Pricing Structure

Open-Source Foundation

The Prompting System

Stable Audio’s greatest strength and weakness is its prompting system. Unlike template-based tools, it requires detailed text descriptions – but rewards expertise with incredible control.

Prompt Structure

The optimal format: [Style/Genre], [Mood], [Instruments], [Tempo/Energy], [Production notes], [Duration]

Example Prompts That Work

“Cinematic orchestral piece, epic and uplifting, full string section with brass accents, building from quiet to triumphant, Hans Zimmer style production, 120 seconds”

“Lo-fi hip hop beat, mellow and nostalgic, vinyl crackle, jazz piano samples, soft drums, 85 BPM, bedroom producer aesthetic, 90 seconds”

“Ambient soundscape, mysterious underwater atmosphere, synthesized whale calls, deep bass drones, reverb-heavy production, 180 seconds”

“Energetic EDM drop, festival main stage energy, saw wave leads, punchy kick drum, 128 BPM, professional mastering, 30 seconds”

“Acoustic folk song, intimate and melancholic, fingerpicked guitar, subtle strings, room recording ambiance, 150 seconds”

Advanced Prompting Tips

Reference Artists: Mention style influences for better results
Production Terms: Use audio engineering language (compression, EQ, reverb)
Structural Elements: Specify intro, buildup, drop, outro
Emotional Arc: Describe how the mood should evolve
Specific Instruments: Name exact instruments rather than general terms
Cultural References: Mention specific eras or scenes (80s synthwave, UK garage)

❓ Frequently Asked Questions

Can Stable Audio generate vocals?

Stable Audio 2.0 has experimental vocal capabilities, but they’re not as developed as Suno or Udio. It can generate basic vocalizations and humming but not full lyrics with clear words. For instrumental and atmospheric music, it excels.

Is Stable Audio really open-source?

The underlying research and architecture are open, following Stability AI’s philosophy. However, the web platform itself is a commercial product. Advanced users can potentially run models locally with technical expertise.

How does the duration control work?

Simply specify the exact duration in seconds in your prompt (e.g., “90 seconds” or “2 minutes 15 seconds”). The AI will generate music that matches your specified length within 1-2 seconds accuracy.

Can I use Stable Audio music commercially?

Yes, with the Pro plan ($11.99/month) you get full commercial rights to all generated content. You can use it in videos, games, apps, or even release it on streaming platforms.

What makes Stable Audio different from other AI music generators?

Three key differences: (1) Highest audio quality at 44.1kHz, (2) Precise duration control, and (3) Technical prompt control that allows for very specific outputs. It’s built for professionals who need exact specifications.

Is there an API available?

Not yet for the public, but Stability AI has announced API access is coming in Q4 2025. Enterprise customers can request early access. The API will likely follow their image generation API model.

Tips for Best Results

Prompting Mastery

Be Specific: Instead of “happy music,” try “uplifting major key progression, 120 BPM, acoustic guitar and strings”
Layer Your Prompts: Build complexity: start with genre, add mood, then instruments, then production style
Use Music Theory Terms: Mention keys, chord progressions, time signatures for more control
Reference Production Styles: “Mixed like a Marvel movie soundtrack” or “Lo-fi bedroom production”
Specify Structure: “30-second intro, building to climax at 60 seconds, fade out at 90 seconds”

Common Mistakes to Avoid

❌ Don’t:

Use vague terms like “good music” or “nice sound”
Expect perfect vocals – use Suno or Udio for that
Ignore the duration parameter – it’s Stable Audio’s superpower
Overlook sound design capabilities – it’s not just for music

Pro Workflow

🎯 Professional Tip: Generate multiple 30-second segments with slight variations, then combine them in your DAW for a dynamic full-length track. This gives you more control than generating one long piece.

Who Should Use Stable Audio?

✅ Perfect For

Video Editors: Need exact durations for scene scoring
Sound Designers: Want high-quality atmospheric and effect generation
Game Developers: Require loopable, high-quality background music
Music Producers: Looking for inspiration or layer elements
Technical Users: Comfortable with detailed prompting
Quality-Focused Creators: Need broadcast-quality audio

❌ Not Ideal For

Vocal Music Needs: Use Suno or Udio instead
Beginners: Steeper learning curve than competitors
Quick Generations: Requires thoughtful prompting
Template-Based Workflow: No presets or templates
Mobile Creation: Desktop-focused interface

Final Verdict

Stable Audio is the professional’s choice for AI music generation when quality and control matter most. Its 44.1kHz output quality and precise duration control set it apart from competitors, making it invaluable for video production, game development, and sound design.

At $11.99/month, it’s competitively priced considering the audio quality and commercial rights included. The free tier is generous enough for testing, though serious users will quickly need the Pro plan.

Bottom Line: If you need professional-quality instrumental music or sound design with precise control, Stable Audio is unmatched. It’s not the easiest AI music generator, but it might be the most powerful for professional applications. The 44.1kHz quality and duration control features alone justify its place in any serious creator’s toolkit.

Score Breakdown

For Video Professionals: 10/10 – Duration control is game-changing
For Sound Designers: 9/10 – Excellent for atmospheric and experimental audio
