Important changes


In 2023, the network communication between the VAServer and bindings underwent a major rework. As a result, there is no backwards compatibility to previous versions regarding the network communication. For example, controlling a VAServer of version v2023a with VAMatlab v2022a will not work.


In 2022, we introduced major changes in our build system. This allows us to use compilers newer than VC12 for all VA components. Generally, this lead to the following changes for newly deployed VA versions:

  • VAPython is now part of the VA_full build. The VA_bindings build is not shipped anymore.
  • VAPython is now included as wheels which makes installing much easier
  • We stopped developing the Redstart GUI and removed it from the packages




  • Now default paths (data and conf) are automatically added and do not need to be added to VACore.ini
  • The data folder now contains additional signals and directivities (e.g. for car pass-by and aircraft noise).


  • Now allows real-time auralization with inhomogeneous medium
  • Data histories for simulation results can now be configured to select interpolation method


  • Significant rework/extension of examples: Now most examples
    • ...come with a VACore.ini file
    • ...automatically start the VAServer for you
    • ...have detailed comments and cross-references


  • General
    • Fixed several bugs regarding the calculation of air attenuation: in some cases attenuation values could be significantly off
    • The lock_scene() and unlock_scene() did not work anymore due to change of VANet in v2023a, which is fixed now
  • VAServer
    • Now properly cleans up the core if closing the window
    • run_VAServer_recording.bat now works again: fixed start argument for remote control

Network communication rework (VANet)

  • Now based on gRPC
  • No backwards compatibility (e.g. VAMatlab v2022a won't work with VAServer v2023a)


  • New thread-safe logging system with improved formatting and file log
  • VAServer: Improved command line interface, with backwards compatibility
  • Now all coord transformations are unified throughout VAServer and bindings

Rendering (VACore)

  • Soundpath-based renderers now use one SIMO VDL per source instead of one VDL per sound path
  • AirTrafficNoiseRenderer now allows scheduling of ART simulations for real-time purposes
  • New OutdoorNoiseRenderer which allows binaural, ambisonics and VBAP signals (replaces BinauralOutdoorNoiseRenderer)


  • New setup function (VAMatlab_setup()) adding relevant folders to Matlab path
  • Now has a set of convenience classes to render dynamic scenarios
  • Supports multiple tracked sources


  • Now comes with a single, version independent wheel for Python >= 3.8
  • Fixed a bunch of bugs leading to increased robustness


  • Fixed a bug where third-octave band magnitude spectra were not parsed correctly when calling SetParameters()
  • Fixed a crash that could occur when using the Burg algorithm for IIR filtering
  • See VAPython

VACore - Rendering system rework

  • Now distinguishs between FIR-based and sound-path-based renderers
  • Sound-path-based renderers are not restricted to binaural output anymore but can choose from binaural / Ambisonics / VBAP
  • e.g. FreeField renderer replaces AmbisonicsFreeField and VBAPFreeField


  • Tracking now works with AR-Tracking (in addition to OptiTrack)


  • Is now installed using wheels
  • Now shipped with version 3.8 to 3.10


  • Undesired default receiver position ([0 0 0]) removed
  • Fixed performance issues of Windows timer used in VAMatlab
  • Fixed CTC crash that could occur if utilized HRTF did not cover a full sphere
  • Fixed bug in ITASimulationScheduler where mainly a single source-receiver pair was simulated disregarding other sound sources


  • Now a receiver becomes active as soon as it has a valid position. The set_active_listener function should not be used anymore was removed from all bindings.

VAServer / VACore

  • Now comes with VACore.recording.ini file for offline rendering. Use run_VAServer_recording.bat to start VAServer with this configuration.

VACore - AirtrafficNoiseRenderer

  • Now can switch between homogeneous and inhomogeneous medium
  • Homogeneous medium: straight sound paths calculated within VA
  • Inhomogeneous medium: curved sound paths simulated with Atmospheric Ray Tracing framework


  • Previously only working for Python 3.6, now only works with Python 3.7 and higher
  • Now shipped with version 3.7 to 3.9

Linux, Mac OSX and other

From the very beginning, Virtual Acoustics has been developed and used under Windows platforms. If you do not have a Windows system, you can still use VA. Unfortunately, we are not experienced in building binary packages for other platforms than Windows, hence you will have to build it from the source code. However, we can't guarantee smooth performance on those systems. For more information, read the developer section.

A common alternative way is to run the VA server application on a dedicated remote Windows PC with a proper ASIO interface, and control it from any other platform. This way, you can use the Windows download package and you only have to build the remote control part of VA (the C++ interface libraries and/or bindings). You will require no further third-party libraries except for the binding interface you choose (usually Matlab or Python). You can also run a Jupyter notebook along with VA on the Windows machine and remotely control everything using a web browser on any mobile device connected to the same network.

Some hints on VA packages

VA is always in development and we constantly add new features or components. Therefore, we chose the version identifier to reflect the release year and added an ascending alphabetic character, like v2018a. This makes it easier to determine the release time, just like in Matlab and other applications.

We cannot guarantee compatibility among VA versions! The reason is, that we still update the interface for new powerful features. This is unfortunate, but can not be achieved with the resources we can afford. If you are interested in new features, you will have to pay the price and update everything, including the bindings you use.

We adopt naming conventions for platforms and compiler versions from ViSTA VR Toolkit. This way, one can easily extract the target platform, such as win32-x64 for a Windows operating system using a mixed 32 bit and 64 bit environment, or vc12 to indicate that the binary package was built using the Microsoft Visual C++ Compiler Version 12. If you are missing redistributable libraries you can identify the required Microsoft installer by this suffix.

The build environment of VA provides configuration of the underlying components. This may or may not result in a binary package that links against GNU GPL licensed libraries. For this reason, VA is either licenses under the favored Apache License, Version 2.0 or under the GNU General Public License, as required by the copyleft nature.
