Music FX
Extend your music tracks with generative AI: new music that continues from the point you choose, not a loop.
Select the timestamp to start extending from
Select a track and click Extend to create your first extension.
Set the continuation point in seconds: it must be at least 1 second and before the end of the source audio. Choose a point near the end of a phrase so the AI has useful context. For a MusicFX source song, you can reuse the original parameters or supply new style and lyric instructions. The AI aims to follow the source, but the voice, rhythm or instrumentation can change. Preview the join; a seamless match or an exact final duration is not guaranteed.
Our AI music extender uses generative AI to continue your track from a point you choose, taking its tempo, key and style into account. Unlike loop-based tools that repeat the same section, it generates new material that follows on from your original. Use it to lengthen a short demo, add an intro or build out a section. It works across genres from electronic dance music to orchestral pieces; listen to the results and keep the extension that fits your track.
AI music extender features for music production, content creation and longer edits.
Use the continuation slider to select a point at least 1 second into the audio and before its end. That point is sent to the generator as the start of the continuation; try a phrase boundary and listen to the join.
The AI continues from your chosen point using the audio before it as context
The source and your instructions guide the result. For songs generated here, reusing original parameters can help preserve the direction, but the AI may change the voice, rhythm or instruments. Preview before downloading.
