Creating a Doppler Effect by Using Automatic Mode as Offline Process

If you want to create a Doppler effect as offline process, you must use the plug-in in Automatic mode. In this mode, the sound source is linked to the project cursor. This allows you to create a passage with a Doppler effect by setting specific positions.

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, and the audio event on the track is selected.

  • If the audio track contains more than one event between start and end position of the movement, you have bounced these events to one continuous event.

  • You have opened the Video Player window.

  • In the Direct Offline Processing window, you have activated Auto Apply.

  • You have added the Doppler plug-in as offline process.

  • On the plug-in panel, you have activated Automatic mode.

Procedure

  1. Optional: Click Panning Direction to set the direction in which the sound source moves.
  2. On the Transport Panel, start playback.
  3. At the time position where you want the movement of the sound source to start, click Set Start Position.
  4. Optional: When the pitch change is supposed to begin, click Set Transition Start Position.

    If this step is skipped, the transition start position is set to a default value.

  5. At the time position where you want the movement of the sound source to pass, click Set Listener Position.
  6. At the time position where you want the movement of the sound source to end, click Set End Position.
  7. To fine-tune the start, transition start, listener, and end positions, move the mouse over the corresponding timecode and move the mouse wheel.
  8. Click Locate to set the left and the right locator to the defined start and end position, and to move the project cursor to the start position.

Result

The effect is rendered to the audio of your Doppler passage.

To audition the created effect, play back the range between left and right locator.

After Completing This Task

In the Parameters and the Panorama section, adjust the parameter settings until the effect meets your expectations. These parameter changes are instantly rendered into the audio.
