Try WaveSpeedAI Ace Step for FREEIntroducing ACE-Step: Revolutionary AI Music Generation Now Available on WaveSpeedAI
The landscape of AI-powered music creation has just taken a monumental leap forward. We’re thrilled to announce that ACE-Step, the groundbreaking open-source music generation foundation model, is now available on WaveSpeedAI. This isn’t just another text-to-audio tool—it’s what researchers are calling “the Stable Diffusion moment for music.”
What is ACE-Step?
ACE-Step (A Step Towards Music Generation Foundation Model) represents a fundamental shift in how AI approaches music creation. Developed collaboratively by ACE Studio and StepFun, this model doesn’t simply generate audio clips—it composes complete songs with vocals, instrumentals, and synchronized lyrics from nothing more than a text description and a few style tags.
What sets ACE-Step apart from existing solutions is its architectural innovation. By combining diffusion-based generation with Sana’s Deep Compression AutoEncoder (DCAE) and a lightweight Linear Transformer, ACE-Step achieves something previously thought impossible: blazing-fast generation speeds without sacrificing musical coherence or audio fidelity.
According to benchmark evaluations, ACE-Step achieves strong performance with scores of approximately 85 in Emotional Expression, 82 in Innovativeness, and 80 in Sound Quality—placing it competitively among both open-source and commercial alternatives in the rapidly evolving AI music generation space.
Key Features
Lightning-Fast Generation
ACE-Step synthesizes up to 4 minutes of complete music in just 20 seconds on an A100 GPU—that’s 15 times faster than LLM-based alternatives. The real-time factor (RTF) benchmarks are remarkable:
- NVIDIA RTX 4090: 34.48× real-time (1.74 seconds for 1 minute of audio)
- NVIDIA A100: 27.27× real-time (2.20 seconds per minute)
- NVIDIA RTX 3090: 12.76× real-time (4.70 seconds per minute)
Complete Song Creation
Unlike tools that generate short clips requiring manual stitching, ACE-Step produces coherent, structured compositions up to 4 minutes long—complete with verses, choruses, bridges, and synchronized vocals.
Advanced Control Mechanisms
- Voice Cloning: Replicate specific vocal styles for personalized tracks
- Lyric Editing: Modify lyrics while preserving the underlying melody and accompaniment
- Remixing: Transform existing musical ideas through the same intuitive interface
- Track Generation: Create lyric-to-vocal conversions or transform singing into accompaniment
Multilingual Support
ACE-Step supports 19 languages with optimal performance in English, Chinese, Russian, Spanish, Japanese, German, French, Portuguese, Italian, and Korean—opening creative possibilities for global audiences.
Fine-Grained Style Control
Simply enter style tags like “lofi, hiphop, chill” or “epic orchestral, cinematic, dramatic” to guide genre, tempo, mood, and energy with precision.
