About smart:EQ 4

smart:EQ 4 is an AI-assisted equalizer plugin designed for professional audio mixing, featuring intelligent spectral processing and cross-channel communication to balance frequency responses across multiple tracks.

smart:EQ 4 by Sonible is a sophisticated AI-powered equalizer plugin tailored for audio engineers and music producers seeking efficient, high-quality mixing solutions. Its standout capability is its intelligent spectral processing, which automatically analyzes audio material to suggest balanced EQ curves, significantly speeding up the mixing process. Beyond standard equalization, it features advanced cross-channel communication, allowing users to manage frequency masking between different tracks directly within the plugin interface. The plugin supports dynamic EQ, mid-side processing, and linear phase modes, providing the flexibility needed for both corrective and creative tasks. While it is a powerful tool, users should note that its advanced AI features require a learning curve to fully master. Pricing is transparently listed on the Sonible shop, and the company provides extensive support through tutorials, user guides, and direct contact channels. It is a robust choice for professionals looking to integrate AI-assisted workflows into their mixing sessions.
