Stereo Imager

Stereo Imager window

The Stereo Imager effect can change the width of the stereo image. It works with both stereo and mono input signals.

The Width knob controls the stereo image width. The Reverse button swaps the left and right channels.

Mono input signals are converted to stereo using a filter. Two filter types are available:

Shelve: Low frequencies are directed to the left channel, and high frequencies are directed to the right channel. The Color knob controls the crossover frequency.
Comb: A delayed signal is added to the left channel and subtracted from the right channel. The Color knob controls the spacing between the notches of the comb filter.

Both mono-to-stereo algorithms are mono-compatible: when the stereo outputs are summed, the resulting signal is identical to the original mono input.

Tip: Alternatively, you can pan the track to one side and its reverb to the opposite side. You can use an Effect Return section for the reverb, or you can use a Stereo Effect in the track. The Stereo Effect has presets for this.
