Sonible true:balance

The deal

$49 at PluginFox (down from $69, a 29% discount). The sale runs through September 29, 2026.

What it is

true:balance is a spectral balance metering plugin from sonible that analyzes the frequency distribution and mono compatibility of a mix in real time. It displays a live spectrum next to a running average, and lets you compare both against genre-based reference curves or up to eight of your own custom reference tracks. A separate channel data section reports stereo width and correlation values, so you can spot mono compatibility problems before they show up on a phone speaker or club system.

Who it's for

Mixing and mastering engineers who want an objective, visual check on tonal balance across a project, and home-studio producers who aren't sure whether their mix's low end, midrange, or top end lines up with commercial references in their genre.

Key features

• Real-time spectrum analyzer paired with a running average display for tracking balance over time
• Genre-based reference curves alongside support for up to 8 loaded custom reference tracks
• Balance Check that compares your mix to the chosen reference and returns text-based suggestions for closing the gap
• Mono Check that flags stereo-to-mono compatibility issues in the signal
