close in tempo and key. It makes everything after this dramatically easier.
Step 1 — Get the acapella
Run the first song through the vocal remover and keep the isolated vocal — that’s your acapella. (Full guide: how to remove vocals from a song.) The cleaner the source, the better it’ll sit on top.
Step 2 — Get the instrumental
Run the second song through the instrumental maker and keep the instrumental. This is the bed your acapella will sing over.
Step 3 — Match key and tempo
Find the BPM and key of both tracks. Time-stretch the acapella to the instrumental’s tempo so they lock in time, then pitch the acapella so it’s in the same (or a compatible) key. Even a semitone off will clash — trust your ears here.
Step 4 — Blend and balance
Layer the acapella over the instrumental and balance the levels so the vocal sits in the mix, not on top of it. A little EQ to carve space for the voice and a touch of reverb to glue them together goes a long way. Bounce it — that’s your mashup.
Tips for clean mashups
- Use the highest-quality source files you can — better separation, better blend.
- Audition the acapella solo first to catch any artefacts before you build around it.
- Don’t fight a bad key match — try a different pairing instead.
A note on rights
Mashups use copyrighted recordings. Making one to practise or share privately is common, but releasing one commercially usually needs permission — respect the original artists before you publish.
Frequently asked questions
What do I need to make a mashup?
Two songs, an acapella from one and an instrumental from the other, and something to layer them — a DAW, or StemConsole's built-in mixer. You can pull both the acapella and the instrumental for free with a vocal remover.
How do I match the key and tempo?
Find each song's BPM and key, then pitch and time-stretch the acapella to match the instrumental. Pick two songs already close in tempo and key to make this easier.
Is it legal to publish a mashup?
Mashups use copyrighted recordings, so publishing commercially usually needs permission. Making one for practice or private use is common, but respect the rights of the original recordings before you release anything.
