The smart EQ plug-in for audio editing balances spaciousness and unlocks creative possibilities in the post-production of music and language.

Revolutionary learning ability powered by the sonible smart:engine

Groundbreaking possibilities in audio processing


Frequency-selective transient design

The entropy:EQ separates harmonic and inharmonic components of your recording at any frequency range. This greatly simplifies the postprocessing of impact noise created by drums, guitars and other plucked instruments. Speech intelligibility, too, can be effortlessly improved by deliberately increasing noisy consonant sounds.
