SpectraView Meter
A real-time metering plug-in for your DAW. Insert it on a track, bus or the master and read loudness, spectrum, level and dynamics at a glance: the loudness and spectrum engine of SpectraView Studio, live inside your session. Free.
One window, four ways to read your audio.
SpectraView Meter is a measurement insert: it analyses the signal passing through it and changes nothing about the sound. In a single window it stacks a stereo level meter with a live dynamic-range bar, an EBU R128 loudness analyzer, a real-time frequency analyzer and an oscilloscope-style waveform, so a glance answers "is my loudness on target, and where is that energy coming from?"
- Level & dynamic range: stereo level bars with peak-hold and clip flash, plus a floating dynamic-range bar colour-coded by crest factor.
- Loudness: scrolling EBU R128 / BS.1770-4 timeline with Momentary, Short-term, Long-term and RMS curves, target reference lines and live INTEGRATED / SHORT-TERM / LRA / MAX TRUE-PEAK readouts.
- Frequency analyzer: real-time FFT spectrum in 1/1 to 1/24-octave bands or linear, with INST / RMS modes, tilt, smoothing and peak hold.
- Live waveform: an oscilloscope-style L / R strip for a quick read of transients and gain staging.
Broadcast-grade loudness, right in the mix.
- Integrated LUFS with full two-stage gating per ITU-R BS.1770-4.
- Short-term, Momentary and Long-term loudness curves over a scrolling timeline.
- True-Peak with oversampling, and Sample-Peak, switchable, with max-peak readouts.
- Loudness Range (LRA) for the live dynamic spread.
- Target reference lines for −14 / −16 / −23 LUFS, plus a free custom target.
There's an iPad app, too.
SpectraView Studio is the file-based companion on iPad and Apple Silicon Mac: waveform, spectrogram, loudness metering and a frequency analyzer for any audio file, free on the App Store. The Meter plug-in brings the same DSP core into your DAW as a live insert.
