Spectrum Analyzer Visualisation

By: oops

foo_vis_wispan is a 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 (x86 32-bit and x86 64-bit) and Microsoft Windows 11 (Build 26100).

Limitations

It still runs at a maximum vertical "window" size of 255 pixels.
It still uses the INI files to save settings.
Only 1 instance of the component is supported.
FFT equalization is negative logarithmic (base e) curve.
It only includes minimal bug fixing in the original library.
The component assumes Windows 10 as a minimum.

Installation

Install the component using the "foo_vis_wispan.fb2k-component" file that can be downloaded from this page.
Profiles are placed in this component's folder of foobar2000. This should be "<foobar2000 profile folder>\wispan".

Current version: 0.0.1-alpha0, released on 2025-09-02
