摘要：
Methods and apparatus to audio watermarking and watermark detection and extracted are described herein. An example method includes receiving a media content signal, sampling the media content signal to generate samples, storing the samples in a buffer, determining a first sequence of samples in the buffer, determining a second sequence of samples in the buffer, wherein the second sequence of samples is of substantially equal length as the first sequence of samples, calculating an average of the first sequence of samples and the second sequence of samples to generate an average sequence of samples, extracting an identifier from the average sequence of samples, and storing the identifier in a tangible memory.
摘要（中）：
本文描述了音频水印和水印检测和提取的方法和装置。 示例性方法包括：接收媒体内容信号，采样媒体内容信号以产生样本，将样本存储在缓冲器中，确定缓冲器中的第一采样序列，确定缓冲器中的第二采样序列，其中第二序列 的样本具有与第一样本序列基本相同的长度，计算第一样本序列的平均值和第二样本序列以生成平均样本序列，从平均样本序列中提取标识符，并存储 标识符在有形存储器中。
