MiniMax EQ for Mac precisely measures the highest and lowest point in an audio track. In addition to working with sound files, it also has a premium feature that detects input coming from a microphone in real time. While the interface is well laid out, the lack of a file browser or drag-and-drop integration makes the addition of new tracks rather clumsy.
MiniMax EQ for Mac features a clean interface with just a handful of buttons. The app is quite basic, having no adjustable preferences. The biggest drawback is that file paths and filenames need to be entered or copied, manually; there's no drag-and-drop integration or a built-in file picker. Other than that, MiniMax EQ for Mac works well enough. One thing to note, though, is that the analysis of audio tracks is done in real time as the track plays, so longer tracks will take proportionally longer to be analyzed.
Filling a specific need, MiniMax EQ for Mac targets a limited group of users, which accounts for its lack of customization options. If you're working with sound and music a lot and need to know the highest and lowest level of a track, you will want to try it out. Otherwise, you probably don't need it.
