The VISR Production Suite is the first open-source set of DAW plugins for producing and reproducing object-based audio. The fundamental elements of an object-based production are:
  • Objects: audio objects are audio signals with associated metadata.
    The metadata of all the objects together form the
  • Scene: a way to represent the metadata of the set of objects, which is neutral in regard to the output audio format and system. Those information are sent to the
  • Renderer: a component that uses the scene metadata to mix the signals of the objects in order to generate the output audio signals for different types of devices (Loudspeakers, Headphones, …) and layouts ( stereo, binaural, 5.1, 7.1, 22.1, …).

We provide these elements within the VISR Plugin Suite under the form of:

Object Editor

Put this plugin on each track to transform your tracks into audio objects

Scene Master

Place this plugin in your DAW session to manipulate the whole object-based audio scene

Rendering plugins

Use these plugins to reproduce the scene on various loudspeaker layouts, sound bars, or headphones

What you can do with the VISR Production Suite:

  • Create an object-based session
  • Spatialise and control your audio objects
  • Easy binaural content creation with different sets of HRIR and BRIRs in SOFA format
  • Head tracking and head orientation compensation capabilities, suitable for VR
  • Create loudspeaker layout agnostic spatial audio content and render it for different loudspeaker systems with just one click
  • Exploit JUCE framework and the VISR, a modular open-source framework for audio processing
