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.

01 — Advanced Analysis Modes

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.

02 — Signal Comparison

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.

03 — Stereo Analysis

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.

Save a target.
Match it later.

Capture any Peak Hold curve as a reusable target and save it to a file. Load it back in any session to compare against your current track — perfect for matching tonal balance across mixes or checking a master against a reference.
