Creating a Doppler Effect by Using Automatic Mode as Insert Process

If you use Doppler in Automatic Mode as an insert effect, you must use automation to record the movement. 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.

  • You have opened the Video Player window.

  • You have added Doppler as insert plug-in.

  • 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.
  9. Activate Write Automation on the plug-in panel.
  10. Play back the complete passage.

    Automation data for the Doppler passage is written.

  11. Stop playback.

Result

Automation data for your Doppler passage is recorded.

To audition the created effect when using Doppler as insert effect, you must set the plug-in to Manual Mode first.

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.

  • We recommend to render the finalized Doppler passage into the audio before using the Render in Place function with Channel Settings. For more information about Render in Place, see the “Operation Manual”.
