SW Room is a room reverb you can see: a source and a pair of microphones in a rectangular room. Move the walls and the microphones, and set the decay on its own.
This installs SW Room 1.0.0 for macOS 11 or later (Apple silicon and Intel):
SW Room.component to /Library/Audio/Plug-Ins/Components/SW Room.vst3 to /Library/Audio/Plug-Ins/VST3/Both formats are selected by default. An administrator password is required (system Library install location).
Before installing: quit your DAW. This package does not install or remove any other Signalwork plugin. Your preferences and licenses are preserved.
Older copies: after the new system-Library bundle is confirmed, an older SW Room of the same format in your user Library is moved to ~/Library/Application Support/Signalwork/rollback/ so it cannot shadow the system install. Nothing is deleted, and other plugins are never touched.
