What sonible smart:EQ 4 is
sonible smart:EQ 4 is a paid DAW plug-in for using AI to correct spectral issues and balance tone in tracks and mixes. Spectral mixing lets you drag up to 10 tracks into a group and assign foreground, middle, or background priorities. Any instance in a group can be controlled remotely from another instance. The smart:filter balances a signal against a Profile, with Smoothing, Adaptive processing, and controls for its analysis range. Track, Group, and Track and Group modes address channel balancing and masking between group members. Profiles cover instruments, vocals, and genres, and a reference track can create a custom profile. Standard EQ bands support dynamic behavior, alongside Auto Gain, Mid-Side processing, and an analyzer showing other instances in the same group. The plug-in supports 44.1 kHz to 192 kHz sample rates and native Apple Silicon. It runs on Windows and macOS, with machine-based or iLok authorization. There is no free plan, but registration provides a fully functional 30-day demo.
