INTRODUCTION Echobode is a delay effect with a frequency shifter placed inside the feedback loop. The frequency shifter algorithm is inspired by the classic Bode Frequency Shifter (named after its inventor Harald Bode). The difference between a frequency shifter and a pitch shifter is that it shifts the audio spectrum linearly. E.g. an overtone series of 100, 200, 300 Hz can be shifted by 50 Hz to 150, 250, 350 Hz, making the overtones inharmonic.
bounce back into the audible spectrum). This stage also eliminates frequencies that are shifted up over half the samplerate ("nyquist"). Mixing a slightly shifted signal with the source signal creates phaser-like "beatings" and applying feedback (with a very short delay time) emphasizes this sound. The sideband suppression technology introduces additional "phase shifting" that adds further to this effect. The delay time can be synchronized to tempo and it can be modulated to create chorus type effects.
User Interface Front RANGE Defines the behavior of the FREQUENCY knob (aka The Big Knob). FINE frequency shifting amount range from -200 Hz to 200 Hz WIDE frequency shifting amount range from -20 kHz to 20 kHz SYNC frequency shifting amount is synchronized to host tempo. This mode is useful when creating AM or phaser effects with short feedback delays. FREQUENCY knob lets you choose the synchronized rate with which a full cycle completes.
tremolo / amplitude modulation effect. There are also separate outputs on the backside for the two bands. ANTI REFL(ection) Enable the ANTI REFLECTION stage to eliminate harmonics that are shifted down below 0 Hz or beyond half the sample rate. Otherwise these frequencies will bounce back into the audible spectrum. The anti-reflection is implemented with a proprietary technology by Sonic Charge and has the same excellent quality as the sideband suppression.
MIX Mixes the wet and dry signal to your liking. Because of the phase distortion of Echobode, even a frequency shifting of 0 Hz will affect the sound although it is extremely subtle if you do not mix it with the dry signal. If you mix it you will hear the typical spectral "notches" and "phases" that you associate with a phaser effect. LFO Section TARGET The built-in LFO can affect FREQUENCY shift amount, PHASE adjustment or DELAY time.
User Interface Back Most of the inputs and outputs on the Echobode backside are straight forward and self-explanatory. The main exception is the FREQUENCY SHIFTER NOTE input. When you connect the NOTE input, Echobode will enter a CV pitch following mode where the frequency shift will follow the frequency of the CV note value you send to Echobode. With this feature you can do harmonic shifting on monophonic sounds ("monophonic" as in "non-polyphonic").
