Autolume

Autolume is a cross-platform tool for real-time visual performances using StyleGAN.

For detailed documentation and demos look at the Metacreation Lab Website.

Downloads

➡️ Download for Windows and macOS

Linux users need to run Autolume from sources following the development instructions.

Development instructions

uv is required for setting up the python environment (installation link)

Dependencies

Windows

• CUDA 12.8 (download link)
  • Minimum components: CUDA Development + CUDA Runtime
• Microsoft C++ Build Tools (download link)
  • Minimum components: Desktop development with C++
• FFmpeg: winget install Gyan.FFmpeg

Linux (Ubuntu 24+)

• CUDA (download link)
  • Minimum components: CUDA Development + CUDA Runtime
• FFmpeg and PortAudio: sudo apt install portaudio19-dev ffmpeg

macOS

• FFmpeg and PortAudio: brew install portaudio ffmpeg
• Command Line Tools for Xcode: xcode-select --install

Initial setup

Create the Python environment:

uv sync

Running the program

Start the program

uv run main.py

Create a release

Run the cross-platform release script on the OS you want to build for (PyInstaller cannot cross-compile — a Windows build must run on Windows, etc.):

uv run release.py

ffmpeg/ffprobe are downloaded and bundled into the release automatically via ffmpeg-downloader.

• Windows / Linux: output is the dist/Autolume/ folder.
• macOS: output is dist/Autolume.app, code-signed automatically — see macOS signing and notarization.

Pass --package to additionally produce a distributable: an .AppImage on Linux, a .dmg on macOS, or an Inno Setup installer plus a portable .tar.xz archive on Windows (requires Inno Setup on the build machine, installable with winget install --id JRSoftware.InnoSetup.7 -e -s winget -i). Use --package-only to package an existing dist/ output without rebuilding.

macOS signing and notarization

Gatekeeper only opens a downloaded app without friction when it is both signed with a Developer ID and notarized by Apple (an automated malware scan of the uploaded file — this applies to all distribution outside the App Store, GitHub releases included). The release script handles both, after a one-time setup.

One-time setup

1. Signing certificate: install a Developer ID Application certificate and its private key in your login keychain. Verify it is visible with:

   security find-identity -v -p codesigning

2. Notarization credentials: ask a team admin for an App Store Connect API key with the Developer role (App Store Connect → Users and Access → Integrations → Team Keys). You need three values from that page: the .p8 key file, the Key ID, and the Issuer ID. Store them under the autolume-notary keychain profile:

   xcrun notarytool store-credentials autolume-notary \
     --key AuthKey_XXXXXX.p8 --key-id <key-id> --issuer-id <issuer-id>

Release flow

uv run release.py --package --notarize

• The build signs Autolume.app (hardened runtime + entitlements.plist) with the Developer ID certificate found in the keychain. If there is none, the script warns and falls back to an ad-hoc signature; the app then still runs locally, but downloads are blocked by Gatekeeper.
• --package wraps the app into a .dmg and signs it.
• --notarize submits the .dmg to Apple (usually takes a few minutes) and staples the resulting ticket, so users can open the app with a plain double-click. It can also be run on its own against an already-built .dmg — notarizing after the fact also unblocks copies that were published or downloaded earlier, since Gatekeeper checks Apple's servers online.

Building documentation

uv run zensical build
