# Doubler

Doubler window

The Doubler emulates "Artificial Double Tracking" as it was done with tape recorders in the sixties. It is typically used on vocal tracks to make the vocals sound a bit "fatter". The Doubler effect can also model sixties-style phasing/flanging effects, since these were created with tape recorders in a similar setup.

The Doubler mixes a delayed copy of the signal with the original signal. The delay time is modulated with a randomly varying triangle wave. This results in slight timing and pitch differences between the two voices.

The Delay knob sets the average delay time. Low delay values result in a "fatter" voice rather than two separate voices. High delay values result in two distinct voices. The Speed and Depth knobs control the modulation.

The Mix knob sets the dry/wet ratio (0% being dry only, 100% being wet only). Lower values result in a subtle thickening of the sound without noticeable doubling.

The Phase Invert button inverts the phase of the delayed signal. This results in a different sound, particularly at lower delay settings.

If you want to pan the two voices to different positions in the stereo image, you can use a Stereo Effect. You can then use the Stereo Effect's Pan controls. The Stereo Effect has a Stereo Doubler preset.
