Automatic pitch tracking EQ plug-in
Up until now EQ's were set to a fixed frequency range. In reality fundamental frequencies and the harmonic series change with the pitch of the instrument or vocal track. This characteristic makes the standard fixed-frequency EQ less effective when it is used to manipulate the instruments/vocals harmonics. SurferEQ tracks the pitch of the instrument or a vocal track and can change the EQ frequency accordingly in real-time making it possible for the first time to naturally control the fundamental frequencies or harmonics of a track. Just set any of the EQ bands to a desired harmonic and watch SurferEQ move with the track staying always relevant to the music.For over a year they've meticulously developed an accurate real-time pitch detection engine with virtually no octave errors. There's no need for endless parameters tweaking. It just works. When developing their original analog-behaving asymmetric EQ algorithms (No cookbook EQ here!) they've made every effort to preserve the size and energy of the original recording. SurferEQ sounds natural even when it is pushed to its extremes. In addition to the HP LP shelf and bell shaped filters they've developed a unique four mode harmonic filter. It takes on a whole new life when it moves with the pitch and makes it possible to achieve new sounds as never heard before. they are excited and proud to finally put their creation in your hands. they hope you'll find it inspiring and creative as they have.
