摘要： Methods, apparatus, and articles of manufacture are disclosed in which auxiliary information is added to or removed from an audio signal. In one example, the information may be added to the audio signal using at least two frequencies that are dictated by two different frequency transformation block sizes, such that the two frequencies are not fully visible when an incorrect block size is used to perform a frequency transformation. Additionally, in another example, a decoder may compensate for time and frequency affects caused by removing old samples and adding new samples, which, in one example, alleviates the need to perform repeated frequency transformation using different frequency transformation block sizes. Other examples are described.
摘要翻译：公开了将辅助信息添加到音频信号或从音频信号中移除的方法，装置和制品。在一个示例中，可以使用由两个不同的频率变换块大小指定的至少两个频率将信息添加到音频信号，使得当使用不正确的块大小来执行频率变换时，两个频率不完全可见。此外，在另一个示例中，解码器可以补偿由去除旧样本和添加新样本引起的时间和频率影响，在一个示例中，这样减少了使用不同频率变换块大小进行重复频率变换的需要。描述其他示例。

摘要： Methods and apparatus for characterizing media are described. A disclosed example apparatus includes a transformer, a decision metric processor, a signature determiner, and a processor to implement the transformer, the decision metric processor, and/or the signature determiner. The example transformer is to convert at least a portion of a block of audio into a frequency domain representation including a plurality of frequency components. The example decision metric processor is to: define a band of the frequency components; determine a difference in energy between a first convolution of a first complex vector with a first group of frequency bins in the band and a second convolution of a second complex vector with a second group of frequency bins in the band; and determine a decision metric for the band based on the difference. The example signature determiner is to determine a signature based on a value of the decision metric.
