What the tool does

Add another section without losing the source

Start from a library song or supported upload, then listen closely to how the added audio joins it.

Choose a song or upload audio

Start from a MusicWave library track, or upload MP3, WAV, or M4A audio within the current limits.

Set the continuation point

Choose the moment near the end or inside the source where the added section should begin.

Describe what happens next

Add a plain direction for the instruments, energy, lyrics, or ending you want in the new part.

Continue in context

The tool uses the source before the chosen point as context for the added audio.

Compare another take

Try the same continuation again or change the direction when the first return does not fit.

Keep the longer version

Play the returned song, save it to your library, and download the version you prefer.

Three steps

Choose the source, set the continuation point, and describe what comes next.

Choose the source

Select a library song or upload a supported audio file up to the current length limit.

Set the point and direction

Choose where to continue and describe the instruments, mood, vocals, or ending.

Generate and review

Confirm the 10-credit cost, start the extension, and listen around the join.

Before you start

Describe the job of the next section

A chorus return, breakdown, extra verse, or clean ending is clearer than a vague request to make it longer.

Choose a useful continuation point

A clear phrase ending, held chord, or transition often gives the next section more musical context.

Name the job of the new section

Ask for another verse, a chorus return, an instrumental break, a build, or a clean ending.

Listen closely at the join

The new audio may differ in voice, mix, harmony, or timing. Compare takes before keeping one.

Ways to use it

Continue the arrangement where it needs more room

Add another verse or chorus

Continue a short song when the arrangement needs one more repeat or lyrical section.

Build a longer instrumental

Add a breakdown, solo, ambient passage, or repeated groove to background music.

Create a cleaner ending

Ask for an outro or final cadence instead of letting the track stop abruptly.
