Max Mikhailov has announced the Seven Phases Spectrum Analyzer – real-time spectrum analysis VST plugin, is now open source and 64-bit.

The idea behind Seven Phases Spectrum Analyzer is an old-fashioned tool reminiscent of classic hardware analyzers of the earlier centuries.

Unlike most of other analyzers available these days, this plugin is not FFT-based but utilizes a filter-bank algorithms that mould its unique pros and cons.
