SpeAnaLED

About

• SpeAnaLED is a WASAPI(Windows Audio Session API) Loopback Spectrum-Analyzer-like visualizer with LED-matrix-like visualization. (L+R Max. 2 channels)
• "Loopback" means,
  • You don't need to load files,
  • You don't need mic,
  • You don't need line cables,
  • Simply use a PC sound card or device to play music on your favorite player, for example, foobar2000, Youtube or Amazon Music in various browsers, AppleMusic (iTunes), Spotify desktop app, etc., SpeAnaLED should intercept sounds and work.
  • In principle, it does not affect sound quality.
  • Conversely, the performance of your great playback device does not reflect.
• SpeAnaLED screens can be re-sized, so you can reside on your PC desktop by putting it on your "Startup" folder.
• SpeAnaLED is a tiny program. Its size of executable file is about 100KB itself, about 900KB including dlls. In the case of my 8 years old PC, CPU load is 0.1% or less, uses about 90MB process memory. No use of DirextX 2D, only GDI/GDI+ Win32API(System.Drawing(.Drawing2D)) is used.
• Yes, this is a one of "Reinventing the wheel" project.

Other precautions

SpeAnaLED is simply made to be seen and enjoyed by myself. The values including frequency displayed is most likely not accurate.

If a problem occurs, first try deleting your configuration file(SpeAnaLED.conf) and restart SpeAnaLED. (After that, enumerate sound device from setting dialog again.)

Have fun music!
