  title: ACRCloud API
  description: >-
    Specification of the ACRCloud automatic content recognition (ACR) APIs. The
    Identification API recognizes music, custom audio, live channels, and humming
    from a short audio sample or a precomputed fingerprint using HMAC-SHA1 signed
    requests. The Console API (api-v2.acrcloud.com) manages buckets, audio files,
    file-scanning containers, and broadcast-monitoring projects using bearer-token
    access tokens, and the external Metadata API enriches tracks with third-party
    music metadata.
