Overview

ExtendMusic.AI is a web-based generative music tool that extends an uploaded audio clip with AI-generated material. The product page describes it as a way to create and extend music, explore new sounds, and enhance original compositions.

In the app, users select a file, choose a context segment of at least 10 seconds, set the extension length, and optionally add a prompt before generating the audio extension. The available controls point to a guided workflow for continuing an existing musical idea rather than starting from scratch.

Features

Audio input upload

Upload an existing audio file and use it as the starting point for a generated extension.

Context-based generation

Select at least 10 seconds of context to anchor the generated continuation.

Extension length control

Set the number of seconds to extend the selected audio, so the output length is controlled before generation begins.

Prompt conditioning

Add a text prompt to condition the generated music and steer the result toward a desired direction.

Creativity control

Adjust creativity to influence how diverse or exploratory the generated output should be.

Prompt influence control

Adjust prompt influence to change how strongly the prompt affects the generated result.

Use cases

Extend a work-in-progress track
Continue a musical sketch or demo by uploading a clip, selecting a section of context, and generating additional measures or seconds beyond the original ending.
Explore alternate musical ideas
Experiment with different continuations by changing the prompt, creativity, and prompt influence controls to compare generated directions.
Build variations from an existing piece
Use an existing composition as the base for a new variation, keeping the original material intact while generating an extension that follows the same musical context.
