DTE (Double Tracking Effect) is a simulation of the famous artificial double tracking recording technique. The artificial double tracking effect was introduced in 60's to give a richer and wider sound.
The signal of a source tape player is routed to a second tape recorder-player.
This second tape records the source and plays it back adding both signals but not in a synchronous way.
The synchronization depends on the play head position of the second tape recorder-player.
By changing the head tape position (with LFO or manually) it changes the speed of the tape player generating alterations on the timbre and the pitch.
The DTE rack extension
There are 3 tape units :
- one tape player for the source
- two tape recorders-players with head position controls.
When the tape player head position is on 0 ms, it is synchronized with the source.
When the head position is negative then the signal is before the source signal.
When the head position is positive then signal is after the source signal.
The range is -40 ms to +40 ms.
A special option allows to take control on the second tape recorder-player via the controllers of the first one, making easy to control both.
The integrated Low Frequency Oscillators driving the head position have been especially adapted for their purpose.
The tape players have a drive parameter to control the amount of tape saturation.
The tape saturation has been precisely designed to simulate the rich sound of an analog tape player (signal driven compression, warm equalization and saturation).
The tape players have direct audio outputs. This allows to take advantage of the heads position (delay, pitch, timbre) in other effects.
With DTE, you can :
- make your sound warmer, wider, saturated.
- generate flanging or phasing effect by moving the head position near the 0 position and enabling the phase inversion.
- design a lot of creative effects by combining DTE with other effects with the direct audio outputs.
