Creating a Doppler Effect by Using Manual Mode

In Manual mode, you can move the sound source with a slider. For this to work, you must load the plug-in as an insert effect and use automation to record the movement.

Prerequisite

  • Your project contains a video track and an audio track of a sound source that passes in front of the listener, for example, a car that passes by.

  • You have opened the Video Player window.

  • You have added Doppler as insert plug-in.

  • On the plug-in panel, you have activated Manual Mode.

  • You have activated Write Automation on the plug-in panel.

Procedure

  1. Set the Object Position slider to the position where the movement of the sound source in the video starts.
  2. Optional: Click Panning Direction to set the direction in which the sound source moves.
  3. On the Transport Panel, start playback.
  4. On the plug-in panel, move the Object Position slider corresponding to the movement of the sound source.

    Automation data for the Doppler passage is written.

  5. Stop playback.

Result

Automation data for your Doppler passage is recorded. To audition the created effect, play back the passage with automation.

Note

Modifying existing automation data for Doppler parameters can be troublesome. Therefore, we recommend to start from scratch if the automation pass does not meet your expectations.

After Completing This Task

  • Use automation to adjust the controls in the Parameters and the Panorama section, until the effect meets your expectations.
