GB SFX Studio is a lightweight, web-based audio tool designed to help developers create custom sound effects for GB Studio without the steep learning curve of classic tracker software or hex editing.

Design your sounds directly in your browser, export a perfectly formatted 32KB .sav file, and drop it straight into your GB Studio project.

Features:

• Visual Interface: Design Tone (Square) and Noise channel effects using intuitive sliders for frequency, volume, duty cycle, and speed.
• Instant Export: Generates a complete, hardware-accurate hammered.sav file instantly.
• GB Studio Ready: Files are perfectly mapped to the 32KB memory architecture required by GB Studio's internal audio driver.
• 60 SFX Slots: Create up to 60 unique sfx to export in a single file.  Name each slot and save project files to your device to come back to them later.
• 40 Presets: Includes 40 pre-made sound fx that you can load, edit and use in your own GB Studio projects.
  
• PWA Support: Install the app directly to your desktop or mobile device for offline, app-like access.
  

License & Support:

• Free to Use: The tool itself is completely free. Furthermore, any sounds or presets you create using this tool are 100% free to use in any of your personal or commercial projects.
• Support Development: While this tool is free, I am an independent developer. If you find GB SFX Studio useful, any tips are greatly appreciated and help support the development of future game dev tools!
