What else can we do with the Web Audio API?

Of course the Web Audio API is meant for synthesizing and processing audio data. It is tailored for that use case. But at least in our digital world audio data is just a series of numbers, which are typically somewhere between +1 and -1. So why can't we use the Web Audio API for general computations?

Almost a year ago I had the pleasure to give a talk at the Web Audio Conference in Atlanta. The conference featured a lot of great talks, which I really appreciated as an attendee. However, as a speaker it was tough to reduce my own talk until it was short enough to fit into the schedule. I had the feeling that I had to rush through my slides. Since then I planned to write down my findings in a more detailed way, but I never got around to it. Luckily I was asked to repeat my talk at our local Web Audio Meetup here in

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Native app performance metrics

This is a draft list of what we're thinking about measuring in Etsy's native apps.

Currently we're looking at how to measure these things with Espresso and Kif (or if each metric is even possible to measure in an automated way). We'd like to build internal dashboards and alerts around regressions in these metrics using automated tests. In the future, we'll want to measure most of these things with RUM too.

Overall app metrics

App launch time - how long does it take between tapping the icon and being able to interact with the app?
Time to complete critical flows - using automated testing, how long does it take a user to finish the checkout flow, etc.?
Battery usage, including radio usage and GPS usage
Peak memory allocation
