Does web audio oscillator type not work in Chrome, Firefox?

I seem to just get sine waves no matter what. 

oscillator = context.createOscillator();
oscillator.type = 1;

I notice that this example I found online works on Safari, gives me just a sine wave on chrome, and doesn't work on firefox (maybe because it uses oscillator.noteOn instead of oscillator.start?):

Solution

  • You need to use start(), and .type is a string type:

    oscillator = context.createOscillator();
oscillator.type = "sawtooth";
oscillator.start(0);
