it sounds your processor can't keep up with your sound buffer. you can start Google chrome up with --audio-buffer-size=2048 to increase it All audio technologies have buffer issues, it's a pretty basic problem. it's not unique to web audio.

Nope, that's not it, makes no difference. Saying that all audio technologies have issues is a dodge. Technology is hard, software is about dealing with problems not about passing the buck and saying "sorry it sucks, it's hard and I gave up". Computer audio isn't exactly rocket science, tons of products get it right, browser makers just can't be bothered to invest in it.

> Computer audio isn't exactly rocket science

Ironic, in the context of this article.

> it sounds your processor can't keep up with your sound buffer Is this 1994? We've been playing fancy, high definition, multi-channel audio on our computers for decades now, and it's been ages since I've seen it impact the CPU. > All audio technologies have buffer issues, it's a pretty basic problem. it's not unique to web audio. I would say that in 2015, for most people it is unique to web audio. Generally speaking…

This is because "fancy, high definition, multi-channel audio" has >40ms latency, so you cannot compare it with Web Audio, which is meant to be real time like in digital music settings, where often <8ms is required. You clearly do not understand the problem you are claiming to be simple.

How can web audio be realtime when it doesn't have a realtime scheduler? That may be driving this problem: the browser's javascript engine not being scheduled in time by the underlying operating system.

Is there a download available for offline listening?

Hello, post author here, were you thinking about downloading the NASA sound clip or the web audio recreation?

Either but originally I meant the recreation.

Ok, no problem, I've uploaded both audio files to my SoundCloud account (https://soundcloud.com/outputchannel) and you can download them by clicking the download button beneath the waveform display.

Pretty neat! I've heard those beeps a lot but never knew what they were for. Also, is it me, or do the sounds in the example recording sound the same? (frequency-wise?)

Thanks! Listening to the recording, I'm reasonably sure I can distinguish the two different frequencies, but there's no denying they sound very similar. They're so close there's less than a semitone between them.
