I have an application for Google Chrome and I want it to emit a sound every time a notification is created, but in my tests I was not very successful =p

I don’t know if it’s some permission or if there really isn’t any way I can do it.

Do you know any way? (Detail: I wanted the js file in the background to do this)

javascript google-chrome

  • What did you try? I imagine injecting an element <audio> via js should work.

  • i tried to use an audio tag and js: new audio(''). play; none of the 2 worked =/

  • And what format does the audio file have? I think it needs to be ogg.

  • Hm, I think I made a mistake, check out the format table: https://developer.mozilla.org/en-US/docs/HTML/Supported_media_formats

  • this link has no table =p

    There at the end has a compatibility table, by file format and browser.

  • Wow, that weird, now it worked =O Thanks o/

    Cool, I was already going to do a test, saved me work :) Now I’ll give you work: can you post the solution as a response to help future visitors? Thank you!

Already tried using the Web Audio API?

 var context = new webkitAudioContext();
 var oscillator = context.createOscillator();
 oscillator.connect(context.destination);
 oscillator.frequency.value = 780; //frequencia do som, altere pra mudar o som que será emitido
 oscillator.start(0);
 oscillator.stop(context.currentTime + 0.5)//duração do som;

If you use the API take into account that the "Oscillator" is destroyed after use, for each sound you must create a new.

  • I’ll try Luke :) It’s kind of hard to find a good note =O
