smart:EQ 4
AI-assisted EQ plug-in that balances tracks, reduces masking across channels, and provides dynamic, mid/side, and reference-based equalization.

smart:EQ 4 analyzes audio to correct spectral issues and improve tonal balance. Its smart:filter supports track, group, and track-and-group processing, while Group View lets users arrange up to 10 tracks and control EQ instances remotely.
It is designed for music producers, mixing engineers, sound designers, and mastering engineers. The plug-in includes instrument, vocal, genre, and reference-track profiles, plus dynamic EQ, Auto Gain, mid/side processing, and a 30-day fully functional trial. It runs inside compatible DAWs rather than as a standalone editor.
