I'm seeing the same issue. Also:

Uncaught abort() at Error
    at Error (native)
    at qd (http://localhost:5000/js/libmp3lame.min.js:223:143)

take a look at my pull request, it fixes it amongst other things

@kobigurk could you kindly provide a compiled version of your fork? According to brew page ( Homebrew/legacy-homebrew#29988 ) emscripten formula still broken on yosemite and i can't get it to work by manually installing it.

Thanks in advance
Chris

Hi Chris,

Take a look at my fork, it has both the compiled version and a minified one.
https://github.com/kobigurk/libmp3lame-js

I already checked your dist folder but it looks like they are still the same as the original version. Or I'm wrong?

You're correct, I mistakenly didn't commit the new compiled files. They're pushed now, thanks, take a look.

Awesome! Thanks, pulled and now it works properly with recording longer than 1 minute! Really thanks Kobi I owe you a beer!!

No problem, have fun :-)

Yes, the prebuilt minified version is bad. I am no emscripten expert, but I got it working by "exporting" all wrapped c functions like this: Module["_get_lame_version"] = _get_lame_version; etc and then ran it through closure myself. Got the code size down to 512kb which isn't too shabby.

@malstrom72 Can you share the minified version?
