gFractor
A powerful and flexible spectrum analyzer
for modern audio production.
What makes it different
Tools that think like musicians
From sound design to mixing and mastering — gFractor gives you precise visual feedback and deep insight into your audio at every stage of the workflow.
Three modes.
Every perspective.
Switch between Mid/Side, Left/Right, and Transient/Tone analysis to explore your signal from any angle. Monitor individual components — isolate transients from tonal content, or hear the mid and side channels in complete separation.
Main and sidechain,
side by side
Visually compare your main signal against a sidechain reference — instantly revealing spectral relationships between tracks. Swap main and sidechain with a single key press for rapid A/B analysis without breaking your flow.
Your stereo field,
fully mapped.
Comprehensive stereo visualization in one place: a goniometer for phase and imaging, a correlation meter for mono compatibility, and stereo width broken down per octave — so you know exactly where your width is coming from and where it isn't.
