Three simple steps

How to use the AI Song Extender in three steps

  1. 01

    Upload with rights

    Start with music you own or are authorized to use. Your file uploads privately only when you generate. The AI Song Extender checks the submitted source again before it creates a private task or reserves credits.

  2. 02

    Place the tape head

    Preview the source and drag the marker to the exact moment where the new composition should begin.

  3. 03

    Direct and review

    Guide style or lyrics, then play and download either complete variation independently.

Practical AI extension guide

How the AI Song Extender works with real music

Use the source as the musical reference, choose the exact handoff, and describe what should happen next. The continuation should develop new material rather than repeat a loop, and both complete versions should be judged at the same transition points.

01Choose a musical handoff point

Do not automatically place the marker on the final silent frame. A small amount of active musical context before the handoff helps the continuation follow the rhythm and direction. A point inside the last phrase, groove, or sustained chord usually works better. For a verse-to-chorus transition, place the marker where the arrangement is already preparing to lift. For an outro, keep enough music before the marker to preserve the groove, then describe how the energy should resolve.

02Write a direction that complements the source

A style direction is most useful when it describes the next section rather than rewriting the whole song. Mention the intended section, energy curve, key instruments, vocal presence, and transition. For example, ask for a restrained bridge that keeps the same drums and bass before opening into a wider final chorus. Avoid stacking unrelated genres or contradictory tempo instructions. The AI song extender already receives the source audio as its main reference, so the text should clarify what changes next and what must remain stable. Short, concrete production language is easier to evaluate than vague praise words. This keeps the AI song extender focused on one audible change.

03Compare candidates at the transition

The first seconds after the continuation point matter more than an impressive ending. Listen for timing drift, a sudden key change, altered vocal identity, a mismatched room sound, or a hard edit at the handoff. Then review whether the new section develops the intended musical idea. The AI song extender keeps candidates separate so you can audition each result without overwriting the upload. A practical extender should make those comparisons easy. If neither candidate is usable, adjust one variable at a time: move the marker slightly earlier, simplify the direction, or change the lyric density. This makes the next generation a controlled iteration instead of a random restart.

Made for a real handoff

What this AI song extender keeps under your control.

01

Continue from the exact musical moment

Click the waveform to move playback, then set the independent handoff marker by dragging it, entering seconds, moving ±5 seconds, or using the current playback position. The AI Song Extender uses that saved point as the requested boundary between the owned source and the new section.

Start simple, open deeper controls when needed

Simple keeps the essential controls. Custom adds a song title, vocal choice and more production detail without clearing the draft.

Compare, save, and download both complete results

One successful generation returns independent A and B versions. Preview both at the same musical moments, then save or download the stronger result when your account has access.

Where an AI song extender fits real creative work.

Songwriters & independent artists

Develop a demo into a bridge, final chorus, instrumental passage, or more deliberate ending.

Video editor fitting music to a longer scene timeline

Video & film editors

Create a musically developed cue that can better fit a longer scene or edit. The AI Song Extender can carry an owned cue beyond its original ending while keeping the editor in control of the handoff point and final choice.

Podcast producers

Give an owned intro, outro, or music bed enough room for the episode without an obvious repeat.

Rights & privacy

Your permission is part of the product, not fine print.

Source privacy and result visibility

Your source stays private. Result visibility is shown before generation. Local preview does not upload the file before you generate.

Source rights remain yours

A commercial AI song extender plan cannot grant rights to third-party material inside an upload. Only use audio you can legally extend.

Charge on success

The current song workflow reserves credits and releases them when generation fails.

Before you upload

Questions before you upload

What audio can I choose?

Choose MP3 audio you own or are authorized to use. SongExtender V3.5 and V4 accept sources up to four minutes; V4.5, V4.5+, V5, and V5.5 accept sources up to eight minutes. The exact limit updates when you choose a version.

Does this page send my audio anywhere?

No. File selection and playback stay in your browser while generation is unavailable.

Will the result be a repeated loop?

No structural looping is used. The service follows the source and exact continuation point, then returns newly generated extended tracks. Musical quality still varies by source.

Can I use a future result commercially?

Only if you have the required source rights and the applicable output terms allow your intended use. Review the Terms before publishing.

Can I extend instrumental music?

Yes. Every SongExtender version offers a manually selected Instrumental mode, with a four- or eight-minute source limit depending on the version. It is never used as an automatic paid retry.

Which output formats are available?

Both lyrics-guided and instrumental results download as MP3 files. When conversion is needed, the browser prepares the MP3 before saving.
