Sound Radix SurferEQ

Sound Radix is happy to announce the release of SurferEQ, an innovative pitch-tracking equalizer AU, VST and RTAS plug-in. It is capable of locking onto a vocal or an instrument pitch and adjusting the EQ frequency to its fundamental pitch, or any of its harmonics thus “surfing” on the sound waves.

Sound Radix designed the EQ filters with new and original algorithms, making every effort to preserve the energy and size of the original recording. In addition to the HP, LP, shelf and bell shaped filters, they have developed a unique harmonic filter, which makes it possible to control the complete harmonic series using only a single band of EQ.

As it is always relevant to the sound source, SurferEQ is a tool like no other. It enables tone shaping in ways that were impossible to achieve previously by other tools.
