LIMITRON: Mastering Maximizer is a transparent look-ahead limiter, clipper and loudness maximizer for producers and mastering engineers who need finished, streaming-ready loudness without crushing the life out of the mix. Push level with three switchable engines — pure Clip, Hybrid transient-shaving, or a fully transparent look-ahead Limit — then stay in control with clean 3-band multiband processing, a true-peak-safe ceiling, ITU-R BS.1770-4 loudness metering and one-click streaming targets for Spotify, Apple Music, YouTube and more. Why it belongs in your session One plugin, finished loudness: clip, limit and maximize on the mix bus or in mastering, with a true-peak ceiling and streaming targets built in. Three engines, one workflow: Clip for fast, colorful density, Hybrid to shave transients into a smooth body, and Limit for the most transparent peak control. Loud without the pump: feed-forward look-ahead limiting and nine tuned profiles hold peaks while Punch metering shows exactly how much transient you keep. Controlled low end and stereo: 3-band multiband, Mid/Side mode and width keep bass, body and air translating on every system. The maximizer engine Three modes — Clip, Hybrid and Limit — each with its own detector and character. Nine limiter profiles: Auto, Transparent, Punchy, Dynamic, Allround, Aggressive, Modern, Bus and Safe. Feed-forward look-ahead architecture with adjustable lookahead up to 10 ms and program-dependent release. Clean 3-band multiband with fixed 120 Hz / 2.5 kHz Linkwitz-Riley crossovers, phase-aligned reconstruction and per-band gain-reduction metering. Spectral Tilt and Transient / Sustain controls shape how hard highs, lows and transients are pushed before the ceiling. Up to 64× internal oversampling with a True-Peak-Safe mode for a clean dBTP output. Metering and loudness ITU-R BS.1770-4 loudness: Integrated, Short-term and Momentary LUFS, plus Loudness Range (LRA). True-Peak (dBTP) metering at the oversampled rate and a clear gain-reduction display. Punch (transient retained %), stereo Correlation and dynamics readouts (PLR / PSR). Auto Loudness analysis with one-click targets: Spotify −14, Apple Music −16, YouTube −14, Tidal −14, Club −9 and Broadcast −23 LUFS. LEVEL, CURVE, SPECTRUM and 3D scopes with a 3-band HIGH / MID / LOW view and Delta Solo to audition only what is being removed. Built for real work Use it as a mix-bus maximizer, a mastering limiter, a transparent safety limiter or an aggressive clipper. Gain Match for true level-matched A/B, Unity Gain audition, DC filter, dither (16 / 24-bit) with selectable noise shaping and an optional external sidechain trigger. Stereo or Mid/Side processing, width control and independent channel / release linking. Scalable interface, 26 host-automatable parameters and stable session recall. Compatibility VST3 and AU on macOS, VST3 on Windows. Requires Windows 10/11 x64 or macOS 11+ on Intel or Apple Silicon. The Windows GUI uses the Microsoft Edge WebView2 Runtime; the installer includes the WebView2 bootstrapper when needed. One license covers up to three of your own computers.
