Tonsturm’s new Traveler is a high-spec processor that recreates the Doppler effect in plug-in form.

Using Traveler’s graphical path editor, you can determine a sound’s virtual movement, and with Duration, Length and Speed parameters, you can customize exactly how it moves in seconds, frames, miles, meters, beats and other units of measurement.


As well as live processing, Traveler also has a fully-functioning granular sampler, letting you change the Pitch, Size, Density, Pan, Position and Jitter of sample playback.

On the right-hand side, you find physical propagation parameters (Air absorption, Attenuation, Doppler Pitch, Damping…) and five full effects (Tremolo, Delay, Distortion, EQ and Compression). Besides that control over the sonic soundscape, Traveler also has four custom shapeable LFOs to assign to the sampler and effects controls too.


$179 introductory price until August 1, 2018 ($229 thereafter).
