• Spectral Analyzer audio plugin based on the Constant-Q transform.
  • Offers equal resolution over all octaves and displays one value for each of the 12 notes within the equal-tempered scale
  • The original intention for this plugin was to serve as visualization for my CQT implementation, I’m not so sure yet how useful it is in an actual music production context.


  • The plugin is completely open-source:


  • In general I’m happy about any kind of feedback, questions or suggestions.
