The 2nd Web Audio Conference (WAC) will be held April 4-6, 2016 at Georgia Tech in Atlanta. WAC is an international conference dedicated to web audio technologies and applications. The conference welcomes web developers, music technologists, computer musicians, application designers, researchers, and people involved in web standards. The conference addresses research, development, design, and standards concerned with emerging audio-related web technologies such as Web Audio API, Web RTC, WebSockets and Javascript. It is open to industry engineers, R&D scientists, academic researchers, artists, and students. The first Web Audio Conference was held in January 2015 at IRCAM and Mozilla in Paris, France. The Internet has become much more than a simple storage and delivery network for audio files, as modern web browsers on desktop and mobile devices bring new user experiences and interaction opportunities. New and emerging web technologies and standards now allow applications to create and manipulate sound in real-time at near-native speeds, enabling the creation of a new generation of web-based applications that mimic the capabilities of desktop software while leveraging unique opportunities afforded by the web in areas such as social collaboration, user experience, cloud computing, and portability. The Web Audio Conference focuses on innovative work by artists, researchers, and engineers in industry and academia, highlighting new standards, tools, APIs, and practices as well as innovative web audio applications for musical performance, education, research, collaboration, and production. Contributions to the second edition of the Web Audio Conference are encouraged in the following areas: - Web Audio API, Web MIDI, Web RTC, and other existing or emerging web standards for audio and music - Development tools, practices, and strategies of web audio applications - Innovative audio and music based web applications - Client-side audio processing (real-time or non real-time) - Audio data and metadata formats and network delivery - Server-side audio processing and client access - Client-side audio engine and audio rendering - Frameworks for audio synthesis, processing, and transformation - Web-based audio visualization and/or sonification - Multimedia integration - Web-based live coding environments for music - Web standards and use of standards within audio based web projects - Hardware and tangible interfaces in web applications - Codecs and standards for remote audio transmission - Any other innovative work related to web audio that does not fall into the above categories We welcome submissions in the following tracks: paper, poster, demo, performance, and artwork. All submissions will be single-blind peer reviewed. The conference proceedings, which will include both papers (for papers and posters) and abstracts (for demos, performances, and artworks), will be published online in SmartTech, Georgia Tech’s archival open-access repository. *Papers*: Submit a 4-6 page paper to be given as an oral presentation. *Talks*: Submit an abstract to be given as an oral presentation. *Posters*: Submit a 2-4 page paper to be presented at a poster session. *Demos*: Submit an abstract to be presented at a hands-on demo session. Demo submissions should include a title, a one-paragraph abstract and a complete list of technical requirements (including anything expected to be provided by the conference organizers). *Performances*: Submit a performance making creative use of web-based audio applications. Performances can include elements such as audience device participation, web-based interfaces, WebMIDI, WebSockets, and/or other imaginative approaches to web technology. Submissions must include a title, a one-paragraph abstract of the performance, a link to video documentation of the work, a complete list of technical requirements (including anything expected to be provided by conference organizers), and names and one-paragraph biographies of all musicians involved in the performance. *Artworks*: Submit a sonic web artwork or interactive application which makes significant use of web audio standards such as Web Audio API or WebMIDI in conjunction with other technologies such as HTML5 graphics, WebGL, and/or interactivity. Works must be suitable for presentation on a computer kiosk with headphones. They will be featured at the conference venue throughout the conference and on the conference web site. Submissions must include a title, one-paragraph abstract of the work, a link to access the work, and names and one-paragraph biographies of the author(s). *Tutorials*: If you are interested in running a tutorial session at the conference, please contact the organizers directly (webaudio at gatech dot edu). *IMPORTANT DATES* - October 1, 2015: submission deadline - December 1, 2015: author notification - March 1, 2016: camera-ready papers and abstracts due - April 4-6, 2016: conference At least one author of each accepted submission must register for and attend the conference in order to present their work. *SUBMISSION TEMPLATES AND SUBMISSION SYSTEM* Submission templates are available on the conference web site at http://webaudio.gatech.edu/node/22 The submission system is open at https://cmt.research.microsoft.com/WAC2016/
