SURFEREQ follows the pitch of a monophonic instrument or vocal in real-time and can adjust any of its bands accordingly, thus "Surfing" the sound waves.
SURF ON
Any of SURFEREQ's seven bands can be set to SURF mode to track the pitch of the instrument or vocal source and adjust its frequency relative to the notes being played.
Furthermore, SURFEREQ's pitch can be controlled via MIDI notes, allowing its EQ bands to be played using a keyboard, thus creating a unique timbre-shaping musical instrument.
UNIQUE FILTER ALGORITHMS
We've made every effort to preserve the size, energy and transients of the sound source while developing SURFEREQ's filters algorithms (No cookbook EQs here!). SURFEREQ's analog-like, asymmetric filters sound natural even when pushed to extremes.
In addition to the HIGH-PASS, LOW-PASS, SHELF and BELL-shaped filters, we've developed a unique, four-mode HARMONIC FILTER which enables to control the entire harmonic series of an instrument using just a single band of EQ.
SUPERIOR PITCH DETECTION
One of the biggest challenges in designing a real-time pitch-detection algorithm is avoiding octave errors while keeping the algorithm efficient enough for real-time processing. We've spent over a year researching and meticulously developing an accurate, real-time pitch-detection engine with virtually no octave errors.
