foo_vis_wispan is a Foobar2000 spectrum analyzer visualization implemented with GDI. It is a port of the Classic Spectrum Analyzer (vis_classic) Winamp visualization plug-in by Mike Lynch.

Features:

• Accurate, detailed, customizable spectrum analyzer.
• vis_classic library has been upgraded to compile with a modern toolset.
  • Upgraded the resolution of the waveform passed into the library from 8 bits to 16 bits.
  • Other changes are mainly to integrate with foobar2000 instead of Winamp.
  • That means bugs in the original are still likely to be present.
• Options can be modified and their effects viewed in real-time as the component is running.
• Compatible with the Default User Interface (Default UI) and the Columns User Interface (Columns UI).
• Tested on foobar2000 v2.25.3 (x86 32-bit and x86 64-bit) and Microsoft Windows 11 (Build 26200).
