Spectrum 2 is a plugin available in VST, AU, and AAX formats designed to analyze the frequency content of audio mixes. It provides a clear and detailed view of frequency distribution, making it easier to identify overlapping frequencies and address mix imbalances. Users can insert multiple instances of Spectrum 2 at different points in their signal chain for comprehensive frequency analysis throughout their project.

The plugin offers two main visualization modes: a spectroscope and a spectrogram. These displays help users monitor frequency behavior over time, offering both real-time spectral data and historical frequency changes. The interface is optimized for speed with super fast graphics and allows customization through user-selectable colors and instance renaming for better workflow management.

Spectrum 2 supports flexible settings such as variable block size ranging from 2k to 16k, adjustable refresh rates between 40ms and 200ms, and spectral smoothing options from zero to eight seven. It features both manual and automatic ranging and can display frequencies in hertz or musical notes, providing detailed control and clarity for precise frequency inspection and mix cleanup.
