    摘要: An audio identification system generates a reference audio fingerprint associated with an event. The reference audio fingerprint is generated from samples of an audio signal associated with the event captured by multiple devices. To generate the reference audio fingerprint, fingerprints are generated from each sample, and the generated fingerprints are temporally aligned. Fingerprints associated a temporally overlapping portion of the audio signal are averaged, and the average value is associated with the temporally overlapping portion of the audio signal and included in the reference audio fingerprint. The reference audio fingerprint is stored along with identifying information, such as an event name, an event time, an event date, or other information describing the event associated with the audio signal from which the samples were captured.

    摘要: A method, apparatus and computer program product are provided to facilitate the review of audio files, such as in conjunction with the selection of one or more audio files. In the context of a method, one or more audio characteristics are determined for each of one or more audio files. The method may also include causing a visual representation of the one or more audio files to be presented for selection. The method may also include providing for at least one visual element representative of at least one of the one or more audio characteristics of the respective audio files to be displayed based on the determined one or more audio characteristics with the presentation of the visual representation of the one or more audio files.
