more song, same identity

Continuation instead of regeneration

Pick where the track should continue and let SeedAudio write the next section in the same sound.

Regenerating a song to make it longer usually changes everything you liked about it. Extending keeps the existing audio and only adds what comes after, which protects the parts you already approved.

You can extend more than once, building a longer arrangement section by section, and stop when the song has the length and shape you need.

Continuation instead of regeneration

Tracks run short for all kinds of reasons: a generation stopped early, a loop needs to cover a longer video, a song needs one more chorus. The extender continues the audio from the point you choose instead of starting again.

The continuation keeps the tempo, instrumentation and character of the source, so the join sounds like part of the same recording.

Why extend on the bench

Choose the continuation point

Start the new material from a moment you pick, such as the end of a strong chorus, rather than only from the final second.

Style carried forward

The extension follows the existing groove and sound palette so the transition stays natural.

Chain several passes

Extend the extended version to build intros, bridges and outros step by step.

Making a track longer

Making a track longer

Listen for a natural phrase ending before you choose where to continue.

  1. 1

    Select the song

    Pick a track from your library or upload one you want to lengthen.

  2. 2

    Set the starting point

    Choose where the continuation begins, ideally at the end of a phrase or section.

  3. 3

    Audition the join

    Play across the transition and keep the version where the seam is hardest to hear.

When a song needs more length

Video soundtracks

Stretch a track to match the length of an edit without looping the same bars.

Fuller song structure

Add a second verse, bridge or final chorus to a short idea.

DJ and live edits

Create longer intros and outros that give room to mix in and out.

Clean extensions

Continue from a phrase end

Joins placed mid-phrase are more noticeable. Pick a bar where the music breathes.

Describe the next section

If you want a bridge or breakdown, say so; otherwise the extension will tend to continue the current section.

Check the whole version

After several passes, play the full track to make sure the overall structure still makes sense.

Extender questions

Does extending change the original part?

The goal is to keep the source audio up to your chosen point and add new material after it.

Can I extend an uploaded song?

Yes, provided you have the rights to adapt it. Library tracks can be extended directly.

How many times can I extend a track?

You can extend repeatedly; each pass uses credits and builds on the previous version.

Will the extension match the vocals?

It follows the style of the source, including vocal character where present, but always audition the join carefully.

Give a short track more room

Pick the moment where your song should keep going and hear the continuation.
