An improved embedded signaling apparatus and method of embedding data into audio signals occurring at substantially zero decibel levels is disclosed. Embedding is accomplished at such low inaudible levels by modifying an embedded signaling encoder with a dither generator (64), dither adder (62) and dither subtracter (66) that generates, adds and subtracts dither signals, of equal magnitude, to audio signals at specified bit rates. |
