The Effects > Special > Doppler Shifter effect creates the increase and decrease in pitch we notice when an object approaches and then passes us, such as when a police car passes with its siren on. When the car comes toward you, the sound reaches your ears as a higher frequency because each sound wave is compressed by the car moving forward. The opposite happens as the car passes by; the waves are stretched out, resulting in a lower‑pitched sound.
Unlike many graphs in Adobe Audition effects, the Doppler Shifter graph is noninteractive: You can’t directly manipulate the graph. Instead, the graph changes as you adjust the effect’s parameters.
Path Type
Defines which path the sound source appears to take. Depending on the path type, a different set of options is available.
Controls
Straight line options
Circular options
Straight Line options:
- Starting Distance Away sets the virtual starting point (in meters) of the effect.
- Velocity defines the virtual speed (in meters per second) at which the effect moves.
- Coming From sets the virtual direction (in degrees) from where the effect appears to come.
- Passes In Front By specifies how far (in meters) the effect seems to pass in front of the listener.
- Passes On Right By specifies how far (in meters) the effect seems to pass to the right of the listener.
Circular options:
- Radius sets the circular dimensions (in meters) of the effect.
- Velocity defines the virtual speed (in meters per second) at which the effect moves.
- Starting Angle sets the beginning virtual angle (in degrees) of the effect.
- Center In Front By specifies how far (in meters) the sound source is from the front of the listener.
- Center On Right By specifies how far (in meters) the sound source is from the right of the listener.
Adjust Volume Based on Distance or Direction
Automatically adjusts the effect’s volume based on the values specified.
Quality Level
Provides six different levels of processing quality. Lower quality levels require less processing time, but higher quality levels generally produce better sounding results.
