Growl Audio has released an update to its powerful and flexible spectrum analyzer for modern audio production.
Version 1.2.0 of gFractor adds a new waterfall view, band audition, a split spectrum layout, smoothing and tilt controls, draggable curve ordering and a mono-sum channel mode, alongside a reorganised settings layout, a reworked light theme, a new about dialog and performance work across the oscilloscope and analyzer.
gFractor is a measurement plugin (VST3 / AU / Standalone) you put on any bus to see what’s in your audio. It shows two views — a spectrum analyzer and a tempo-synced oscilloscope — over three channel decompositions (Mid/Side, Left/Right, Tonal/Transient), with a goniometer + correlation + width-per-octave metering panel and a full ITU-R BS.1770-4 LUFS meter alongside. It does not colour the audio unless you tell it to: a gain stage, a dry/wet mix, and an audition bell filter are the only signal-path controls.
Insert it post-fader on a master bus or any group whose tonal/stereo balance you want to monitor.
