Hello guys, Hope you're all having a nice summer! (Get well, Al!) I feel a bit like a broken record for going on with this again, but bare with me. I think there's an important point we need to think about when we're designing this API. If we do this wrong, so many people are going to be really mad at us. Audio APIs have the problem that if you can't do much with the core, you can't do much with the rest either. That's why I've been touting "freedom, freedom..." for some time now. At first, I think it's of utmost importance that we stop premature optimization with this API, it is going to shoot us in our backs, there's no question of it. So next time we're suggesting taking away a freedom – such as the programmer being able to decide the sample rate – think of the justifications. If it's performance, think again, not good enough, not future-proof. Computers are going to get faster, that's inevitable. (Once the graphene sheets hit the market, the processing power of consumer computers is forecast to be 300-3000x the current) Twenty years from now, if people are still using this API, they won't be damning it because it isn't fast enough, but because they can't do what they want with it. I'm not saying we shouldn't keep performance in mind, it's an important thing, but I think no compromises should be made in the name of performance. Same goes a bit for implementation difficulty, but of course, some of us are going to be the ones writing the implementations as well, so I understand you guys disagreeing on such points. This means I have nothing against the idea of pre-defined standard purpose processing nodes, to serve as the basis for games, etc, and to provide extra performance, they're not hurting any freedoms I'm seeing. However, Chris mentioned earlier something about adding a reasonable maximum value for the sample rate and unless there's a good reason for it, I'm not convinced that such a thing should exist. So, what I'm saying here is... We're making specs, and we've been given relatively free hands at that, making us a very unique standards working group indeed (wouldn't you agree, Doug? ;) ), so let's be idealistic! Let's make this thing future-proof, and think more of the spec than the implementation. Like Philip said on Twitter "we only get one chance at designing this API". Cheers! Jussi P.S. Doug, Al, what's happening with adding Amos Wenger (the guy behind JSMad) as an invited expert to the group?
