What are Doppler and Air?

Sound Particles proudly introduces the “Doppler + Air” plugins, two plugins that simulate the physical behavior of sound moving thru the air.

Available for Windows and MacOS.

About Doppler...

Doppler simulates the behavior of objects moving through air, providing audio with highly accurate characteristics of sounds passing-by. With control of all parameters that physically affect pitch, level and EQ in a real world situation, Doppler gives you the most natural sounding emulation for your work.

About Air...

Air simulates the natural dampening that happens to higher frequencies from sounds as they travel through air, providing perfectly simulated frequency responses to dialogue or effects that you want to sound naturally distant.

Some Features...


Highly Accurate Doppler

Accurate means Natural - because the brain knows what is natural and what is fake, you need the most accurate tools. Doppler plugin uses the same engine of Sound Particles, used in many Hollywood studios for creating the most natural sounding Doppler effects, but now available as a plugin.


Support for Immersive Audio

Simply select between different microphones, ranging from mono (omni, cardoid, figure-of-eight), stereo (MS, XY, ORTF, Blumlein, AB), 5.1, 7.1, 9.1 Dolby Atmos bed, or Ambisonics (up to 3rd order). The best Doppler for the best audio formats.


Perfect Image Sync

Specify the time where you want the peak of the Doppler, and all other parameters will adjust to get the perfect sync with the image.


Including Distance EQ

Besides volume and pitch, Doppler plugin also applies the perfect frequency response you would get from air dampening thru distance.

World Units

Do you prefer “meters” or “feet”? “Mph" or "km/h"? Full integration with Imperial and Metric units, for an easy and more welcoming workflow for everyone.

Doppler + Air

Instructions Manual always available

The instructions manual is always a button away.


Several Locations

Air already includes settings from different locations around the globe, from Antarctica to Death Valley, but you are always able to enter your one custom values.


Perfect result

Air is much more accurate than a simple low-pass filter, using exact frequency response values of air dampening.


Frequency Response

With Air, you can see the actual frequency response that is being applied to the sound.
