JSFoo is India’s premier JavaScript conference. This year is the fifth edition.
The theme for the 2015 edition is the future of JavaScript.
We are looking for talks and workshops from academics and practitioners who are at the cutting edge of developments in JavaScript.
We want to hear all about:
- Advances in browser JavaScript
- JavaScript in hardware
- Functional JavaScript
- Cutting edge developments, including original work
- ES6
Editorial panel
- Santosh Rajan, founder Geekskool
- Shwetank Dixit, Extensions Program Manager and Web Evangelist, Opera Software
- Sindhu S, Recurse Center alumni
- Zainab Bawa, editorial coordinator, co-founder at HasGeek
Commitment to Open Source
HasGeek believes in open source as the binding force of our community. If you are describing a codebase for developers to work with, we’d like it to be available under a permissive open source license. If your software is commercially licensed or available under a combination of commercial and restrictive open source licenses (such as the various forms of the GPL), please consider picking up a sponsorship. We recognize that there are valid reasons for commercial licensing, but ask that you support us in return for giving you an audience. Your session will be marked on the schedule as a sponsored session.
Workshops
If you are interested in conducting a hands-on session on any of the topics falling under the themes described above, please submit a proposal under the workshops section. We also need you to tell us about your past experience in teaching and/or conducting workshops.
BOF sessions
If you are interested in doing an unconference during the breakout sessions, propose a topic which will be of interest to the community.
Important dates:
Deadline for submitting proposals: 31 July 2015
Conference dates: 18-19 September
Workshops: 15, 16, 17 and 20 September

Orchestrating the Web Audio API
Submitted Jun 20, 2015
Section:
Full talk
Technical level:
Advanced
Understand the basics of low latency audio performance within the browser using the graph-based Web Audio API. Understand intricacies of orchestrating WAA’s graphs to build sophisticated composable sound models using the timing and graph abstractions in the Steller library.
Outline
The evergreen browsers today ship with a powerful low latency audio generation and processing API - the Web Audio API - that opens up new possibilities for immersive browser-based games, advanced audio/music applications, interactive simulations for children and such. The purpose of this talk is to give a glimpse of this API, dive into its design and provide tips on effective usage and relevant abstractions, focusing on Steller - a small library developed by the author for coordinating audio and visuals.
Tentative flow: Ways of “organizing sound” - a lightning tour of computer music. A brief history of in-browser audio. Low latency audio generation and processing. The Web Audio API and its underlying graph model. Intro to some commonly used node types. Importance of sample accurate timing. Orchestrating lifetimes of ephemeral “one shot” nodes. Steller’s GraphNode and declarative scheduler abstractions. Issues with precise coordination of audio and visuals - case: a metronome app. Advanced: Signal processing in Javascript using the JS audio node.
Requirements
This could be in a workshop format too. Participants would need a computer with the latest version of Chrome installed, a decent pair of headphones or in-built speakers for ... making noise :)
Speaker bio
Currently heads engineering at Pramati Technologies, Chennai. Has worked with the Web Audio API since its early days and used it heavily for research into gamaka synthesis for Carnatic music.
