ABSTRACT:
There is disclosed an apparatus for displaying in visual form the qualities of a musical signal. The signal is analyzed electronically into components based on the frequency characteristic or amplitude characteristic of the signal. Each component controls a motor operating a rotable indicator. Preferably the amplitude component causes rotation of the whole indicator display, which consists of three indicator sets, one for each of bass, treble and mid-range. Each indicator set may be sub-divided within further frequency limits.
