AudioLib - A developer audio infrastructure platform that allows single API access to massive music libraries.

What is AudioLib?

AudioLib is an audio version of OpenRouter launched by Yang Yue and the 43Music team. It provides developers with access to over 100,000 original music tracks created by the team over a year via an API. No SDK, player, copyright negotiations, or music library management are required. A single key and a music library name are all that's needed; a POST request returns a direct CDN audio link. The platform supports dozens of curated music libraries based on function (focus, sleep, workflow, etc.) and style (lofi, rock, pop, etc.), returning a random track on each call for unlimited playback.

Main functions of AudioLib

  • Single API audio callA POST /v1/audio An endpoint that takes a music library name as input can return a playable audio URL, requiring no complex integration.
  • A vast library of carefully selected music.Covering over 100,000 original songs, divided into dozens of standard music libraries based on scene and style, such as... audio.focus,audio.sleep,audio.rock,audio.lofi wait.
  • Random carousel mechanismEach time it is called, it randomly selects one song from the specified music library, and naturally supports infinite loop and continuous playback to avoid repetition.
  • Bearer Token AuthenticationAPI Key alp_ It begins with standard HTTP authentication, supporting calls from any language such as cURL, JavaScript, and Python.
  • Usage statistics and logsThe Dashboard provides request logs and call count statistics, facilitating monitoring and billing management.
  • Zero copyright riskAll music is created and generated independently by the team, so developers don't need to worry about copyright negotiations or licensing compliance issues.

How to use AudioLib

  • Register and create an API KeyVisit the AudioLib website https://www.audiolib.ai/, register an account, and generate an API Key in the Dashboard.
  • Select Music Library: Go to the Libraries page and browse the music library by function or style (e.g., audio.focus,audio.ambientListen to the product and confirm that it matches the product's style.
  • Initiate API callSend an HTTP POST request to the product. https://api.audiolib.ai/v1/audioHeader Authorization: Bearer alp_xxxxBody input { "library": "audio.xxx" }Analyze the response url The field can be played directly.

AudioLib's core advantages

  • Minimal integration, access with just one line of codeIt requires only a single POST API call, without the need for SDK, player, backend system, or music library management, allowing you to access music just like you would access a large model.
  • Zero copyright risk, all original music library100,000+ songs are created and open-sourced by the team, so developers don't need to worry about copyright negotiations or licensing.
  • Contextualized curated music libraryIt is divided into dozens of standard music libraries based on function (focus, sleep, workflow) and style (lofi, rock, pop), with hundreds to thousands of songs in each library. Each time it is called, it will play randomly in rotation and naturally supports unlimited playback.
  • CDN direct link instant playbackThe API directly returns the CDN audio URL with time limits, allowing the client to play it natively without going through a server, resulting in extremely low latency.
