Download on desktop

SFX Stacks is a desktop app for Windows and macOS. Open this page on your computer to download the installer.

You can still use this page on mobile to check requirements, pricing, and how the app works before installing it later.

What happens after install

  1. Add one or more local audio folders.
  2. SFX Stacks scans your files and builds its local library index.
  3. Search, browse, find similar sounds, preview waveforms, and export clips.
  4. Start a 14-day Pro trial inside the app later if you want to test Pro features.

Your original audio files stay where they are. Search and analysis are designed around local processing, and once the app and models are installed, the core library workflow does not need an internet connection.

System requirements

Windows

  • Windows 10 or Windows 11 (64-bit)
  • Initial install (app, model, and runtime packages) may use up to ~3 GB of disk space
  • Your sound library will require additional space wherever you store it
  • On Windows, the model and runtime files are downloaded to your system drive (usually C:)
  • Internet connection required for the initial model and runtime downloads

macOS

  • Apple Silicon (ARM64) Mac
  • Initial install (app, model, and runtime packages) may use up to ~3 GB of disk space

Offline use and updates

The core local library workflow can run without an internet connection after setup. Internet access may still be needed for the initial model/runtime downloads, updates, license refreshes, and support links.

SFX Stacks includes an automatic updater. You can also return to this page any time to download the latest installer manually.
