🎛️ AI Plugins Reviewed: Pros & Cons

As AI continues reshaping the music workflow, these five plugins are getting serious traction from engineers and producers alike. Here’s a candid breakdown of what works, what doesn’t, and who it’s (really) for.

1. iZotope Neutron 5 (Mix Assistant)

Pros

  • The AI-powered Mix Assistant analyzes your multitrack session to auto-balance levels, EQ, compression, stereo placement, and more.

  • Includes powerful modules like Unmasking EQ, Density (upward compression), Phase alignment, and Clipper for advanced fine-tuning.

  • Great for both beginners and seasoned engineers thanks to intuitive workflow and deep adjustability.

Cons

Best For: Fast rough-in sessions, mix templates, and educational learning tools.


2. LANDR AI Mastering Plugin lndr

Pros

Cons

  • Limited options for custom tweaking or creative tone tailoring.

  • Reliability depends on source material quality—complex mixes can expose AI limitations.

Best For: DIY artists needing instant mastering without technical overhead.


roex ai3. RoEx Automix AI

Pros

Cons

  • Minimal control over sonic character—more “one-button” than an engineering tool.

  • Best used as a starting point; often requires manual polish afterward.

Best For: Quick demos or early-stage tracks where polish isn’t priority zero.


4. Sonible smart:EQ 4

Pros

Cons

  • Doesn’t address compression or spatial mix elements—EQ only.

  • May lack nuance for more creative or colored tonal shaping.

Best For: Engineers dealing with dense mixes or mask-heavy sessions.


5. Neural DSP Mantra (Vocal AI Channel) neural dsp

Pros

  • All-in-one vocal tool offering pitch correction, harmonization, sculpting EQ, saturation, compression, and FX.

  • Features “Sculpt” module: AI-driven EQ/dynamics shaping based on genre presets.

Cons

  • Module order is fixed—limits flexibility in vocal chains.

  • Some vocal corrections are only available in mono, which may confuse stereo workflows.

  • Designed more for performance than full mix automation contexts.

Best For: Solo engineers and producers needing powerful vocal processing in one interface.
