Seems good at least just clicking to play stuff … though it didn't work in Safari. Works fine in Chrome and Firefox on the same (OS X) system. Safari version 6.1.1 (7537.73.11)

You need at least Firefox 25 for web audio. However I thought older versions would be supported through the older audio api. Will check later.

Playback works fine for me in Chrome. The HVSC player doesn't handle non-ASCII characters though. Dunno if it's because of the font or if it uses the wrong character encoding.

When I opened the inspector after the page had loaded, this was in the console:

Code:

[Error] ExitStatus: Program terminated with exit(0)
	exit (playsid.js, line 9402)
	__exit (playsid.js, line 4139)
	_exit (playsid.js, line 4141)
	eK (playsid.js, line 7812)
	ccallFunc (playsid.js, line 553)
	ccall (playsid.js, line 512)
	playsid_play (playsid.js, line 9442)
	sid_play (playsid.html, line 13)
	onload (playsid.html, line 30)

As a web dev, I have no idea what to make of that … unless there's some code that defines an ExitStatus class subclassing Error that was thrown with that message.

When I reloaded the page I got something more sensible in the console:

Code:

[Error] TypeError: 'undefined' is not a function (evaluating 'this.hide()')
	close (content_start_0.js, line 1)

That doesn't copy what I think is the character number, so it says 1601 if that helps any.

sasq: doesn't work for me, safari 7.0.1 / osx 10.9.

There's a nice big clue in the console, since this is printed in big red letters:

Quote:

[Error] Failed to load resource: the server responded with a status of 404 (Not Found) (favicon.ico, line 0)

And just above that, some less useful stuff about Web Audio not being available:

From what I remember, safari does support web audio but there are incompatibilities.

Yes Safari should be supported. The relevant code that throws the exception in emscripten-SDL is this:

Code:


if (!SDL.audioContext) {
          if (typeof(AudioContext) === 'function') {
            SDL.audioContext = new AudioContext();
          } else if (typeof(webkitAudioContext) === 'function') {
            SDL.audioContext = new webkitAudioContext();
          } else {
            throw 'Web Audio API is not available!';
          }
 }

so even though it's supposed to be supported it fails to create an AudioContext...

@hoover: Tried in Firefox 23.0.1 and it works here (Ubuntu).
