Mercurial Tones releases Scepter Pro analyzer for €59

Five specialized audio-analysis views crammed into one plug-in just dropped, and there is a free version if you only need the spectrum analyzer.

Mercurial Tones launches Scepter Pro

• Scepter Pro is a referencing and analysis workstation plug-in.
• Specter Lite ships free with just the spectrum analyzer.
• Introductory pricing sits at €59, jumping to €89 later.
• macOS and Windows get VST3, AU, and standalone support.

Spectrum and reference tools go hard

• Real-time spectral analysis runs with zero-stutter fluidity.
• Mid/side imaging exposes stereo-field problems instantly.
• Reference matching auto-aligns loudness for fair comparisons.
• A spectral-diff view pinpoints exact frequency imbalances.

Bass, loudness, and scope round it out

• Tempo-synced bass monitoring tracks everything below 250 Hz.
• Phase monitoring confirms low-end mono compatibility fast.
• Tri-band color-coded loudness metering is a genre-first feature.
• Sidechain comparison on the oscilloscope overlays two signals.
