Surgence Meter

Visual analysis & metering

When you need a clear picture of your mix, Meter buffers audio and analyzes it away from the audio thread—FFT spectrum (mel, log, or linear), scrolling or static spectrogram, dual-trace oscilloscope with pitch-follow, stereo field views with correlation, classic VU, and K-weighted loudness-style windows plus stereo RMS. Lay out Quad, Row, Stack, or a custom snap grid; overlay a reference track’s spectrum; on macOS, optionally meter system output in plugin or standalone.

Confidence you can see

When ears fatigue, meters keep decisions honest: stereo width, peak behavior, spectral tilt, and low-end buildup all show up before they wreck a print.

  • One window, many viewsSwap tiles between spectrum, spectrogram, scope, stereo field, and levels without juggling separate plugins.
  • Teach and translateStudents and clients grasp imaging and spectrum faster when the display matches what you are describing.
  • Compare to a referenceLoad a mastered or raw file and average its spectrum into the same bins as your live signal.

"I keep Meter on the master while printing. Correlation, spectrum tilt, and the spectrogram catch problems I would miss after hours at the same level."

Jordan Reeves - Mix Engineer

Depth without clutter

Every tile exposes the controls that matter for that view—ballistics, channel selection (L/R/Mid/Side), and display modes stay close to the glass.

Spectrum detail

FFT bars, color bars, or both; adjustable smoothing and peak decay; channel modes for mid-side checks at a glance.

Spectrogram workflow

Optional piano overlay and frequency lines for pitch context; sharper or classic detail presets; horizontal or vertical time flow.

Time and space

Oscilloscope traces with multi-band or mapped color; stereometer paths from scaled energy to Lissajous; correlation in single or multi-band modes.

Levels you trust

VU calibration offset, user-defined peak and clip LED thresholds, K-weighted short and longer LU-style windows, and stereo RMS with selectable time constants.

Tech info

Analysis features

  • Analysis runs on a separate thread from a stereo buffer—FFT, spectrogram, scope, stereo, and loudness stay off the audio callback
  • Layout: Quad, Row, Stack (strips), Custom snap grid; per-slot meter choice
  • Spectrum scales: Mel, Logarithmic, Linear; FFT sizes 1024–16384
  • Loudness: K-weight LU (~400 ms), K-weight LU (~3 s), Stereo RMS (300 ms / 1 s)
  • Reference spectrum from imported audio (async decode to display bins)
  • Optional macOS system-audio capture into the same buffer (plugin or standalone)

System and formats

  • macOS + Windows support
  • VST3, AU, and standalone (standalone includes macOS system-output tap)
  • 64-bit stereo pass-through with bypass
  • Separate visual peak/smoothing release for stable ballistics during playback

Best for: master bus monitoring, mix translation checks, stereo imaging audits, education, and sound-design timbre matching.

Stop guessing what is in the signal.

Add Surgence Meter and keep spectrum, stereo, and level behavior visible from first idea to final print.
