There’s a new spectrum analyzer plugin on the market from SIR Audio Tools to compete with the popular Voxengo Span analyzer plugin.
In both cases there’s a fully-capable free version and an upgraded paid version with some added features.
The SIR spectrum analyzer plugin is available for Mac and PC in both 32 and 64-bit.
It comes in AU, AAX, VST, and VST3 formats so it’ll work with just about anything.
The SIR spectrum analyzer has some cool features, like being able to view multiple tracks simultaneously.
It also includes a VU-Meter and stereo correlation meter, with intelligent peak-detection, mid and side signal detection, adjustable colors, and more.
Here’s a video demo of the free version from YouTube. See the website below for more details about the plugin.
