There's a bit lag when using audio tags. Check out the demo and click the play sound button, and notice the delay before hearing the sound. This doesn't occur in chrome or firefox. I've had several users report this, though it's not universal. It makes games made with the engine really unplayable for a lot of people in safari. There are workarounds for audio latency in general using webkitAudioContext - but because the engine generates sound URLs, and because I can't find any way of populating an audiobuffer without using XMLHttpRequest (I've asked around quite a bit and can't find any alternatives), and because safari treats data URIs as being cross-origin requests, I'm stumped. I thought that using cloneNode().Play() might have been a problem, but even just playing a single audio file once gives this problem (try remove cloneNode() from the example html file). 229202 2014-04-12 05:37:36 -0700 2014-04-12 05:37:36 -0700 Click the button, notice latency, clicking lots of times doesn't help. audio_latency_bug.html text/html 1598 analytic PGh0bWw+CjxoZWFkPgo8c2NyaXB0PgoJdmFyIHNuZGZpbGUgPSAiZGF0YTphdWRpby93YXY7YmFz ZTY0LFVrbEdSdEVEQUFCWFFWWkZabTEwSUJBQUFBQUJBQUVBaUJVQUFJZ1ZBQUFCQUFnQVpHRjBZ YTBEQUFES3lNWnpQa0JYdXJpMVprNVJjS3FucFdKYlczNmtwSjliVzF1S282T1VYRnhjbGFPamlG eGNYS0NqbzMxY1hHU2pvNkp5WEYxdm9xS2lhRjFkZXFLaW9sMWRYWVdpb3BkZFhWMlBvYUdNWGw1 ZW1xR2hnbDVlWWFHaG9YZGVYbXlob2FGdFhsNTJvS0NnWTE5ZmdhQ2dtbDlmWDR1Z29KQmZYMStW b0tDRlgxOWducCtmZTJCZ2FaK2ZuM0pnWUhPZm41OW9ZR0I5bjU2ZFlHRmhocDZlazJGaFlaQ2Vu b2xoWVdHWm5wNS9ZV0ZtbnAyZGRtSmljSjJkblcxaVlubWRuWjFrWW1LQ25aMlZZbUpqaTV5Y2pH TmpZNVNjbklOalkyU2NuSng2WTJOdG5KeWJjV1JrZHB1Ym0ybGtaSCtibTVoa1pHU0htNXVQWkdS a2tKdWFobVZsWlppYW1uNWxaV3VhbXBwMlpXVnptcHFhYm1WbGU1bVptV1ptWm9TWm1aRm1abWFM bVptSlptWm1rNW1aZ1dabmFaaVltSGxuWjNHWW1KaHlaMmQ1bUppWWFtZG5nSmlZazJob2FJaVhs NHRvYUdpUGw1ZUVhR2hvbHBlWGZXaG9iNWVXbG5WcGFYYVdscFp2YVdsOWxwYVVhV2xwaEphV2pX bHBhb3VWbFlacWFtcVNsWlYvYW1wdGxaV1ZlV3BxZEpXVmxYSnJhM3VVbEpSc2EydUJsSlNQYTJ0 cmlKU1VpR3RyYTQ2VWs0SnNiR3lUazVOOGJHeHprNU9UZG14c2VaT1RrM0JzYkgrU2twQnRiVzJG a3BLS2JXMXRpcEtTaEcxdGJaQ1NrbjV0Ym5HUmtaRjVibTUza1pHUmMyNXVmWkdSa1c1dWJvS1Jr WXR2YjIrSGtKQ0diMjl2akpDUWdXOXZjWkNRa0h0dmIzYVFqNDkzY0hCN2o0K1BjbkJ3Z0krUGpI QndjSVdQajRkd2NIR0pqbzZDY1hGeGpvNk9mbkZ4ZFk2T2pubHhjWHFPam81MWNuSitqWTJNY25K eWdvMk5pSEp5Y29lTmpZUnljbktMall4L2MzTjFqSXlNZkhOemVZeU1qSGh6YzMyTWpJeDBjM09C aTR1SWRIUjBoSXVMaFhSMGRJaUxpNEYwZEhXTGk0dDlkSFY0aW9xS2VuVjFmSXFLaW5kMWRYK0tp b2gxZFhXQ2lvcUZkbloyaFltSmduWjJkb2lKaVg5MmRuaUppWWw4ZG5aN2lZaUllWGQzZm9pSWlI ZDNkNEdJaUlWM2QzZURpSWlEZDNkNGhvZUhnSGg0ZVllSGgzNTRlSHVIaDRkN2VIaDloNGVIZVhs NWdJYUdoWGw1ZVlLR2hvTjVlWG1FaG9hQmVYbDVoWWFGZjNwNmU0V0ZoWDE2ZW4yRmhZVjdlbnAv aFlXRWVucDZnWVNFZzN0N2U0S0VoSUY3ZTN1RGhJU0FlM3Q4aElTRWZudDhmWU9EZzMxOGZIK0Rn NE44Zkh5QWc0T0NmSHg4Z1lPRGdYMTlmWUtDZ29COWZYMkNnb0ovZlgxK2dvS0NmbjE5ZjRHQmdY NStmbitCZ1lGK2ZuNkFnWUdBZm41K2dJR0JnSDUrZjRDQWdIOS9mMytBZ0lCL2YzOS9nSUNBZjM5 L2Y0Q0FnQT09IjsKCnZhcglzZnggPSBuZXcgQXVkaW8oKTsKc2Z4LnNyYyA9IHNuZGZpbGU7CQoK ZnVuY3Rpb24gcGxheVNlZWQoc2VlZCkgewogICAgc2Z4LmNsb25lTm9kZSgpLnBsYXkoKTsKfQo8 L3NjcmlwdD4KPC9oZWFkPgo8Ym9keT4KPGZvcm0+PGlucHV0IHR5cGU9ImJ1dHRvbiIgdmFsdWU9 IlBsYXkgU291bmQiIG9uY2xpY2s9InBsYXlTZWVkKCk7Ij48L2Zvcm0+Cgo8L2JvZHk+CjwvaHRt bD4=
