Complete guide to using Suno
Transform any song into a new style - create jazz, acoustic, electronic, or any genre cover versions with AI-powered music recreation.
The Suno V5_5 Cover API enables you to upload any audio file and have AI recreate it in a completely different musical style. Whether you want to transform a rock song into a smooth jazz version, convert a pop track into an acoustic ballad, or create an EDM remix of a classical piece, the Cover API analyzes the original composition and regenerates it with new instrumentation, vocals, and arrangements while preserving the core melody and structure.
Describe the target style in natural language. The AI interprets your description and transforms the uploaded audio accordingly. Great for quick style transformations.
Specify exact style, title, and additional parameters for precise control over the cover output. Ideal for professional productions requiring specific musical attributes.
Convert songs between any genres - pop to jazz, rock to acoustic, classical to electronic. The AI understands hundreds of musical styles and their characteristic elements.
Generate new vocals in different genders and styles. Transform a male vocal track to female or vice versa, with natural-sounding AI vocals that match the new style.
Create pure instrumental covers or reimagine the instrumentation entirely. Replace guitars with strings, synthesizers with acoustic instruments, or any combination.
Control the balance between preservation and transformation with the audio weight parameter. Stay close to the original or create something entirely new.
Transform songs into new styles in just a few steps
Upload the song you want to cover. Supports MP3, WAV, OGG, M4A, and FLAC formats up to 50MB.
Describe the style you want or use custom mode to specify exact parameters. Be specific about instruments, mood, and tempo changes.
Fine-tune style weight, audio weight, and vocal preferences to achieve your desired result.
Submit the request and wait for the AI to analyze and recreate the song in the new style.
Retrieve the generated cover version. Each cover includes new instrumentation, arrangement, and optionally new vocals.
Follow these guidelines for optimal cover generation
Higher quality source files produce better covers. Avoid heavily compressed or low-bitrate audio for best results.
Instead of 'make it jazzy', describe specifics like 'smooth jazz with walking bass, piano comping, and brushed drums'.
Adjust audio weight based on how much of the original you want to preserve. Lower values allow more dramatic transformations.
Create official remixes and alternative versions of tracks for release on multiple platforms.
Generate custom cover versions tailored to specific audiences, events, or moods.
Create instrumental covers of songs for karaoke apps, practice tracks, and performance backing.
Demonstrate how songs sound in different genres for music theory and arrangement education.
Transform songs between any genres with high-quality AI that understands musical styles deeply.
Simple file upload API supporting all major audio formats. No complex preprocessing required.
Quick cover generation with typical completion times of 1-2 minutes for standard length songs.
