The 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.
Defines which path the sound source appears to take. Depending on the path type, a different set of options is available.
Straight Line options:
Adjust Volume Based on Distance or Direction
Automatically adjusts the effect’s volume based on the values specified.
Provides six different levels of processing quality. Lower quality levels require less processing time, but higher quality levels generally produce better sounding results.
