  title: AudD Music Recognition Custom catalog API
  version: 1.4.4
  description: 'The AudD music recognition API identifies songs from short audio clips

    (`api.audd.io/`), large audio/video files (`enterprise.audd.io/`), and

    real-time audio streams (callback or longpoll based on `api.audd.io/`).


    This OpenAPI document is the canonical contract for the API. Every

    official AudD SDK validates its parser against the fixtures shipped

    alongside this spec.

      description: '⚠ **This is NOT how you submit audio for music recognition.** For

        recognition, use `POST /` (or `POST enterprise.audd.io/` to scan

        beyond the first 12 seconds of a file). This endpoint adds a song to the caller''s

        private fingerprint catalog so AudD can later identify it for the

        caller''s account only.


        Requires special access — contact api@audd.io to enable.


        Calling `upload` again with the same `audio_id` re-fingerprints that

        slot. There is no public list/delete endpoint; callers track

        `audio_id` ↔ song mappings on their side.'
