SEQ-S gives you powerful sonic sculpting and EQ matching up to 7.1 with stereo mid-side operation and automated spectrum analysis. Massage and correct any audio with incredible resolution that you just can’t get with a traditional parametric interface.

A direct-draw interface and detailed spectrum analysis make it easy to quickly identify and specifically fine-tune your audio. Couple this with EQ matching via sonic fingerprinting and you have some unique possibilities.

Beyond traditional EQ you can also use SEQ-S to capture the flavour of a piece of source audio and then transfer it to your current work – great for restoration and harmonisation work. Or use the same technique on individual tracks to unify different takes microphone positions and more.

The EQ Invert control gives you a minimally-invasive technique for creating space in a complex mix where traditional EQs are just too cumbersome. By ‘sampling’ the vocal and applying the inverted the curve to the backing specific space can be gently created without unnecessarily altering the original tonality of the underlying audio.

Unlike many linear phase EQs SEQ-S has a unique Quality Setting that gives it great precision in the low frequencies allowing you to make highly transparent adjustments without muddying the mix. The resolution is scalable to suit your task. Choose all the precision you need for demanding work during mastering or vary the setting to run multiple instances concurrently during a mixing session.
