Mastering Plugins and Tools Compared: Ozone, FabFilter, Stock DAW, and Meters

Mastering plugins compared: iZotope Ozone, FabFilter Pro-Q/L, Waves, stock DAW tools, and essential meters for LUFS and true peak.

Mastering plugins span all-in-one suites (iZotope Ozone), best-in-class individual tools (FabFilter Pro-Q 3, Pro-L 2), and capable stock DAW processors. The methodology — EQ, dynamics, limiting, metering — matters more than brand names.

Key takeaways
  • Essential trio: parametric EQ, bus compressor, true-peak limiter
  • Must-have meter: integrated LUFS + true peak (Youlean free, Insight, Pro-L meter)
  • Ozone: full suite with EQ, dynamics, imager, maximizer — industry standard
  • FabFilter Pro-Q 3: surgical and M/S EQ; Pro-L 2: transparent true-peak limiting

All-in-one vs modular chains

iZotope Ozone bundles EQ, compression, stereo width, limiting, and AI assist in one interface — efficient for home and pro workflows. Modular chains (separate EQ + comp + limiter) offer maximum control and match traditional studio routing.

Limiters worth knowing

FabFilter Pro-L 2, Weiss DS1-MK3 (hardware), Tokyo Dawn Limiter 6, and DAW stock limiters all work when configured with true-peak oversampling and −1 dBTP ceiling. See True Peak Limiting and When to Use Limiters.
