    • Multiple information is extracted from an unknown recording and information associated therewith. Associated information includes the filename, if the recording is a computer file in, e.g., MP3 format, or table of contents (TOC) data, if the recording is on a removable medium, such as a compact disc. At least one and preferably several algorithmically determined fingerprints are extracted from the recording using one or more fingerprint extraction methods. The information extracted is compared with corresponding information in a database maintained for reference recordings. Identification starts with the most accurate and efficient method available, e.g., using a hash ID, a unique ID or text. Fingerprint matching is used to confirm other matches and validation is performed by comparing the duration of the unknown and a possibly matching reference recording.
    • 从未知记录和与其相关联的信息中提取多个信息。 如果记录在例如光盘的可移动介质上,则相关信息包括文件名,如果记录是例如MP3格式的计算机文件或目录(TOC)数据。 使用一种或多种指纹提取方法从记录中提取至少一个并且优选几种算法确定的指纹。 提取的信息与维护参考记录的数据库中的相应信息进行比较。 识别以最准确和最有效的方法开始,例如使用散列ID,唯一ID或文本。 指纹匹配用于确认其他匹配,并通过比较未知的持续时间和可能匹配的参考记录来执行验证。
