Transfer

Doppler-Spatializer

Transfer is an audio positioner.

Other doppler plugins have confusing controls. Other spatialization plugins are unintuitive. Transfer handles both of these problems and packages them together, as it should be.

Taking advantage of ambisonic audio, Transfer handles the processes associated with both encoding and decoding of the sound internally, without having to mess around with a bunch of variables. Transfer keeps it dead simple; audio in, spatialized signal out.

Transfer also features two different control modes; a full spherical positioner, as well as an X/Y pad representing the left/right/front/back space around the listener.

  • Binaural-Ready

    Transfer models the human ear and filters incoming audio according to how your ears would perceive sound coming from a certain angle, allowing for an ultra-realistic spatial audio experience; without the high CPU usage!

  • Spread / Separation

    Transfer is able to perform "spreading" on the audio source to reduce the listener's ability to localize (or "point out") the sound for a more subtle spatial effect. Additionally, Transfer can separate the incoming audio to two points (left and right if the incoming audio is in stereo) and have both channels come in at separate angles, but retaining the same "distance".

  • Doppler-Enhanced

    Transfer simulates the doppler effect in a way that is a mathematically perfect representation of how it sounds in real life. Don't know what the doppler effect is? Listen to the demos below.

Extra Information

  • Toggleable doppler delay and air dampening filters
  • Binaural (HRTF) spatialization mode making use of a virtual speaker dodecahedron
  • Stereo spatialization mode, for more basic spatial positioning
  • Linear (constant speed) and smooth (filtered) movement modes
  • Source spread and separation controls, allowing for a "smeared" perceptual position spread over a larger area
  • Vectorized, resizable interface

  1. Spherical Panner. Controls the azimuth and elevation of the sound source. The orange dot is the "target" position (which you control via dragging), and the blue dot is the "source" position (which follows the target based on the smoothing settings). Double-click the spherical panner from "sphere" mode to "linear" mode (where the elevation is control linearly instead of in a realistic way).
  2. XY Pad. Controls the X and Y position of the sound source. Dots work the same as in the spherical panner.
  3. Y Slider. Controls the Y position of the target when in XY control mode.
  4. X Slider. Controls the X position of the target when in XY control mode.
  5. Doppler / Propagation Toggle. Toggles whether or not the sound source delays itself according to the speed of sound relative to the listener, and by extension, produces the doppler effect.
  6. Damping Toggle. Toggles if the amplitude will decrease and higher frequencies will roll off as the distance between the listener and sound source increases.
  7. Stereo / Binaural Switch. Switches between stereo panning and binaural spatialization. When off, binaural spatialization is active, and vice versa.
  8. Separation. Separates the sound source's left / right image to increase the "width" of the signal. More noticeable when in binaural spatialization mode.
  9. Azimuth. Controls the target point's azimuth value (in degrees). Disabled when in XY control mode. The knob wraps around itself.
  10. Control Mode Switch. Switches between the spherical and XY control systems.
  11. Elevation. Controls the target point's elevation value (in degrees). Disabled when in XY control mode.
  12. Spread. Increases the audio source's spread, and by extension, reduces the perceptual accuracy of the spatialized signal.
  13. Distance. Changes the maximum distance that the source can reach based on it's location.
  14. Smoothing / Speed. Changes either the smoothing rate, or the meters-per-second speed that the sound source moves at.
  15. Movement Mode Switch. Switches between the movement modes of the sound source.
  16. Dry / Wet Mix. Changes how much spatialization is applied to the output signal. Can sound strange when doppler is enabled (due to the changing delay)

  • Windows: VST3
  • OSX (Intel / ARM): VST3, AU

Should run fine on any recent operating system.
