> Firefox always clicks when starting and stopping each tone. I think that's due to a longstanding Firefox bug and not the Web Audio API. I could mostly elminate the clicks by ramping the gain, but the threshold was different for each computer.

You sure it is not due to the sound files you are using not having a normalized start?

There were no sound files. I used an oscillator and changed the gain with `setTargetAtTime` to briefly fade in and out. That should prevent any clicking, but in Firefox it required an excessive amount of time.
