阶跃星辰（StepFun）与 ACE Studio 发布 StepAudio 3 Music，这是阶跃星辰首个音乐生成基础模型，可从提示词和歌词生成完整歌曲。模型支持歌曲生成、纯音乐生成、音乐翻唱和人声转歌曲编排四种工作流，基于 ABC-COT 先规划曲式结构再合成，用户可改写提示词、编辑 ABC 记谱迭代调整，交互式演示已上线，ABC-COT API 即将推出。
StepFun and ACE Studio present StepAudio 3 Music, StepFun’s first music generation foundation model — built to turn a prompt and lyrics into a complete song.
Describe the sound you want:
• Genre, mood and vocal character
• Instruments, key and BPM
• Song structure and arrangement
Four workflows in one model:
🎤 Song generation
🎹 Instrumental generation
🔁 Music cover
🎙️ Vocal-to-song arrangement
Powered by ABC-COT, it plans musical structure and arrangement before synthesis. Generate a version, rewrite the prompt, edit the ABC notation, and iterate toward the sound in your head.
(ABC-COT API coming soon)
