The LFO can be tempo synchronized and put into stereo mode to generate inverse modulation for the right audio channel. Even with no frequency shifting taking place, Echobode is useful as a high quality echo effect with subtle phase smearing properties.Ī built-in sine LFO can be routed to modulate the frequency shifting amount, the phase shift or the delay time. ![]() The delay uses an “all-pass interpolation” technique that is low on aliasing and will preserve all the high-frequency energy of your source signal (even when time is being modulated). The delay time can be synchronized to tempo and it can be modulated to create chorus type effects. The sideband suppression technology introduces additional “phase shifting” that adds further to this effect. “beatings” and applying feedback (with a very short delay time) emphasizes this sound. Mixing a slightly shifted signal with the source signal creates phaser-like ![]() This stage also eliminates frequencies that are shifted up over half the samplerate (“nyquist”). If you want less suppression there is a “sideband mix” parameter that you can adjust, allowing you to create amplitude and ring modulation effects.Įchobode features a unique “anti-reflection” stage that removes “negative” frequencies (frequencies that are shifted down beyond 0 Hz and would otherwisebounce back into the audible spectrum). We are proud to say that Echobode features excellent suppression over the range of 40 Hz to 20 kHz. The challenge in creating a good frequency shifter lies in suppressing one of these sidebands (otherwise the effect sounds like a regular amplitude modulator). ![]() When a frequency shifter processes audio, two “sidebands” are generated, one that is shifted upwards and one that is shifted downwards. an overtone series of 100, 200, 300 Hz can be shifted by 50 Hz to 150, 250, 350 Hz, making the overtones inharmonic. The difference between a frequency shifter and a pitch shifter is that it shifts the audio spectrum linearly. Echobode is capable of creating many different effects from pure frequency shifting and echoes to phasers, flangers, choruses and more.
