Current methods face inherent trade-offs between generation speed, musical coherence, and controllability. For instance, LLM-based models (e.g., Yue, SongGen) excel at lyric alignment but suffer from slow inference and structural artifacts. Diffusion models (e.g., DiffRhythm), on the other hand, enable faster synthesis but often lack long-range structural coherence.<a target="_blank" rel="ugc" href="https://github.com/ace-step/ACE-Step">‌ACEStep‌</a> 是一款由 ACE Studio 与 StepFun 联合开发的音乐生成模型，被誉为“音乐界的Stable Diffusion”。该模型以其惊人的生成速度和多样化功能引发行业热议，能够在短短20秒内生成一首长达4分钟的完整音乐作品，效率比主流模型快15倍以上‌ACE-Step bridges this gap by integrating diffusion-based generation with Sana’s Deep Compression AutoEncoder (DCAE) and a lightweight linear transformer. It further leverages MERT and m-hubert to align semantic representations (REPA) during training, enabling rapid convergence. As a result, our model synthesizes up to 4 minutes of music in just 20 seconds on an A100 GPU—15× faster than LLM-based baselines—while achieving superior musical coherence and lyric alignment across melody, harmony, and rhythm metrics. Moreover, ACE-Step preserves fine-grained acoustic details, enabling advanced control mechanisms such as voice cloning, lyric editing, remixing, and track generation (e.g., lyric2vocal, singing2accompaniment).<a target="_blank" rel="ugc" href="https://private-user-images.githubusercontent.com/30956809/441739923-0a13d90a-9086-47ee-abab-976bad20fa7c.png?jwt=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.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.APSO1yodIjmcoLizCyIsvogv9cOQvokgD0prFJ4Dkis"><img src="https://private-user-images.githubusercontent.com/30956809/441739923-0a13d90a-9086-47ee-abab-976bad20fa7c.png?jwt=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.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.APSO1yodIjmcoLizCyIsvogv9cOQvokgD0prFJ4Dkis" alt="图片" /></a>技术特点和应用场景ACEStep 基于 DiT（Diffusion Transformer）架构，采用轻量化设计，支持在消费级GPU上运行，显著降低了硬件门槛。该模型支持19种语言，包括英语、中文、日语、西班牙语等，为全球音乐创作者提供了广泛的适用性‌ACEStep的核心功能包括：‌歌词驱动创作‌：输入歌词，模型自动生成旋律并演唱完整歌曲。‌风格化编曲‌：根据指定的风格标签（如说唱、电子乐、流行等），自动生成伴奏和配器。‌精准修改‌：支持对歌曲某段歌词进行修改，而不影响原有旋律的连贯性。‌多样化生成‌：能够生成带风格的说唱、电子乐、人声或复杂配器，满足不同音乐场景需求‌<h3 id="baseline-quality-g8yj91kdk">🎯 Baseline Quality</h3>🌈 Diverse Styles &amp; Genres<ul><li>🎸 Supports all mainstream music styles with various description formats including short tags, descriptive text, or use-case scenarios</li><li>🎷 Capable of generating music across different genres with appropriate instrumentation and style</li></ul>🌍 Multiple Languages<ul><li>🗣️ Supports 19 languages with top 10 well-performing languages including:<ul><li>🇺🇸 English, 🇨🇳 Chinese, 🇷🇺 Russian, 🇪🇸 Spanish, 🇯🇵 Japanese, 🇩🇪 German, 🇫🇷 French, 🇵🇹 Portuguese, 🇮🇹 Italian, 🇰🇷 Korean</li></ul></li><li>⚠️ Due to data imbalance, less common languages may underperform</li></ul>🎻 Instrumental Styles<ul><li>🎹 Supports various instrumental music generation across different genres and styles</li><li>🎺 Capable of producing realistic instrumental tracks with appropriate timbre and expression for each instrument</li><li>🎼 Can generate complex arrangements with multiple instruments while maintaining musical coherence</li></ul>🎤 Vocal Techniques<ul><li>🎙️ Capable of rendering various vocal styles and techniques with good quality</li><li>🗣️ Supports different vocal expressions including various singing techniques and styles</li></ul>Rather than building yet another end-to-end text-to-music pipeline, our vision is to establish a foundation model for music AI: a fast, general-purpose, efficient yet flexible architecture that makes it easy to train sub-tasks on top of it.
