Audio leveling and enhancement device

A method for leveling and enhancing an audio portion of an audio-visual signal, comprising:

• (a) reducing the volume of the audio portion;
• (b) duplicating the audio portion to provide at least one exact copy of the audio portion, the audio portion defining a first signal layer, the exact copy defining a secondary signal layer including at least one equivalent secondary signal of the audio portion;
• (c) separating the audio portion and the equivalent secondary signal, each as a whole, into two separate identical signal layers;
• (d) reducing the amplitude in each of the signal layers;
• (e) synchronously processing the identical signal layers by;
• (i) sequentially processing each of the signal layers with at least two pieces of equipment selected from the group consisting of a limiter, an expander, a compressor, and an equalizer, one of the signal layers being processed within a first range of frequencies and the other signal layer within a different range of frequencies;
• and
• (ii) reducing the volume of each of the signal layers as a whole when each signal layer is transmitted from one of the above pieces of equipment to another of the above pieces of equipment;
• (f) merging the processed signal layers at an equalizer;
• (g) processing together simultaneously the merged signal layers through at least a limiter and a master fader and then outputted, and wherein the time for processing each of the signal layers is the same.
