audioMotion is a media player and high-resolution real-time audio spectrum analyzer that allows you to SEE your music! ♪♫🤩

It is completely free, open-source software, created out of my passion for the graphic spectrum analyzers of hi-fi systems from the 1980s.

Features:

• Decibel and linear amplitude scales, with customizable sensitivity
