AI MUSIC EXTENSION
AI Music Extender
Extend songs, beats and instrumentals with AI. Upload your audio, choose a starting point and create the next section.
EXTENSION DESK / 01
Extend an uploaded music idea
Upload an audio draft, choose where the continuation starts, then create the next section in its musical direction.
Music extension uses credits and requires an account. Sign in to continue.
FROM IDEA TO MUSIC
Give your music a next chapter
Start with an audio idea you already have. The music extender creates new material from your chosen point, guided by the sound and direction you describe.
Build another section, explore a new ending or develop a short draft into a longer track. Set the style and choose whether the extension stays instrumental.
MADE FOR YOUR WORKFLOW
Direct the next section
Give the extension a source, a starting point and a purpose.
A precise starting point
Set Continue from in seconds before the source ends. A phrase boundary can be a useful starting point when you want the next section to feel connected.
Creative direction
Use Extension direction to explain what happens next: build energy, reduce the arrangement or move toward an ending. Describe the change rather than only asking for more music.
Style guidance
Use Style guidance for the qualities that should carry over, such as a warm piano lead or steady groove. Keep instrumental selected when the continuation should focus on instruments.
How to extend a song with AI
Continue an existing idea in three steps.
Upload and listen
Choose an audio file and play the area around the intended handoff. Identify a musical phrase or section boundary, then note its position in seconds rather than guessing from the file length.
Set the continuation
Enter the continuation time, describe the next section and add the style qualities to preserve. Set a useful title and check the instrumental option before submitting the request.
Generate and review
Listen across the handoff and through the new material. Check the change in energy, instrumental balance and ending, then save the audio or try a more specific direction.
More room for your musical ideas
Develop an existing track for the project in front of you.
Songwriters
Explore a bridge, another verse or an alternate ending from an existing draft. Describe the role of the next section so the continuation has a musical purpose.
Beat makers
Develop a short idea into another arrangement section. Ask for a change such as thinner drums or added melody while keeping the groove direction consistent.
Video creators
Give a scene more musical development when the first draft ends too soon. Describe the next emotional beat, then trim the result to the edit in your video software.
Music producers
Compare several continuation ideas for the same source. Keep notes on the handoff point and direction so you can identify which version best serves the arrangement.
YOUR NEXT CREATIVE STEP
New music that continues your idea
The extender composes a continuation from the selected point. The source audio, prompt and style work together to guide the next part of the track.
Review the transition and musical direction in the completed result, then use the download action to keep the audio.

Choose where the music goes next
Use your description to guide the new section.
Longer ending
Request a gradual reduction in energy, fewer layers and a clear final phrase. Choose a handoff before the existing ending so the new material has room to develop.
Energy build
Describe which elements should grow, such as percussion or supporting instruments. Keep the style guidance focused on the groove and tonal character you want to carry forward.
Quiet breakdown
Ask for a more spacious passage with fewer active parts. Name the instrument that should remain prominent so the breakdown still feels connected to the source.
Another verse
Describe a return to the main groove with a modest change in accompaniment. Listen for whether the new section leaves the space you need for your own performance.
Instrumental passage
Keep the instrumental option enabled and name a lead part for the new section. Ask for a melody-led passage, a rhythmic interlude or a quieter connecting moment.
Alternative finish
Try a different destination from the same handoff point: a restrained close, a final build or an unresolved mood. Compare the endings against the purpose of the track.
Frequently asked questions
The details to know before you start.
Choose an audio file using the upload field; its accepted types include MP3, WAV, M4A, FLAC and OGG. Preview the source on the page to check the material before selecting the continuation point.
Enter a time in Continue from, measured in seconds. The field accepts 1–480 seconds and the point must be before the source ends. Listen around that position to choose a useful musical handoff.
Yes. Leave Keep the extension instrumental selected when submitting. Describe the instruments and development you want in the continuation, and keep the style guidance aligned with that instrumental direction.
The tool generates new material guided by your source and description. If you only need an exact repeated loop, an audio editor is more direct. Use extension when you want the music to develop into another section.
Yes. Music extension requires sign-in and uses credits. Check the source, time and direction before submitting. When the task completes, review the returned audio in the player and use its download action.
Direction describes the change you want next, such as a quieter breakdown. Style guidance describes what should remain recognizable, such as warm piano and a steady pulse. Using both helps communicate continuity and development.
The page lets you choose where the continuation begins, but it does not offer an exact final-duration control. For a timed video or scene, listen to the result and trim or arrange the audio in your editor.
Try a handoff nearer a phrase boundary and describe a smaller change in energy or instrumentation. Keep the main style consistent, then compare the transition and new section before deciding which version to keep.
