Proscenion is a simple graphical program that allow one to graphically put Jack audio sources on a scene (stage) and get a stereo mixdown from the capture item, based on the position of each source to the capture item. The stereo effect, both in amplitude and phase, is then send to a Jack output. It's like a multitrack to stereo downmixer, but with a more realistic stereo.
This software is mostly useful for stereo masterisation of multi-track audio sources, either live (with microphones) or afterwards (with multi-track audio file players). The capture model is a virtual couple of omnidirecitonnal mircophones separated by 20cm from each other. This is a simple model to simulate a human dummy head stereo capture.
