ExtendTwo ways to extend your song

Extend a song with AI, make it longer.

Use our AI song extender to extend a song: upload a track up to 4 minutes, mark where it should keep going, and get two extended versions that pick up the same voice and sound.

How to extend a song with AI

  1. 01

    Bring a track

    Upload a song up to 4 minutes, or pick one you already made.

  2. 02

    Set the starting point

    Drag the line to where the new part begins. Preview the cut before you commit.

  3. 03

    Pick a continuation

    Every song extension returns two takes. Play both and keep the extended song that flows.

One short song, three ways to extend a song

Play the original, then the AI-extended song. When you extend a song, the new part starts where the original stops and keeps the same voice and sound.

    Neon Static Hearts

    Keep the same groove, add one more verse, then lift into a bigger final chorus with stacked harmonies

When you need to make a song longer

Need to make a song longer or extend a song with AI? Find the situation closest to yours, copy the direction into Where It Goes Next, and change a few words. Each song extension starts from your own track.

  • An acoustic guitar, a laptop showing a waveform that continues past a cut line, a notebook and a glowing blue vinyl record on a wooden desk

    Songwriters with an unfinished idea

    You have a verse and a chorus that work, but the song stops before it goes anywhere. Extend the song to hear a bridge before you write one.

    Drop into a quiet, half-time bridge with just piano and voice, then bring the full band back in
    Two bridges to react to, in the same voice as your demo
  • A phone on a tripod showing a video timeline where a short clip continues into a longer audio waveform, with a ring light and headphones

    Video creators

    The track you love runs 45 seconds and your edit runs three minutes. Looping it makes the seam obvious, so extend the song instead.

    Keep the same mood and tempo, add a gentle build in the middle, then wind down to a soft fade-out
    An extended song that grows with your footage instead of repeating
  • A podcast microphone, a game controller, a laptop with a two-colour waveform, headphones and two glowing vinyl records

    Streamers and podcasters

    Your intro or background bed is a short loop, and it gets tiring after the first few minutes on air.

    Continue the same groove for another two minutes, keep it instrumental and calm so it sits under a voice
    A bed that lasts the whole segment without pulling attention from you
  • Ballet shoes, a speaker, a stopwatch, a photo frame and a wrapped gift under a glowing pink and orange vinyl record

    Dancers, teachers and gift makers

    A routine, a slideshow or a surprise for someone has a fixed length, and the song you made is shorter than that. Make the song longer to fit.

    Add one more verse, then lift into a bigger final chorus with stacked harmonies and a clean ending
    A song that fills the whole moment and finishes on a proper ending
Better first takes

Pick the cut, then say where it goes

To extend a song well, the cut point decides how the AI-extended section joins your song. Start from what you want to hear next.

What do you want next?

Give it a real ending
From the end of the track
“Wind down with a long outro, strip layers away, finish on a soft fade-out”
Build to a bigger final chorus
Right after a chorus finishes
“Add one more verse, then lift into a bigger final chorus with stacked harmonies”
Add a bridge for contrast
Right after the second chorus
“Drop into a quiet, half-time bridge, then bring the full band back in”
Make a song longer with an instrumental
At the end of a full loop of the groove
“Keep the same groove and mood, add a gentle build in the middle, then settle”

Write the direction

Too open

Make it longer and better

Easy to follow

Keep the same groove, add a second verse about leaving town, then build into a bigger final chorus

  • Cut where a phrase has just finished, such as the end of a chorus or a bar line. Cutting in the middle of a word asks the extension to finish someone else's sentence.
  • Use Hear the cut before you generate. It plays the last few seconds up to your line, so you can judge the seam.
  • Say what the new part should do: keep the energy, rise, fall or resolve. One clear job beats a long list.
  • Compare both extended versions. If neither lands, move the cut a bar earlier or later and extend the song again rather than rewriting everything.
Looping, slowing down and extending with AI compared
Way to go longerWhat it doesGood forKeep in mind
Loop itRepeats the same audio again and again.Fast filler for a steady beat.Nothing new happens, and the seam shows.
Slow it downTime-stretches the song so it lasts longer.Small length changes.Tempo and pitch feel drop, vocals sound off.
Extend a song with AIThe AI song extender writes new music from your cut point, with optional lyrics.A new verse, bridge, chorus or ending.The result is new, so compare two versions.

Extend a song with AI in three steps

  1. 01

    Bring a track

    Upload the song you want to extend, up to 4 minutes, or pick one you already made in My Music. The AI song extender works from that track.

  2. 02

    Mark where it continues

    Move the pink line, or press From the end, to choose where the song extension starts. Add a direction or lyrics for the new part if you want a say.

  3. 03

    Pick your favourite take

    Every AI song extension returns two extended versions. Play both, then keep the extended song that fits or adjust the cut and extend the song again.

What to bring to extend a song

One track and one cut point are enough to extend a song. Everything else is there when you want more say over the song extension.

  • Sing lyrics you wrote for the new section, with [Verse] or [Bridge] tags.
  • Return two extended versions to compare, saved to your workspace.
  • Extend a song up to 4 minutes, uploaded or picked from My Music.
  • Make a song longer without a repeat, and give your credits back if a song extension fails.

What it can't do

  • Start a song from nothing. To extend a song you need a source track.AI Music Generator
  • Change the style of the whole song. Extend adds a new part and keeps the rest.AI Remix
  • Replace a section in the middle. The new part begins at the point you pick.
  • Extend a song longer than 4 minutes. Trim it first.
