Frequently Asked Questions about Add Vocals API

What types of instrumental music work best with Add Vocals API?

The Add Vocals API works with any instrumental music, but performs best with clear, well-mixed instrumentals that have defined melodic structure. Works excellently with pop, rock, electronic, jazz, and most contemporary music genres. Ensure audio is high-quality for optimal vocal generation.

How do I control what the AI sings?

Use the 'prompt' parameter to provide lyrics or descriptive guidance. You can input exact lyrics you want sung, or provide style/mood descriptions to guide the AI's vocal interpretation. Combine with style parameters and vocal gender selection for precise creative control.

What's the difference between male and female vocal options?

The vocal_gender parameter (m/f) controls the vocal characteristics. Male (m) produces deeper, masculine vocal tones while female (f) generates higher, feminine vocal characteristics. Choose based on your creative vision and how it complements your instrumental track.

Can I adjust how much the style influences the vocals?

Yes, use the style weight parameter (0-1 range) to control style influence. Higher values (closer to 1) make vocals more closely aligned with your specified style. Lower values allow more creative freedom while maintaining general style direction.

How do I get the final audio file with vocals?

After submitting your request, you receive a task_id. Use this to query results via the Query Music Detail API, or set up a callback_url webhook to be automatically notified when your vocal track is ready with download URLs.
