Mercurial Tones releases Scepter Referencing & Analysis Workstation Plugin (and free Lite version)

Mercurial Tones has released Scepter Pro, a referencing and analysis workstation plugin for macOS and Windows in VST3, AU and standalone formats along with Specter Lite, a free version featuring the spectrum analyzer section.

Scepter features five specialized views for spectral analysis, reference matching, bass monitoring, oscilloscope, and loudness metering in one plugin.

Spectrum

Fluid, real-time spectral analysis:

• Fluid Motion: Buttery-smooth spectrum visualization that moves with your music. No stutter, no lag - just clarity.
• Mid/Side Imaging: Instantly reveal what's in the center and what's in the sides. Stereo problems become obvious.
• Adaptive View: Intelligent slope correction gives you a flat, intuitive reading - so you mix with your eyes as confidently as your ears.
• Precision Readout: Hover anywhere for instant frequency, level, and musical note. Every detail, one glance.

Reference

Match any track's frequency balance, stereo image, and dynamics in real time:

• Instant Matching: Load any reference track or route live audio. Loudness is automatically aligned so you're always comparing tone, not volume.
• Spectral Diff: A dedicated difference view highlights the exact frequencies where your mix sits above or below the reference - a clear map of what needs attention.
• Stereo Field Compare: See exactly how your stereo image stacks up against your reference across the full spectrum.
• 4-Band Dynamics: Per-band compression comparison reveals where your mix is over-processed - or not processed enough.

Bass Envelope

Tempo-synced bass monitoring that shows you exactly what's happening below 250 Hz:

• Tempo-Locked: Perfectly synced to your DAW. Watch your kick and sub unfold beat by beat.
• Bass Spectrogram: A living heat map of your low end. See sub energy, harmonics, and movement over time.
• Phase Monitoring: Know your low end is mono-compatible before it hits the club system.
• Sub Weight: Visual breakdown of where your bass energy sits. Instantly compare against any reference.

Loudness

See exactly what's eating your loudness, and fix it:

• Tri-Band Coloring: A first-of-its-kind color-coded loudness view. See low, mid, and high energy at a glance - nothing like it exists.
• Genre Targets and modular meters: Techno, hip-hop, pop, ambient - built-in loudness profiles for the genres you actually make. Modular meters let you build your own metering layout.
• Loudness Breakdown: Instantly see which frequencies are eating your headroom. Stop guessing, start fixing.
• Integrated LUFS and True-Peak: Broadcast-standard metering with real-time history. Master to any target with precision with True-Peak enabled.

Oscilloscope

Classic waveform view with sidechain comparison, and a spectral mode that splits your signal into three bands:

• Classic View: Clean, precise waveform display. See transients, phase, and stereo movement in real time.
• Sidechain Compare: Route a second signal and overlay it on your waveform. Instantly compare shapes and timing.
• Spectral Mode: Splits your waveform into low, mid, and high bands. See exactly which frequencies drive each transient.
• Tri-Band Waveform: Color-coded frequency separation on the scope. A view that no other oscilloscope offers.

Pricing & Availability

Scepter is available now for the introductory price of €59 (Reg. €89) for macOS and Windows in VST3, AU and standalone formats.
