People really love messing about with audio.
Notice that the process of creating all this cool functionality didn’t come about from a W3C spec. Similarly, the Advanced Audio APIs were not the result of a W3C think-tank, but from two competing visions of what an advanced audio API should look like. Now it looks like the Web Audio API will be implemented in Safari as well as Chrome.
Once you create compelling functionality, developers will immediately start to use it. It may be experimental but developers will start to rely on it to make cool stuff. Cutting edge technology is seductive like that. I’m surer than sure that the Web Audio API has been well researched and has taken much inspiration from tried and tested APIs that exist outwith of our lovely browser based world (Apple’s Core Audio Frameworks, I believe), but I’m not convinced that you can really tell what web developers need or want until you give them something to play with.
*Neither Firefox or Opera support MP3 natively due to patent concerns.
I’m not saying Mozilla’s Audio Data API is perfect, there are issues with audio using the same thread as the UI and synch issues with multiple streams. However this is being addressed in the MediaStreams Processing proposal and it’s worth taking a look at it, even if it’s just for an insight into what future implementations could look like.
Strong community — Web developers have a huge active and open community to draw from.
Lower barrier to entry — The barrier of participation once something is put on something like github is virtually zero.
Ok, so bear with me here, and this is more of a question than a proposal – What if we separate concerns between browser makers and web developers when it comes to creating standards? Browser makers could concentrate on security, privacy, performance and exposing low level API’s in such a way that web developers can start to build libraries and APIs in the fluid, dynamic, iterative and extremely reactive manner that the web as a media allows. Once these libraries reach an acceptable level of adoption, browser makers can get together and decide which of these features they want to adopt based on tried and tested use cases, and yes make it a standard and build it into the browser. Wouldn’t we move forward more quickly that way? And as a bonus, no browser would be left behind as we’d be building the polyfills along the way.
In short, what I’m saying is that if the standard bodies put their energy into defining low level APIs, the high level APIs will look after themselves, or rather the community will look after them. After all it seems that the W3C themselves want a more community based approach to standards and besides we all know that bottom-up trumps top-down, right?
Outside my flat is an open space that the local council didn’t quite know what to do with, I’m sure they considered adding basket-ball hoops, concrete tables, a kid’s playground and all kinds of things. As it turned out they created a decent flat surface and pretty much left it as that. The users of this space, mostly children, decided this was a perfect space for playing soccer and improvised the space to include a hand drawn goal and pitch markings. If the council really wanted to make something permanent, they could take inspiration from this and create real goals and solid pitch markings.
It’s probably too late to change the Webkit implementation of the Web Audio API significantly, but I would strongly urge the developers of it to include a more comprehensive low level API in future releases. What’s the worst that could happen?
