tubePlug free routing by t-u-b-e

tubePlug is a free routing VST, Audio Unit plugin developed by t-u-b-e. Compatible OS(s): Windows, macOS.

tubePlug is a network audio plug-in that can connect multiple tubePlug users via the Internet and allows high quality multi-channel audio exchange between them.

It has three faces: it can be a receiver, sender or server. To start a music network session one server should be provided by one member of the session. In t-u-b-e hosted “real” performances the server is provided by the venue.

After the server is running, senders and receivers can log in to the server. Senders can send stereo high quality audio streams and receivers can choose between the provided streams and receive them. Additionally the server provides an audio sum that can be chosen by the receiver too. This sum is the audio mix (pure same level addition) of all senders.

tubePlug runs as a VST / Audio Unit plug-in on Mac OS X 10.3.9 or higher (Universal Binary) and as a VST plug-in on Windows 9x / ME / XP.

tubePlug is a project of the t-u-b-e gallery for radiophonic art installations and audio performances City of Munich – Cultural Office in collaboration with büro Munich.

NOTE: tubePlug is freeware only for non commercial projects.
