A recreation of Musical Spectrum component for foobar2000 v2.x and 64-bit versions.

Configuration

You can tweak the configuration by creating a foo_vis_spectrum_analyzer.json next to the foo_vis_spectrum_analyzer.dll file. The content of the file is reread at the start of a new track.

You can find the foo_vis_spectrum_analyzer.dll in your foobar2000 profile directory.
