Plugin Boutique Scaler EQ v1.0.0 (Win/macOS)

By enhancing only note frequencies in key with your song, and reducing only note frequencies that aren't, Scaler EQ can provide a new spin on working with cuts and boosts, increasing the tonality behind your music and providing new harmonic avenues.
And for when you just want a regular, fully-featured, modern EQ, Scaler EQ has you covered with its familiar workflow, large choice of band types, mid/side operation, dynamic bands and stereo enhancement. You can easily apply classic mixing and mastering techniques used by professionals, with an extra optional musical edge.
What can Scaler EQ be used for?
Music Production: Ideal for musicians and producers looking to enhance the musicality of their tracks by ensuring all instruments are in harmony with the chosen scale.
Audio Editing: Simplify EQ processes by targeting and cleaning up frequency bands to remove audio that doesn't belong and enhance audio naturally present with the chosen scale.
Audio Engineering: Dynamically soothe audio by suppressing in-harmonic frequencies or expanding harmonic frequencies using dynamic compression and expansion.
Mastering: Place on your master channel to broaden your stereo width, focus your bass and enhance your mix.
DJing: DJs can use it to ensure that the tracks they mix are in harmony by detecting the key and scale whilst balancing the mix of each track.
