Mureka V7.6 Extend Song | AI Music Generation API

Mureka AI V7.6 Extend Song

Mureka AI V7.6 Extend Song extends an existing song or audio track by generating a new continuation segment from the head or tail, guided by provided lyrics. It is suitable for song continuation, outro generation, intro extension, and other music editing workflows where you want to expand an existing track instead of generating a new one from scratch.

Why Choose This?

Song continuation workflow Extend an existing audio track with newly generated music and vocals.
Head or tail extension Choose whether to extend from the beginning or the end of the source audio.
Lyrics-guided extension Provide lyrics for the new segment so the continuation matches your intended content.
Precise extension point control Use extend_at to define where in the source audio the extension begins.
Flexible output formats Export the extended result as mp3, wav, or flac.
Simple pricing Uses a fixed per-request price.

Parameters

Parameter	Required	Description
audio	Yes	Source audio URL to extend. It will be uploaded to Mureka as audio.
lyrics	Yes	Lyrics for the extension segment.
extend_at	Yes	Extension position in milliseconds. This specifies where the extension starts in the source audio.
extend_type	No	Whether to extend from the `tail` or `head` of the source audio. Default: `tail`.
output_format	No	Output audio format after re-uploading to WaveSpeed CDN. Supported values: `mp3`, `wav`, `flac`. Default: `mp3`.

How to Use

Upload your source audio — provide the existing song or audio track you want to extend.
Write the extension lyrics — enter the lyrics for the new segment.
Set extend_at — define the position in the source audio where the extension should begin.
Choose extension type — use tail to extend from the end side of that point, or head to extend from the beginning side.
Choose output format — select mp3, wav, or flac.
Submit — run the model and download the extended song.

Example Use Case

Extend a demo track from the chorus section by adding a new lyrical outro while keeping the existing song structure and tone.

Just $0.036 per generated extension.

Billing Rules

Each extension request costs $0.036
extend_type and output_format do not affect pricing

Best Use Cases

Song continuation — Add a new ending or next section to an existing track.
Intro or outro generation — Extend the front or back of a song with new material.
Demo finishing — Turn partial song ideas into more complete structures.

Creative experimentation — Try alternate continuations from a chosen point in the song.

Pro Tips

Use lyrics that match the tone and structure of the existing audio for smoother continuation.
Choose tail when you want to add a new ending or next section.
Choose head when you want to generate an intro or earlier lead-in material.
Use wav or flac when you want higher-quality outputs for further production work.
Make sure the source audio is clear and complete enough around the extension point for better results.
