Extract the harmonics. Not a pitch shift. The real thing.
Every pitch and harmony effect on the market generates new content: shifted octaves, synthesized intervals, artificial harmonics. None of them extract what's already there.
Sieve isolates the natural harmonics present in any audio signal. The same harmonics you hear when you touch a guitar string at the 12th fret. But electronically, in real time, on any instrument.
Separate the harmonics from the fundamental. Apply different effects to each. Distortion on harmonics only, with a clean fundamental underneath. Reverb on just the upper partials. Delay on the overtones alone.
This is not one effect. It is a platform for an entirely new category of sound processing.
Expression pedal control sweeps continuously through harmonic nodes: 12th fret, 7th fret, 5th fret, and beyond. Like running your finger up the string, but with a foot.
Each harmonic node isolates different partials from the signal. Here, each node gets its own effect to showcase its unique character. Start with the dry signal, then explore each node.
Unprocessed electric guitar. A110, all harmonics intact.
Continuous sweep from fundamental through all harmonic nodes. Like running your finger up the string, but with a foot pedal.
17 real recordings (Hendrix isolated guitar, vocals, acoustic) processed at 9 pedal positions each.
Request Sample AccessHeavy distortion on the harmonic bus while the fundamental stays clean. A sound that has never existed before.
Reverb on just the upper partials. Dry attack, lush harmonic tail. Clarity and space at the same time.
Spectrograms show the frequency content of the signal over time. You can literally see the harmonics being isolated.
Guitar: Node 2 harmonic isolation. Odd harmonics removed, even harmonics preserved.
Guitar: Expression pedal sweep through all harmonic nodes. Watch the partials appear and disappear.
Distortion on harmonics only. The fundamental stays clean while the upper partials get crushed.
Once you can separate harmonics from the fundamental, you can process them independently. Every classic effect becomes something new.
A sound nobody has heard before. Expression pedal control for live performance. Works with guitar, bass, keys, voice, strings.
New textures for mixing and sound design. Isolate and process harmonic content independently. Available as a plugin (coming soon).
License the patented algorithm for your hardware platform. We provide the DSP. You provide the enclosure, the brand, and the distribution.
