ABSTRACT:
An apparatus for indicating the level of digitally encoded audio data, in which a set of bits representing the audio signal amplitude are periodically latched in a latch circuit, with the resultant output bit signals from the latch circuit being displayed by means such as LED elements, with the period of repetitive latching operations being made to vary in accordance with the audio signal level, such as to increase in response to increases in that level.
