Software Distributions

  • AUDIENCE VR (distribution adapted for usage with 3D visualization in VR, based on PD patches and executable externals). Distribution in continuous development, oriented to integration to navigation appliations; employs Ambisonics as spatial codec.
  • OPEN AUDIENCE v.1.0 (open distribution in development, based on PD patches and executable externals). Distribution in colaborative development, open. Project incubated at FAPESP incubator .

Both distributions aim at packet enhancements, widening application areas, and developing new functionalities, such as: distributed auralization processing (distributing auralization tasks among computers), AUDIENCE distributions for easy installation, easy patch creation and edition, modules for stand-alone or command-line calls, binaural individual auralization, wave-field synthesis-based auralization, etc.).

All distributions possess blocks capable of simulating acoustic environments (acoustic simulators), of encoding sound field in space (spatial encoders), of decoding and generating individual channels/outputs for each loudspeaker used in the chosen configuration (spatial decoders). Builts are based on the PD visual programming platform (Pure Data).
