What Doppler + Air does
The Doppler module models the pitch shift and volume change of a moving object, and it applies the distance equalization that accompanies the movement, so the frequency response follows the real-world situation rather than a generic filter. Every parameter physically affects pitch, level and EQ, and the developer describes the result as natural because the ear recognizes the movement it expects.
Key features
- Highly accurate Doppler. The Doppler effect is calculated from the physical movement, so pitch, level and EQ change together as the object passes.
- Immersive microphone selection. Different microphone types, from mono omni to immersive setups, can be chosen to capture the moving source.
- Peak timing. A chosen time can be set as the point of peak Doppler, and the other parameters are aligned to that moment.
- Distance EQ. Besides volume and pitch, the plugin applies a distance-dependent frequency response.
- World units. Distances and speeds can be entered in meters, feet, mph or km/h.
- Control surface support. Parameters can be edited from control surfaces such as the AVID S6.
Compatibility
The bundle is listed for VST3, VST2, AU and AAX on Windows 7 and macOS 10.9 or later, with native Apple Silicon support and 4 GB of RAM.
