gFractor
gFractor is a free audio analysis app and plugin for macOS that helps producers and engineers inspect spectrum, stereo image, loudness, and waveform behavior.
What is gFractor?
gFractor is an audio analysis tool for music production, mixing, and mastering. It is developed by Growl Audio and runs on macOS as a standalone app as well as an AU and VST3 plugin, letting users inspect audio directly inside a DAW or in a separate desktop window. The app combines a real-time spectrum analyzer, oscilloscope, waterfall display, stereo metering, and LUFS loudness metering in one workspace. It supports multiple analysis perspectives including Mid/Side, Left/Right, Transient/Tone, and mono-sum monitoring, which makes it useful for checking balance, width, phase, dynamics, and tonal content during production work. gFractor is aimed at producers, mix engineers, mastering engineers, and other users who want detailed visual feedback while shaping or evaluating audio.

Safety overview
Status: Safe
gFractor is normal creative audio software for analysis and metering. Its audio monitoring features are consistent with its purpose, and the publisher states that the software does not require registration or send audio off the machine. Removing it will mainly affect your ability to use the standalone app or the plugin in your DAW, and saved presets or exported images may no longer be available from within the app afterward.
Recommendation: Keep gFractor if you use it for music production, mixing, mastering, or audio metering. If you no longer use the app or its plugins in any DAW, you can remove it like other third-party creative software.
