Long-form tracks that keep developing
Extension is judged on whether the added minutes are worth hearing. These are the long arrangements the generator produces when length is the point.
Extend songs from a real source track
AI Music Extender starts from uploaded audio or a saved Aimusicis track, then asks for the musical direction that should come next. It is built for users who like an existing section and need a coherent continuation.
Start from existing audio
Paste an uploaded audio URL or choose from My Music before submitting, so the extension has a concrete song to continue.
Shape the continuation
Use the direction, style, title, and optional lyrics fields to decide whether the next section should build, resolve, repeat, or shift energy.
Keep production moving
Send strong extensions into cover, stem, mastering, MIDI, or music-video workflows once the new section fits the source song.
How AI Music Extender works
How to extend a song with AI
Use the generator like a continuation brief: source track first, direction second, then review the extended result before polishing.
1
Add the source song
Upload audio or choose a finished track from My Music. The generator blocks empty submissions because extension requires source audio.
2
Describe the next section
Tell Aimusicis whether to add a chorus, outro, bridge, instrumental break, or a natural continuation in the same style.
3
Add optional lyrics
Paste lyrics when the continuation needs specific words, hooks, or section labels instead of a purely instrumental extension.
4
Continue production
Use mastering, covers, stems, or visualizer tools when the extended track is ready for finishing.
Controls built for continuing songs
The page focuses on source-aware extension controls rather than a generic prompt-only generation box.
Source-audio required
The submit flow validates that a pasted audio URL or My Music selection exists before sending the request.
Style and lyric guidance
Use style and optional lyrics to keep the next section aligned with the original song.
Connected music workflow
The generated extension remains compatible with the rest of the Aimusicis music, stems, mastering, and video tool chain.
The join is the only hard part

Where extension succeeds or fails; everything else follows from it.
3 things
Key, tempo and the instrumentation already playing all have to carry over.
0 change
The original section stays exactly as you uploaded it.
6 upload formats
MP3, WAV, OGG, M4A, FLAC, AAC - accepted for the piece you want continued.
Who needs a track to run longer
Video editors short by thirty seconds
A cut almost never lands on the length of the music. Extending the track beats looping a bar and hoping the seam is invisible.
Producers with a loop and no arrangement
A four-bar idea that works is not a song. Extension writes the sections around it instead of asking you to arrange from scratch.
Streamers and venues needing length
Background music judged over an hour needs to keep moving. Extending a piece you already like beats queueing the same loop twenty times.
