摘要：Described are techniques for determining whether a received audio signal iscorrupted or a product of noise, prior to decoding the entire signal. An emitted audio

signal may include initialization data, which includes a predetermined sequence ofsymbols, and which precedes encoded payload data. Correspondence between thepredetermined sequence of symbols and expected symbols stored as confirmation datamay be determined. If the correspondence indicates a match, an audio receiver maycontinue decoding the audio signal to access the payload data. If the correspondencedoes not indicate a match, the audio receiver may cease decoding, which may conservepower, computing resources, and time, ensuring that subsequent audio signals are notmissed while the audio receiver decodes a false or corrupted signal.
