Virtual Acoustics (VA) v2022a - General concept, new features and use cases
Virtual Acoustics (VA) is a powerful framework for the auralization of virtual scenes and is developed at the Institute for Hearing Technology and Acoustics. It uses physics-based models for source, sound propagation and spatialization at the receiver and allows rendering scenes in real-time. Due to its modularity, VA can be applied to a variety of scenarios. However, this also is one of the main obstacles for new users when trying to get started.
With the new version v2022a, some major updates within the software but also the documentation are introduced making developers’ and users’ lives easier. In this presentation, the general concept behind VA’s audio processing is recapped before introducing the new features of v2022a. Finally, a variety of use cases - ranging from free-field over room acoustic to aircraft flyover scenarios - are discussed.
Presenting: Philipp Schäfer

Virtual source method - Aicraft flyover auralization considering atmospheric and urban propagation
มุมมอง 2972 ปีที่แล้ว
The virtual source method allows to interface between the Atmospheric Ray Tracing (ART) framework and the image edge model (IEM). ART simulates curved sound propagation paths considering the inhomogeneity of the atmosphere and wind. On the other hand, IEM assumes straight path propagation but considers interaction with surfaces and edges of buildings (reflection and diffraction). To interface b...

Performance of adaptive ray zooming approach during aircraft flyover
มุมมอง 4563 ปีที่แล้ว
Adaptive ray zooming is an efficient method to find eigenrays in a stratified, moving medium. The method is used in the Atmospheric Ray Tracing (ART) framework. This animation shows the method's performance with respect to accuracy and run-time based on a flyover scenario. The video is part of the open access publication: Atmospheric Ray Tracing: An efficient, open-source framework for finding ...

VA is awesome, I have managed to use it in my master thesis project in 2018
There's a test version for more current SketchUp versions (2020 - 2023) available, too. And sorry for the bad audio quality, I did only one take with the equipment I had in the office on that day and did not do any postprocessing. There are plans to generate a new version of the tutorial video.
Hi, which reverb did you use on this please?
mumbling, can't ear nothing
that a really nice plugin!!, were can I get access to it? thanks!
Hello blogger Can you send me the RAVEN software to use
Hi there. What does the LITE version of RAVEN can do? Does it work with Sketchup 2022?
The idea of the plugin is good! Nice plugin. Bad audio quality though of your presentation. It's to understand you in this recording. But hope you update the plugin to work in SU 2020 at least
Whenever I click on the auralization button it just opens an empty file and doesn't make an auralization. I have successfully generated the RIR so this isn't the problem. Can anyone help?
Where do you get the software please
Hi, congratulaions for the plugin. Where I can downlad it ?
Hi, this is a beautiful plugin. I tried to look online but I can't find any website where I can download it.
Send him an email :)
How was it?
