Text-to-audio tools such as Suno generate music, and research models like Meta’s MusicGen and AudioGen generate music and sound effects from text prompts. Before using output in a game, check each tool’s terms of service – some restrict competing uses or AI training reuse.
At a glance
| Fact | Value | Source |
|---|---|---|
| MusicGen trained on licensed music | Meta AudioCraft | arxiv.org |
| AudioGen trained on public sound effects | text-to-audio | arxiv.org |
| Suno output cannot power competing AI models | prohibited | suno.com |
For browser games, the practical AI options fall into two groups: text-to-music services like Suno, and research-grade text-to-audio models such as Meta’s MusicGen and AudioGen from the AudioCraft project, which a paper on generating game audio from user-generated content describes as generating “music from text-based user inputs” (MusicGen) and audio from text-based prompts trained on public sound effects (AudioGen), see arxiv.org/html/2404.17018. Once built, tools like Playgama MCP let your coding agent publish a sandbox playtest link.
What to check before shipping AI-generated audio
- Read the tool’s terms, not marketing pages. Suno’s terms of service state you may not use its output “to create a competing music-generation product or service,” and forbid using output to “power, enable or train other artificial intelligence and machine learning models” – relevant if you resell or redistribute generated tracks (suno.com/terms).
- Licensed SFX libraries are a safer alternative for commercial sound effects. Sonniss states that sound effects bought through its bundle license can be used commercially without attribution, but explicitly denies any right to use those files “for training artificial intelligence technologies” (sonniss.com/gdc-bundle-license).
- File size and format matter for browser games. Compressed formats (OGG/MP3) loaded via Web Audio keep load times down; test AI-generated tracks the same way you’d test any asset for first-load size on a portal iframe.
- If you publish to Steam later, its content survey asks you to disclose “pre-generated” AI content that ships with the game (partner.steamgames.com) – not relevant to browser-only releases but worth knowing if you port.
Terms change; always check the tool’s current page before shipping.

Related questions
Can I use AI-generated music commercially in a browser game?
Depends on the tool’s terms. Check the license before shipping – some services restrict competing commercial uses or reuse of output to train other models.
Are licensed sound effect libraries safer than AI generators?
For clear commercial rights, yes – libraries like Sonniss grant explicit commercial-use licenses, though they explicitly forbid using the files to train AI models.
Do AI audio tools work well with Web Audio in a browser game?
Yes, once exported to a compressed format like OGG or MP3, AI-generated audio loads and plays through Web Audio the same as any other audio asset.
