  title: ACRCloud Audio Files Buckets 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.
