Be detectable and insertable in as few as 30 seconds of the content. These requirements mean that the number of bits inserted is way beyond what the actual payload (data) is. A watermark may be just 32 or 64 bits but thousands and thousands of bits are inserted throughout the song acting as error correction and mitigation against the above.

According to this fact, the binary watermark bits are represented by two first order infinite impulse response (IIR) all-pass filters, whose transfer functions (in z-transform) are given by. H w ( z) = − b w + z − 1 1 − b w z − 1, where bw is the filter coefficient, 0 < b w < 1, and w ∈ { − 1, + 1 }.
