This is lovely. It seems to bug out in Firefox 25 when I switch away from the tab it's on - any debugging info that would be useful?

  This is probably because Firefox (and Chrome) clamps the setTimeout interval of background tabs to 1 second to improve performance.

    Huh? Is that new? Can I turn it off?

      It was introduced in Firefox 5 [1]. You can change it in about:config by tweaking "dom.min_background_timeout_value" to a lower value (in milliseconds). [1]: https://bugzilla.mozilla.org/show_bug.cgi?id=633421 https://bugzilla.mozilla.org/show_bug.cgi?id=633421

      I believe window.requestAnimationFrame is preferred over setInterval, and doesn't get limited as such. https://developer.mozilla.org/en-US/docs/Web/API/window.requestAnimationFrame https://developer.mozilla.org/en-US/docs/Web/API/window.requ...

        Actually requestAnimationFrame is limited more (possibly even entirely paused) as it assumes that if the tab isn't visible, no animation needs to be requested

  Sorry, but this is an issue of the browsers.

  He should update it to work with Firefox. Since Firefox 25 they have changed to Web Audio.

This is awesome. Ring modulation and samples seem to be missing? I've been humming Hubbard's theme to "Nemesis the Warlock" this past week so I pulled that up and its ominous drones were just... off. I also decided to try Crowther's theme to "Zig Zag" to see how it would cope with the torture test of a play routine running more than once a frame; that got pretty mutilated too. But when it works, it's pretty damn awesome!

  Thanks. Yes, some features are indeed missing. But most of the tunes are working fine. I am thinking to emscript reSID or something.

would probably be awesome (love SID tunes), but I get noting in latest firefox beta, nothing in latest chrome, nothing in latest opera, and nothing in internet explorer 11. my guess there's something wrong.
- s-macke 13y ago
  It works under Firefox 25 and Chrome. Should also work with Firefox 23 and 24. The others I have not tested. But some of them lack audio support. And I would not try Firefox beta. They have changed the audio API and probably fixing bugs right now. I had problems to get it running under Firefox 25 after they implemented the web audio API.

  A lot of songs are not working. Try only the button "Slightly Random Choice.sid" They all work.
  - tech-no-logical 13y ago
    that was it. the rest of the menu gives me nothing, the random button works fine :) great stuff.

  Works fin-ish in Chrome Version 31.0.1650.48 m. but if I put it into background tab it sounds like a broken record.
