Turn audio into song metadata, then do something with it.
Worked guides for the AudD API — recognize music in clips, long files, and live streams. Build a Shazam clone, scan uploads for copyright, list a DJ set, monitor radio airplay. Copy a recipe, ship it.
End-to-end builds — from a blank file to a working thing.

Capture a few seconds of a Discord voice channel, send the clip to AudD, and reply in chat with the artist, title, and song_link.
Build a now-playing widget for a livestream
Show the currently-playing song on a livestream overlay using AudD audio streams, with a webhook callback receiver or longpoll, plus a copy-paste HTML widget.
Build a Shazam-style music identification app
Capture a few seconds of audio from the microphone and identify the song with AudD's standard recognition endpoint, including streaming links.
Detect samples and reuse of your own tracks
Detect when uploaded content reuses your own tracks — samples, leaks, or re-uploads — by matching against a private custom catalog with the AudD API.
Flag and remove music in a live-event recording
Find where copyrighted music plays in a long broadcast or livestream recording, flag each segment in a report, and produce a cleaned copy with those segments muted or cut.
Generate DMCA takedown evidence
Produce a structured evidence pack — track identification plus exact in-file timestamps — proving copyrighted music appears in a piece of content, ready for a DMCA filing.
Generate music credits for a podcast episode
Produce a timestamped music credits list for a podcast episode with the AudD enterprise endpoint, collapsing repeated matches into one credit per song.
Identify music in Instagram Reels and TikTok videos
Pass a social-media video URL straight to AudD's recognition endpoint to identify the music in a Reel, TikTok, or YouTube Short — no downloading required.
Monitor radio airplay for your music catalog
Track which of your catalog's songs get played across many radio stations 24/7 with AudD audio streams, storing every recognition and aggregating it into an airplay chart.
Scan an archive of audio files and write metadata back
Walk a directory of audio files, identify each one with AudD, and write artist, title, album, and ISRC to a resumable CSV.
Turn a DJ set or mix into a tracklist
Build a timestamped tracklist from a recorded DJ set or mix with the AudD enterprise endpoint, reading each match's file-absolute start time to place tracks and surface blends.
How the API works and how to choose between its parts.
Audio formats and quality for music recognition
Which audio and video formats AudD accepts, the 10 MB standard-endpoint cap, and practical guidance on clip length, sample rate, channels, and compression for reliable matches.
Controlling enterprise endpoint cost
How the AudD enterprise endpoint bills per 12 seconds of audio, and how limit, every, skip, and skip_first_seconds trade cost against completeness.
Interpreting the recognition score
Every AudD match carries a confidence score. How to read it and how to set application-specific thresholds for auto-accept, blocking, and human review.
Public database vs your custom catalog
When AudD recognition matches against the public 160-million-song database versus a private custom catalog you upload, and how to tell the two apart in a response.
Retries: what's safe to retry and what consumes a request
Which AudD API failures are safe to retry, which consume a request, and how to configure the SDK's retry budget without double-billing or duplicating catalog entries.
Standard, enterprise, or streams: how to choose
Pick the right AudD recognition surface for your input: standard for a short clip, enterprise for long files, streams for continuous live audio.
The song_link (lis.tn) universal music link
Every AudD match includes a song_link on the lis.tn domain; how its ?thumb and ?provider conventions and the SDK helpers let you build cover-art and 'open in your service' UIs without requesting provider metadata.
Webhook callbacks vs longpoll for stream results
Choose how to receive AudD stream recognition events: webhook callbacks when you can host a public HTTPS endpoint, longpoll when you can't.
Run recognition on a specific platform or runtime.
Add AudD to a podcast post-production pipeline
Wire AudD's enterprise endpoint into a repeatable podcast workflow — on every episode export, scan for music with ffmpeg, write credits to chapters and show notes, and flag unlicensed commercial tracks for review.
Add music recognition to a React Native app
Record a few seconds of audio in a React Native app, upload it to your own backend, and identify the song with AudD's standard recognition endpoint.
Add music recognition to an Electron desktop app
Capture a few seconds of audio in an Electron app and identify the song with AudD, keeping your API token in the main process and off the client.
Build a Chrome extension that identifies the music playing in a tab
Capture a few seconds of tab audio with a Manifest V3 Chrome extension, send it to your own backend, and identify the song with AudD.
Identify the music playing in a room with Home Assistant
Recognize the song playing in a room from Home Assistant or Music Assistant — capture a short audio clip on the server, send it to AudD, and expose artist and title as a sensor and a service you can automate on.
Run a Reddit music-recognition bot (the AudD RedditBot template)
Deploy AudD's open-source Reddit bot — the one that powers u/auddbot — to answer 'what's this song?' on posts and comments by recognizing music in linked videos and streams.
Run AudD music recognition in a Cloudflare Worker
Build a Cloudflare Worker that takes a URL or an uploaded file, calls the AudD API, and returns the recognized track as JSON — secret handling, fetch-based recognition, and CPU-time limits covered.
Run AudD music recognition in a Vercel function
Build a Next.js route handler on Vercel that calls the AudD API — covering the Node runtime (full SDK, including bytes) and the Edge runtime (fetch-only, URL or in-memory bytes), with timeout and offload guidance.
Run AudD music recognition in an AWS Lambda function
Build an AWS Lambda function in Node.js that identifies music with AudD, triggered by API Gateway or by new objects landing in S3.
Run the AudD Discord bot (deploy the official template)
Deploy AudD's official open-source Discord bot: clone the Go repo, configure your Discord and AudD tokens, run it, invite it to a server, and keep it up.
Show recognized music on a Twitch stream
Display the currently-playing song to Twitch viewers with AudD audio streams — subscribe a channel with addStream, consume matches via callback or longpoll, and render them in an overlay or a Twitch Extension.
Which capabilities map to the work you actually do.
