ACE-Step — Text-to-Audio
ACE-Step Text-to-Audio is a next-generation AI music generation model that composes complete songs — including vocals, instrumentals, and lyrics — directly from text descriptions. Produce professional-quality music up to 4 minutes long from simple style tags and optional lyrics.
Why It Stands Out
- Text-to-music generation: Transform style tags into coherent music tracks with melody, rhythm, and vocals.
- Style tag control: Enter multiple tags to guide genre, tempo, and energy.
- Vocal and lyric creation: Generates original vocals and synchronized lyrics that fit your prompt's tone.
- Fine-grained acoustic fidelity: Maintains dynamic balance, spatial quality, and instrument clarity.
- Flexible duration: Adjustable from a few seconds to 4 minutes (240 seconds).
- Reproducibility: Use the seed parameter to recreate exact results.
