SunoAPI
Vocal Music Generation
This flagship feature lets you generate complete songs with vocals directly from a text description. You can specify the genre, mood, theme, and even language to create a custom track. It's perfect for creating original songs, jingles, or background music with lyrical content without needing a singer or songwriter. The API supports various models to fine-tune the output to your exact creative vision.
Instrumental Generation
Need a killer beat or an atmospheric score without words? The Instrumental Generation feature creates rich, studio-quality instrumental tracks. Describe the vibe you're after—like "epic cinematic trailer music" or "chill lo-fi study beats"—and get a ready-to-use track. This is ideal for game developers, video editors, and podcasters who need specific moods without the complication of vocals.
Music Editing & Manipulation
SunoAPI goes beyond simple generation with a suite of powerful editing tools. You can extend the length of an existing track, replace specific sections, swap out instruments or sounds, or even change the vocals on a song. Features like "Swap Sound" and "Replace Section" offer incredible flexibility for remixing, prototyping ideas, and refining your musical creations directly through the API.
Advanced Audio Separation
Unmix any song with our stem separation capabilities. The Basic Stem Separation can isolate vocals from instrumental tracks, while the Full Track Separation breaks a song down into its individual components like drums, bass, and melody. This is a game-changer for producers, DJs, and educators who want to analyze, sample, or remix existing audio with precision and ease.
