GT Analyzer is a highly configurable spectrum analysis tool with a streamlined and gorgeous looking interface. The developers emphasize GT Analyser’s low-end analysis precision and high-resolution frequency spectrum display as its standout features.
The user can tweak the plugin’s visual components in order to adapt the real-time spectrum display different monitoring scenarios. Parameters like the graph decay and hold times, the dB range, and block size are all configurable. These parameters can be accessed by clicking the gear icon in the upper-right corner of the front panel. The control knobs can be hidden in the same manner to reduce the UI size and allow the user to focus on the analysis window.
Even though SPAN by Voxengo remains my favorite freeware spectrum analyzer, I thoroughly enjoyed using GT Analyser as a lightweight and great-looking alternative. The current version of the plugin could be improved upon with a resizable GUI and a way to change the screen colors, although the current color scheme is indeed quite pleasing.
GT Analyser can be downloaded directly from Gramotech’s website. You won’t need to sign up for a user account or spend time activating the software. At the moment, GT Analyzer is only compatible with VST3 and AU plug-in host applications. There’s no info on whether or not the VST2 version of the software is in the works.
The team at Gramotech is also offering an affordable equalizer plugin called Babylon (£30). It features eight fully automatable filter types and a high-resolution spectrum analyzer that is similar to GT Analyser.
GT Analyser is available for free download via Gramotech (1.91 MB download size, ZIP archive, 64-bit VST3/AU plugin format for Windows & MacOS).
