Introducing ACE-Step Prompt-to-Audio: Create Professional Music from Simple Text Prompts

The world of AI-powered music creation just got more accessible. WaveSpeedAI is excited to announce the availability of ACE-Step Prompt-to-Audio, a groundbreaking music generation model that transforms simple text descriptions into polished, full-length audio tracks. Whether you’re a content creator needing background music, a filmmaker seeking the perfect score, or a musician exploring new creative directions, ACE-Step delivers professional-quality results in seconds.

What is ACE-Step?

ACE-Step represents a new paradigm in AI music generation. Developed collaboratively by ACE Studio and StepFun, this 3.5 billion parameter model was designed from the ground up as a foundation model for music AI—not just another text-to-music tool, but a flexible architecture capable of understanding the nuances of musical composition.

What sets ACE-Step apart from competitors like Suno and Udio is its unique technical architecture. The model combines diffusion-based generation with Sana’s Deep Compression AutoEncoder (DCAE) and a lightweight linear transformer, enabling it to generate music that maintains coherent structure from beginning to end. According to research published on arXiv, ACE-Step achieves strong performance with scores of approximately 85 in Emotional Expression, 82 in Innovativeness, and 80 in Sound Quality in blind human evaluations.

The model supports 19 languages and understands a wide range of musical styles—from jazz and electronic to orchestral and lo-fi hip-hop. Simply describe what you want to hear, and ACE-Step interprets your keywords to blend rhythm, instruments, and mood into a cohesive composition.

Key Features

• Instant Prompt-to-Music Creation: Describe your vision in plain language—“A jazzy chillout track with a cozy vibe about rainy evenings in a quiet café”—and receive a complete, polished track
• Blazing Fast Generation: Synthesizes up to 4 minutes of music in just 20 seconds, achieving 15x faster performance than LLM-based alternatives
• Instrumental Mode: Toggle vocals on or off to create perfect background music for podcasts, videos, or film scoring
• Flexible Duration Control: Generate tracks from a few seconds to full 60-second compositions with precise control
• Reproducible Results: Set a seed value to recreate the same composition later, or randomize for unique variations
• Genre and Emotion Intelligence: The model understands nuanced descriptors like “melancholic,” “energetic,” “dark,” or “uplifting” and translates them into appropriate musical elements
• Automatic Genre Tags and Lyrics: Unlike basic text-to-music tools, ACE-Step auto-generates appropriate genre classifications and can create lyrics that align with your prompt

Real-World Use Cases

Content Creators and Social Media

Generate custom soundtracks for YouTube videos, TikToks, Instagram Reels, and podcasts without worrying about licensing fees or copyright strikes. Create unique audio that perfectly matches your content’s mood and pacing.

Film, Game, and Animation Scoring

Produce background themes, ambient layers, and emotional cues for visual media. The instrumental mode is particularly valuable for creating underscore that enhances rather than distracts from the visuals.

Music Production and Songwriting

Use ACE-Step to rapidly prototype melodies, explore chord progressions, or generate backing tracks for demos. It’s an invaluable tool for breaking through creative blocks and discovering new musical directions.

Marketing and Advertising

Create brand-aligned audio for commercials, product videos, and corporate presentations. Generate multiple variations quickly to find the perfect fit for your campaign.

Education and Experimentation

Teach musical structure, explore AI-based composition techniques, or simply experiment with turning abstract ideas into sound. The accessibility of the platform makes it an excellent learning tool.

Why WaveSpeedAI?

While ACE-Step is available as an open-source model under the Apache 2.0 license, running it locally requires significant GPU resources. WaveSpeedAI eliminates these barriers by offering:

• No Cold Starts: Your requests begin processing immediately—no waiting for infrastructure to spin up
• Optimized Performance: Our infrastructure is tuned for maximum throughput, delivering results faster than running the model yourself
• Simple REST API: Integrate music generation into your applications with just a few lines of code
• Affordable Pricing: At just $0.0002 per second of generated audio, creating a full minute of music costs only $0.012

The Future of AI Music Creation

ACE-Step represents what the research community calls “the Stable Diffusion moment for music”—an open, accessible foundation that enables new creative possibilities. According to MimicPC’s analysis, ACE-Step is considered the best AI music generator in ComfyUI for 2025, and its performance places it competitively among both open-source alternatives and commercial offerings.

The model’s architecture also enables advanced capabilities like voice cloning, lyric editing, and remixing that will unlock even more creative workflows as the technology matures.
