Learn about applying Graphic Phase Shifter effect while editing in Audition.

The Stereo Imagery > Graphic Phase Shifter effect lets you adjust the phase of a waveform by adding control points to a graph.


Right-click points to access the Edit Point dialog box for precise, numerical control.

Phase shift graph

The horizontal ruler (x‑axis) measures frequency, while the vertical ruler (y‑axis) displays the degree of phase to shift, where zero is no phase shift. You can create simulated stereo by creating a zigzag pattern that gets more extreme at the high end on one channel.

Frequency Scale

Sets the values of the horizontal ruler (x‑axis) on a linear or logarithmic scale. Select Logarithmic to work at finer detail in the lower frequencies. (The logarithmic scale better reflects the frequency-emphasis of human hearing.) Select Linear to work at finer detail in the higher frequencies.


Sets the values of the vertical ruler (y‑axis) on a 360° or 180° scale.


Specifies the channel(s) to apply the phase shift to.


Process a single channel for the best results. If you apply identical phase shift to two stereo channels, the resulting file sounds exactly the same.

FFT Size

Specifies the Fast Fourier Transform size. Higher sizes create more precise results, but they take longer to process.
