Audiopia is a peer-to-peer music streaming platform built with modern Web Standards technologies (such as WebSockets and WebRTC) and APIs (MediaSource API, Web Audio API).

Your songs are not stored anywhere but on your computer. Only meta-informations (title, album, artist, year, etc.) are available online. When you listen to a song, you stream the audio content directly from an other user.

Streaming is performed by a combination of client-server access and P2P protocol between Web users. This is done in an adaptive and transparent way in order to reduce server bandwidth costs while ensuring low latency and smooth playback for users.

Audiopia is entirely built with Web Standards. For you this means no plugins or installation. You only need one of the supported browsers listed below.

Start your browser, type the URL and you are ready to go.

You don't have to register to use Audiopia. Go to audiopia.io and start listening to the music you love.

In fact, Audiopia is fully anonymous, our service is about music, not users.
Note: We do not collect or store any user specific information.

We built our platform with Meteor (a complete open source framework for building reactive web and mobile apps in pure JavaScript) and PeerJS (a Javascript library which provides a complete, configurable, and easy-to-use peer-to-peer connection API).

Each time a user accesses audiopia.io, he gets a new generated id from the server. This id is used to identify each user as the owner of each song he makes available. The id is also used to create peer-to-peer data or media stream connections between users.

When the user imports new songs, the browser analyses each file and parses its meta-informations (title, album, artist, year, etc.). For each valid audio file loaded by the user, a new document is inserted to the server's database:

{"title": "Come closer", "artist: "Guts", ..., "mime": "audio/m4a", "owner": "gd8FMwsTS4T4ejytg"}

The server implements a fully-reactive NoSQL database (MongoDB) to keep track of available songs. It's data is instantly reflected to every connected user (see Meteor for more details). When a user exists, the server automatically remove all of his songs on the database.

To stream a song, the browser uses the owner's identifier to create a peer-to-peer media connection (PeerJS) and stream the audio file (see WebRTC, Web Audio API and MediaSource API).

Check the code for more details.

We use a set of open standards technologies and apis which are not supported by all browsers. Before you start, check if your browser supports following requirements:

• WebSockets
• WebRTC
• Web Audio API
• MediaSource API
• Filesystem API (optional)
• IndexedDB (optional)
