Thanks to our exclusive modeling technology - TAE® and Phi® - we’re able to deliver unparalleled accuracy and sonic authenticity, right down to the behavior of individual components.

From the Marinair transformers that formed the basis of Comp DIODE-609’s warm sound, to the retired European broadcast tech that inspired EQ SITRAL-295, the real magic lies in the details - and now that magic is in your hands.

It doesn’t stop with the modeling, however. Our DSP engineers, sound designers, and product experts always enhance these incredible effects, with both deep respect to the original hardware and an awareness of the needs of contemporary producers - ensuring that our software delivers far more than its studio predecessors.
