Suno Upload Extend

Extend any audio file (not limited to Suno-generated tracks) using Suno AI.

Overview

Suno Upload Extend takes any audio file via URL and extends it using Suno AI. Unlike the standard Suno Extend node (which requires a Suno Audio ID), this node accepts a raw audio URL, making it suitable for extending audio from any source – uploaded files, other AI-generated audio, or external audio. It supports optional style customization, prompt guidance, and model selection.

Configuration

Field	Type	Default	Description
Model	enum	"V5"	Suno model version: V5, V4_5ALL, V4_5PLUS, V4_5, V4.
Continue At	number (seconds)	0	Timestamp in seconds from which to continue the extension (minimum 0).
Prompt	string (max 3000)	""	Optional prompt describing the desired continuation.
Use Default Parameters	boolean	true	When true, Suno uses its defaults for style-related parameters.
Title	string (max 200)	""	Title for the extended track.
Style	string (max 500)	""	Genre and style tags for the extension.
Negative Style	string (max 500)	""	Styles to avoid in the extension.
Vocal Gender	enum	auto	"male", "female", or unset for automatic selection.

Inputs & Outputs

• Inputs: audio – audio URL from any upstream audio node (upload, TTS, generate music, etc.)
• Outputs: audio – extended audio URL

  Best Practices

• Use this node instead of Suno Extend when your source audio is not from a Suno node.
• Set Continue At to specify exactly where the extension should begin; 0 appends to the end.
• Provide a prompt to guide the continuation style, especially when the source audio has ambiguous direction.
• Toggle Use Default Parameters off to gain control over style, negative style, and vocal gender.
• The source audio must be accessible via a public URL.

Common Use Cases

• Extending uploaded audio files that were not generated by Suno.
• Continuing TTS-generated audio with musical content.
• Lengthening audio from external sources (podcasts, recordings, other AI tools).
• Building hybrid workflows that mix Suno AI with other audio generation nodes.
• Creating extended versions of short audio clips or loops.

Tips

• The key difference from Suno Extend is that this node accepts a raw audio URL (uploadUrl) rather than a Suno Audio ID. Use Suno Extend for Suno-generated tracks and Upload Extend for everything else.
• This is lighter than standard Suno Extend because it does not use the full generation pipeline.
• The Prompt field is optional but recommended – without it, the AI relies entirely on the source audio to determine continuation.
• Style, Negative Style, and Vocal Gender are only active when Use Default Parameters is set to false.
• Connect any audio-producing node upstream (Upload Audio, Text to Speech, Generate Music, Audio Isolation, etc.).
