AI Music Extender
What is an AI music extender?
The AI music extender creates the next section of a track you already have. Upload MP3, WAV or another supported format, or choose a finished song from your RaoMusic library. You decide where the continuation begins. Sign-in is required; free accounts get 50 credits every month.
No subscription required
Sign in to extend a song. Extending is available on the free plan — you do not need a paid subscription.
Commercial use included
Songs you made on RaoMusic can still be used commercially after you extend them, even on the free plan. For uploaded audio, you need the rights to the original.

Extend vs repeating a clip vs a new prompt
Extend writes new audio after a keep point. Repeating a clip cycles the same bars. Generating from a prompt starts a different track.
| Feature | AI music extender | Repeating a clip | Generate from a prompt |
|---|---|---|---|
| Starting point | An uploaded file or a library song | The same clip, reused | A text prompt, not the original audio |
| What you get | New audio after the keep region | Existing bars repeated | A new song, not a continuation |
| Where it continues | KEEP / RECREATE on the waveform | No split — it repeats | No original to keep |
| Commercial use on the free plan | Yes, for songs made on RaoMusic | Depends on the source file | Yes, on the free plan |

How to extend a song with AI
Three steps from a short track to a longer one — no DAW required.
- 1
Upload or choose a song
Sign in, then upload an audio file or pick a completed song from your library. Common formats up to 50MB work.
- 2
Set the extend point
Drag KEEP / RECREATE on the waveform so the original stays up to your split and the model continues after it.
- 3
Generate, preview, download
Generate the continuation, preview the versions in your library, then download the MP3. You can extend again from the new track.
When to use an AI song extender
Use it to continue a track you already like. Skip it when you need a short social clip or a DAW-level mix.
Best for
- ✓A demo that ends before the chorus
- ✓A verse that still needs another section
- ✓An uploaded MP3 that should continue past its current ending
Not for
- !Repeating the same bars unchanged
- !Trimming a song to a short social-clip length
- !Replacing a DAW for mixing, mastering, or sample-accurate edits
How an AI song extender continues your track
People reach for a music extender when a demo is too short, a verse still needs another chorus, or an uploaded MP3 should keep going. Because you can upload an existing file, the starting point does not have to be a song originally created on RaoMusic — a way to extend music without rebuilding the track from a blank prompt.
Extending writes new audio after the region you keep, so the song moves forward. It is not a trimmer for short social clips: each run produces a normal generation-length continuation you can take further.
For the smoothest result, put the split at the end of a phrase or bar, not in the middle of a word. If the first take doesn't fit, move the split slightly or generate again; each run gives you two versions to compare.
AI music extender FAQ
On the default model, each extension costs 20 credits and gives you two versions. Premium versions such as Rao v2.0 and Suno v6 cost 30 credits and need a subscription. Free accounts get 50 credits every month, and failed generations are refunded.
Yes. Sign in to upload audio or pick a song from your library. You can extend without a paid subscription.
Both. Upload MP3, WAV, OGG, M4A, FLAC, or AAC up to 50MB, or choose a completed song from your RaoMusic library. Uploads are saved as library tracks you can extend again later.
No. The model writes new audio after the region you keep. It does not cycle the same bars.
Yes. Before you generate, you can edit the lyrics and style for the new section. Keep them close to the original for a smooth continuation, or change them to move into a new chorus, bridge or ending.
Yes, if the original is a song you made on RaoMusic: extended tracks can be used commercially, even on the free plan. If you extend audio you uploaded, you need the rights to that original, and no license certificate is issued for it. See the commercial license page for the full terms.
MP3, WAV, OGG, M4A, FLAC, and AAC, up to 50MB. The file must have a readable duration — a damaged or empty file is rejected before upload.
There's no fixed total length. Each run keeps your track up to the point you mark and writes one new section after it. To make the song longer, extend the new version again, and repeat until it's the length you need.
Yes, you can extend on the free plan without a subscription. Free accounts get 50 credits every month, and one extension on the default model costs 20 credits for two versions. Failed generations are refunded.
Both can extend songs, including audio you upload. The difference is licensing: on RaoMusic, songs you make can be used commercially even on the free plan, extensions included, while Suno limits commercial use to its paid plans. On either service, extending uploaded audio requires the rights to the original.
