Abstract:
Methods and apparatus for performing variable block length watermarking of media are disclosed. Disclosed example apparatus include means for selecting a first frequency from a set of frequencies based on a first symbol in a code, and for selecting a first block size based on the first symbol and the code, a combination of the first block size and the first frequency to represent the first symbol. Disclosed example apparatus also include means for synthesizing a code frequency according to the first block size and the first frequency. Disclosed example apparatus further include means for combining the code frequency with a first block of input audio samples of the audio having the first block size to form a block of encoded audio samples encoded with the first symbol, the code frequency and the first block of input audio samples to overlap in time.

Claim (Index 18):
The apparatus of  claim 17 , wherein the means for adjusting the stored components in the spectral characteristics table is to multiply an imaginary component of the frequency domain representation by a sine function of the first phase angle.
