Intent to Ship: Web Audio

[Ehsan Akhgari]

We have been working on implementing the Web Audio API for quite a while
now, and we've had an experimental implementation on Nightly and Aurora for
several cycles now.

We're getting close to a stage where we feel that we're ready to ship this
API by default.  There is still some implementation work to be finished,
and there are a few spec issues to be resolved, but we're relatively
confident that we can address all of these issues by the time we release
Firefox 25, therefore I would like to announce the intent to ship this API.

There is some risk involved from the spec level discussions which we're
currently having in that the discussions may not finish in a timely
manner.  In that case, we will delay shipping this API until we reach a
resolution on the W3C Audio Working Group, and I will follow-up to the list.

Please let me know if you have any questions.

Cheers,

What led you to feel comfortable with shipping? Is it based on interoperability 
with some significant content and another UA? Is there a test suite?

Ship means no longer behind a flag, right?

I'm admittedly a little bit concerned - if we ship, it's a strong signals to 
the W3C Web Audio WG we are happy with the API that is spec'ed as is (that may 
be true - it might be the best that the group can do and it might very well be 
a spec from which interoperable implementations can be created). My personal 
opinion about the spec is that it could be improved (lots of stuff seemed 
underspecified, etc. when I tried to read it a few months ago - but maybe it's 
better now) - if it mostly works across at least 2 browsers, then I guess it's 
time to ship.

We will probably be the first and only spec conformant implementation 
when we ship (the WebKit and Blink implementation does not conform to 
more recent spec changes.)


The reason that I feel comfortable shipping this is that we're getting 
close to the spec being considered stable, and I believe that we can 
just land any future fixes based on further spec changes after we ship.



There is still some implementation work to be finished,
and there are a few spec issues to be resolved, but we're relatively

Yes, that's correct.

(Technically, it means flipping the default value of the flag to true. 
We will still preserve the flag as a disaster recovery tool.)



There is some risk involved from the spec level discussions which we're
currently having in that the discussions may not finish in a timely
manner. In that case, we will delay shipping this API until we reach a
resolution on the W3C Audio Working Group, and I will follow-up to the list.

I have previously indicated our intent to ship to the working group for 
Firefox 24, but that slipped.  I need to update the working group on the 
new plans.


Shipping Web Audio doesn't mean that we're necessarily happy with all 
parts of the spec, but we're making trade-offs between having a good API 
that everybody agrees on, and shipping code which works with some of the 
existing content.  We have heavily discussed these issues in the working 
group.

Thanks for the clarifications.

I'm not at all comfortable with adding data races to the platform. Or
did we solve them in some manner?

We have not implemented the racy version of the API in Gecko, and we're 
planning to work with the Audio Working Group and go through with the 
W3C process governing it to make sure that the group comes to a 
conclusion which does not expose data races to the Web platform.  This 
is basically what I meant when I talked about remaining spec issues to 
be resolved.


If the working group finally comes to the conclusion that the spec 
should not be changed to fix this, then we will need to have further 
discussion on what to do, but until then, rest assured that I do share 
your concern there.  :-)
