Introducing the “Traveler” Doppler Plug-In
Web shop Tonsturm are well known for their outstanding sound effect libraries of challenging subjects. Lately they’ve branched out into creating plug-ins, too. Earlier this year, these inspired folks from Germany released a plug-in called Traveler.
We are very honoured to have contributed sound to this cool plug-in by our friends at Tonsturm. Today we will briefly share what the plug-in does, why it is cool, and how Airborne Sound played a part.
What is Traveler?
Traveler is a plug-in for Mac (macOS 10.9+, 64-bit) and Windows (7+, 64-bit) plug-in. It is available in VST, AU, and AAX plug-in formats licensed to an iLok 2+ dongle or bound to a single machine.
The price is $229, with a 7-day demo available. (As of this writing it’s actually 20% off until July 11th.)
Here is a link to Traveler.
What Can Traveler Do
Everyone knows the classic sound of a car horn passing: first it rises, the car passes, and then the tone drops as the car departs. This is known as the Doppler effect.
Traveler is a plug-in that recreates this – as well as other motion-based effects – with any sound.
How is Traveler Different?

What’s cool about Traveler is the control it provides when creating Doppler-like effects. A highlight is its two-dimensional grid. This allows control of path of the sound (the blue line), where the listener is (the pink dot), distance, and peak time. The result? Clicking and dragging on the grid allows effortless control of the motion of the sound and how it is heard.

The simple side-to-side Doppler path is displayed as default. Other paths are possible too. The plug-in offers 85 inspired movement presets, and you can create your own, too.

In addition, the motion can be modified by the movement, propagation, and LFO sections to allow altering:
- Duration, length, and speed.
- Doppler shift, attenuation, dampening, stereo positioning, air delay, and curve.
- LFO modulation.
This provides exceptionally fine adjustments of the sample’s timing and sound .

Want to go deeper? The plug-in also has a built-in granular sampler which allows changing the pitch, size, density, panorama, and position (forward, back, alternate).
Finally, Traveler also bakes in the ability to modify the sound with five customizable post effects: tremolo, delay, distortion, equalization, and compression.
In other words, the movement, propagation, and LFO sections control the sample’s stats and tonal characteristics, while the grid shapes its movement. The result is total control of a sample’s motion through virtual space. The granular sampler and post effects allow shaping the sound quality in creative ways.

Airborne Sound
Where does Airborne Sound come in? The plug-in is pre-stocked with 76 samples such as cars, planes, sci-fi vehicles, electricity and fire, UI elements, drums, and more. Each of these are available to be processed with Traveler, allowing for some cool out-of-the-box designed sound effect possibilities.

Airborne Sound is thrilled to have contributed one of our aircraft to the collection under the Fighter Jet preset. It’s actually an F-22 Raptor from our Jet Fighter Maneuvers sound library.
We were quite honoured to be asked to be included in what we feel is a cool and inspiring plug-in. But don’t take our word for it. Read some glowing reviews of the software here and here, and a forum thread on Gearslutz.
