Erik Sigth

Frekvens is a frequency shifter and delay effect. Unlike a pitch shifter all frequencies are shifted linearly and then fed back into itself using the stereo delay unit. The frequency shifting is achieved with single sideband modulation using a hilbert transform and an infinite impulse response filter for fast computations. Frekvens also comes with a high and low pass filter and a lfo for modulating the delay play head.
