Audiotool Online Music Studio

Audiotool is a free browser-based music production studio that allows users to create, collaborate on, and publish electronic music entirely online. Founded in 2008 by Christian Sander and Alexander Günstner in Stuttgart, Germany, Audiotool was one of the first platforms to bring professional-grade music production tools to the web browser using Flash and later Web Audio API. The platform has attracted over 2 million registered users and hosts a vast library of user-created tracks. Key features: modular interface: the studio uses a visual, cable-based modular synthesizer approach where users drag devices (drum machines, synthesizers, effect pedals) onto a virtual desktop and connect them with cables. This mimics the experience of working with physical hardware. Built-in devices: includes classic drum machines (emulating Roland TR-808, TR-909), synthesizers (with oscillators, filters, and envelopes), samplers, and effect pedals (reverb, delay, distortion, chorus, compression, equalization). Pattern sequencer: a piano-roll style sequencer for programming MIDI notes, with support for multiple patterns per track and per-note automation. Sample library: access to thousands of user-uploaded audio samples and presets. Collaboration: real-time multiplayer sessions where multiple users can work on the same track simultaneously from different locations. Publishing: finished tracks can be published directly to the community platform, where other users can listen, like, comment, and remix. Each published track has a dedicated page with an embeddable player. Community: charts, competitions, and discovery features for finding new music and connecting with other producers. Education: tutorial resources for learning music production. Runs in any modern browser. JavaScript/Web Audio API. Proprietary, free.
