AudD

AudD is a music recognition service that identifies songs from audio files, URLs, or microphone input via a simple REST API. The api.audd.io API returns rich track metadata (artist, title, album, ISRC, links to Apple Music, Spotify, Deezer and more), supports recognition by humming/singing, lyrics search, and an enterprise endpoint for scanning long audio and video files.

AudD publishes 2 APIs on the APIs.io network: Lyrics API and Recognition API. Tagged areas include Music, Music Recognition, Audio, Fingerprinting, and Lyrics.

AudD’s developer surface includes authentication, documentation, and 8 more developer resources.
