Upload and Cover Audio API FAQ
What is the maximum audio duration I can upload?
You can upload audio files up to 2 minutes in duration. For longer transformations, consider splitting your audio into segments or using the Extend Music API to create longer compositions after transformation.
How does audio_weight parameter affect the transformation?
The audio_weight parameter (0-1) controls how much of the original audio is preserved versus how much creative transformation occurs. Higher values (0.8-1.0) preserve more original characteristics, while lower values (0.1-0.3) allow more dramatic style changes. Default is typically 0.5 for balanced transformation.
What's the difference between custom mode and simple mode?
Simple mode requires only a prompt describing the desired style. Custom mode (custom_mode: true) gives you full control over audio_weight, style details, title, negative tags, vocal gender, and style weight parameters for precise artistic control.
How well is the original melody preserved?
Suno's AI technology is designed to preserve the core melody while transforming the arrangement, instrumentation, and genre characteristics. The melody preservation quality depends on audio_weight settings and the complexity of the original audio.
Can I transform vocals into different singing styles?
Yes, you can transform vocal performances into different singing styles and genres. Use the vocal_gender parameter to specify the desired vocal characteristics, or set vocal to false for pure instrumental outputs.
What audio formats are supported for upload?
The API accepts common audio formats including MP3, WAV, and other standard formats. Ensure your audio is clear and well-produced for the best transformation results.
