About the first and third points, it would be great if you can send detailed feedback to this mailinglist: http://lists.w3.org/Archives/Public/public-audio/. Doing that would give us a chance to discuss these issues and fix the spec if possible. About the second point, that's not accurate. All audio processing in a conforming Web Audio implementation happens on a background thread reserved for audio processing, which does not need to wait for things happening on the main thread (including GC pauses.) In practice, Gecko's processing model uses message passing between the audio thread and the main Javascript thread. WebKit and Blink use locks to synchronize the two threads some of the times, but the locking is minimal and it should not have a huge impact on performance. About the testing issue, the working group has started to work on i

t recently, and you can see the beginning of the work here: https://github.com/w3c/web-platform-tests/tree/master/webaud.... We're planning to integrate the regression tests from both Mozilla and WebKit into the test suite for the spec (http://mxr.mozilla.org/mozilla-central/source/content/media/... and http://trac.webkit.org/browser/trunk/LayoutTests/webaudio) into the test suite. And of course, contributions for more tests are always welcome.

This is not a comment to you in particular, but when authors find bugs in browsers there are several things that they can so to ensure that the bug is fixed as quickly as possible: 1. Verify that the bug occurs in the latest available (possibly unstable/nightly) build. 2. Submit the bug to the relevant browser/engine bug tracking system (see below). If you aren't confident about how to write a good bug report, read [1] first. 3. Write a testcase. If at all possible this should be minimal (i.e. not using the whole of jQuery/Angular/whatever) and should certainly be clear (e.g. no minimised code unless it is actually needed to reproduce the issue). 4. If the bug is a conformance bug rather than a QoI issue, submit your testcase to the W3C [2] so that it can be incorporated into the standard testsuite and automatically run by all browser ven

dors. To do this the test needs to be written in a standard format [3] and submitted using the process at [4]. At the moment the documentation is a bit sucky, but there is a big revamp in the works [5], so that should improve in the near future. That last one may sound like a lot of effort, but testing is the only way that we will end up with a web platform that is both technologically competitive and open both in spirit and in practice i.e. with multiple interoperable implementations. People put a huge amount of time into working around, and complaining about, cross browser issues. Devoting a small fraction of that time to submitting regression tests instead would dramatically decrease the number of problems in the future. For example submitting a test for canvas clipping both makes it likely that IE will be fixed in the near future, and also ensures that it won't then just regress again one version later. It seems that it would be in the self-interest of big projects like jQuery to commit to creating a test for each time they have to work around some browser bug, so they can expediate fixing the issue, track which browser versions have the bug, and remove the workaround — and thus reduce their code complexity — as soon as the test passes in all the browsers they are targeting. However this is not just something that matters to big projects. If you have run across a bug that is making it difficult to implement something, you are likely the best person in the world to write a testcase for that issue. If you are trying to submit bug reports and tests and need help, please ask on #whatwg on Freenode irc or #testing on irc.w3.org [6].
