Upload and Extend Audio API FAQ
What audio file formats are supported for upload?
The API supports common audio formats including MP3, WAV, M4A, and more. Maximum file length is 2 minutes. Files are automatically processed and analyzed for style characteristics before extension.
How do I choose where to extend the audio from?
Use the timestamp parameter to specify the exact point in seconds where extension should begin. You can extend from any point in the audio - beginning, middle, or end. The AI will analyze the audio up to that point to maintain consistent style.
How long can the extended audio be?
Extended portions follow the same length limits as generated music based on model version. V4 supports up to 4 minutes total, while V4.5, V4.5PLUS, V5, and V5.5 support up to 8 minutes total length including original and extended portions.
How does the API maintain style consistency?
The AI analyzes your uploaded audio's musical characteristics including genre, tempo, instrumentation, mood, and production style. The extension is generated to match these characteristics seamlessly, with adjustable style weight for control over how closely it follows the original.
Can I extend the same audio file multiple times?
Yes, you can extend audio multiple times. Each extension is a separate API call. You can also take the output of one extension and use it as input for another to create even longer compositions with consistent style throughout.
