METER STACK

Real-time audio analysis plugin

Precision metering and spectral insight for modern producers, engineers, and sound designers.

Free

MeterStack layers waveforms, loudness, stereo field, and dual spectrum views into a single, calm interface so you can make faster, clearer mix decisions.

Built for speed, tuned for clarity, and designed to stay out of your way while you focus on the music.

A unified view for total clarity.

Waveform panel

Zoomable waveform for quick context, peak checks, and transient confidence without leaving the main view.

Stereo field panel

Instant read on width, balance, and correlation to spot phase issues before they become surprises.

Dual spectrum analyzers

Fast and slow overlays to compare impact versus body, perfect for EQ decisions and arrangement clarity.

MeterStack unified view interface
MeterStack loudness graph visualization

See your dynamics and loudness, layered.

A consolidated loudness view shows peaks, short-term, medium-term, and dynamic range together so you can balance competitive loudness with musical movement.

  • Peak
  • Medium-term loudness
  • Short-term loudness
  • Dynamic range

Two spectrum modes for any task.
