VISR- Versatile Interactive Scene Renderer Framework

The VISR framework is a collection of software for audio processing that forms the backbone for most of the technology created in S3A. In this extensible software framework, complex audio algorithms can be formed by interconnecting existing building blocks, termed components. 

It can be used either interactively in the Python language, in custom applications (for instance in written C++, or integrated into other applications, for instance as DAW plugins or Max/MSP externals. While the VISR provides several renderers and building blocks for spatial and object-based audio, it is nonetheless a generic audio processing framework that can be used in other applications, for example array processing or hearing aid prototypes. The Python integration makes the system accessible, and enables easy algorithm development and prototyping.

For Research:

  • Render object-based content through standalone renderer binaries.
  • Create new audio processing algorithms by combining and interconnecting existing building.
  • Run audio processing in real-time to loudspeakers or headphones (with optional binauralization).
  • Prototype new building blocks in Python.
  • Simulate algorithms and complex rendering schemes offline using the same code as for real-time rendering.

For Development​:

  • Use the VISR infrastructure to reduce the development effort for audio applications.
  • Create new components out of existing building blocks or implement new algorithms in C++.
  • Implement real-time rendering applications or embed VISR rendering components into other applications, for example DAW plugins or Max/MSP externals or custom GUIs.
  • Use the interactive Python integration for benchmarking and testing of audio algorithms.

For Creation/Production

  • Use through applications as DAW plugins in most cases.
