How it works

Turn a cappella into a song in three steps

Upload a clean vocal, pick a style, and generate matching backing. No DAW setup required.

Singer in a home studio adding an AI backing track to a vocal recording

Step 1

Upload your vocals

Use MP3 or WAV, up to 50MB and 8 minutes. Clean a cappella, rap, or spoken word works best. Mixed full songs are not a good fit.

Step 2

Choose style and output

Add a title, style tags like pop acoustic or hip hop, and optional lyrics. Keep vocals plus backing, or export backing only.

Step 3

Generate and download

Most jobs finish in about 1–2 minutes. Sign in first. History on this page stores finished tracks.

Why this tool

Stable backing that still sounds like you

Stable generation

Jobs usually complete without a retry loop. Failed creates refund credits.

High vocal restoration

The original phrasing stays in the mix. This tool adds accompaniment; it does not replace the singer.

Fast turnaround

Most backing tracks are ready in about 1–2 minutes after the task is created.

Two useful outputs

Keep vocals plus backing for a full song, or download backing only for practice and overdubs.

Who it is for

Built for vocalists who already have a take

Singers

You have a clean vocal and want drums, guitar, or piano around it without rebuilding the take.

Rappers

You recorded a verse or hook and need a matching beat, not a new vocalist.

Songwriters

You hummed or sang a voice memo and want a playable sketch before a full production.

Demo producers

You need a fast backing track for rehearsal, pitching, or content, with the original vocal intact.

FAQ

Questions before you upload

What files work for add instrumental to vocals?

Upload MP3 or WAV, max 50MB and 8 minutes. Clean a cappella, rap, or spoken word works best. Mixed full songs with existing drums are a poor fit.

Does this replace my vocal?

No. The generator keeps your original vocal and writes new backing around it. Choose keep-vocals plus backing, or backing only if you want the accompaniment by itself.

Is this the same as an AI vocal remover?

No. Vocal remover extracts stems from a mixed song. This page is an AI accompaniment generator: it creates new backing for a vocal-only recording. If your file already has a full mix, start with AI Vocal Remover.

How much does it cost and is it free?

Sign in to use the tool. New users receive free credits to try it. Each successful create costs 3 credits and usually finishes in 1–2 minutes. Credits are refunded if the task does not complete.

Can I use the result commercially? Is it royalty-free?

Paid users, including subscription users and one-time credit pack users, get commercial usage rights on works generated on AIMakeSong. Those works are 100% royalty-free for commercial projects, including earlier free-plan works after you upgrade. You must own or have permission to use the uploaded vocal. This does not cover copying another artist’s voice or protected material.
