Abstract: Disclosed is a method and an apparatus for embedding data in an audio signal based on a time domain, and a method and an apparatus for extracting data from an audio signal based on a time domain. The method for embedding data in an audio signal based on a time domain may include generating a time-domain insertion sequence from original data based on a weighting element, embedding the insertion sequence in a host audio signal, and transmitting the host audio signal in which the insertion sequence is embedded. The method for extracting data from an audio signal based on a time domain may include receiving a time-domain audio signal in which data is embedded, extracting a codeword from the audio signal, and synchronizing the audio signal based on the codeword.
