Great idea! Just FYI I'm noticing a fair bit of static when playing the various tones. It's mostly at the beginning, which makes me think it's just due to the discontinuity at the beginning (maybe start the volume at zero and quickly increase?) But I'm getting blips of static in the middle of most tones as well, so there must be something else going on. Tried both Chrome and Firefox. I suppose this could be an artifact from my onboard sound card or something like that, but I haven't noticed anything similar elsewhere.
