Echobode combines frequency shifting with delay to produce unique sound transformations. Unlike pitch shifters, this frequency shifter moves the audio spectrum in a linear fashion, which alters the harmonic structure of sounds. For example, shifting overtones from 100, 200, and 300 Hz by 50 Hz results in inharmonic tones that can generate metallic and bell-like timbres. Integrating this effect within a delayed feedback loop further expands its creative potential by adding rhythmic and spatial dimensions.

The underlying frequency shifting algorithm draws inspiration from the classic Bode device, known for its precise sideband separation and innovative approach to preventing unwanted frequency reflections outside the audible spectrum. The delay section incorporates high-quality all-pass interpolation, ensuring smooth and natural echo effects. Additionally, a built-in low-frequency oscillator (LFO) allows modulation of the delay time or frequency shift, enabling dynamic and evolving soundscapes.

Echobode offers a wide range of sound design possibilities, ranging from straightforward frequency-shifted echoes to complex modulation effects such as phasing, flanging, and chorus. This makes it a powerful tool for musicians and producers seeking to add distinctive textures and movement to their audio, whether for experimental sound design or enhancing traditional musical elements.
