Ugh, why do people do that to begin with? :( I've had Web Audio for a while since I'm on the Aurora channel, and there's so many demos that refuse to work for no reason. I try to do my part by submitting pull requests that fix it, when possible, but most of those pull requests have been sitting ignored for months. Clearly more people need to be educated that user-agent sniffing = bad.
Sorry, you're wrong. I hate to be rude about it, but I'm really getting tired of people, who don't know any better, acting like feature detection is always the way to go. Feature detection simply doesn't work it many cases, and there's no alternative. Especially with new stuff like audio, sometimes function calls need to be called in different orders, have subtly different behaviors, etc., and user-agent sniffing is…
Assume good faith.
