What SpectraView Meter is
SpectraView Meter is a free macOS plug-in for monitoring audio in real time inside a DAW. It analyzes a signal without changing its sound, combining stereo level and dynamic-range meters with loudness, frequency-spectrum, and waveform views. Its loudness analyzer follows EBU R128 and ITU-R BS.1770-4 and displays integrated loudness, loudness range, and true peak. The frequency analyzer can show octave bands from 1/1 to 1/24 or a linear spectrum; it also offers INST and RMS modes, tilt, smoothing, and peak hold. A live waveform display provides another view of the signal as it plays.
The plug-in comes in Audio Unit and VST3 formats and is listed for hosts including Logic Pro, Studio One, Universal Audio LUNA, Ableton Live, Cubase, Reaper, and Bitwig. It requires macOS 14 or later and runs on Apple Silicon and Intel Macs as a Universal binary. AAX, the format used by Pro Tools, is not included. The maker says the installer is signed and notarized. Its privacy policy says the plug-in does not transmit data to external servers and has no cloud processing, analytics, tracking identifiers, or advertising. The user guide lists support at [email protected].
