Saying that a signal is some number of dB is meaningless without a reference point! For example, dBV, dBu, and dBm are all useful for measuring electrical signals. Since we are dealing with digital audio, we are mainly concerned with two measures: dBFS and dBSPL. The first is dBFS, or decibels full scale. The highest possible level of sound produced by audio equipment is 0 dBFS. All other levels are expressed in negative numbers. dBFS is described mathematically as: dBFS = 20 * log( [sample level] / [max level] ) The maximum dBFS value in a 16-bit audio system is: max = 20 * log(1111 1111 1111 1111/1111 1111 1111 1111) = log(1) = 0 Note that the maximum dBFS value will always be 0 by definition, since log(1) = 0.
