Expected results: 1Hz "square" oscillator connect to second osc's frequency AudioParam. It should sounds alternating 500Hz and 1500Hz .
The link is a bit wrong but almost same case. Correct link is here : http://bit.ly/1xwmQgf

(In reply to gaito from comment #0) > Actual results: > Oscillator sounds but the frequency almost remains 1000Hz. How can this be checked ? I can't tell by simply listening.
It is okay if it sounds alternate high-tone(1500Hz) and low-tone(500Hz). But the actual results are not alternating high/low tone. This is just a problem of waveform in low frequency. My friend has checked the oscillator waveform: https://qiita-image-store.s3.amazonaws.com/0/2568/8b1355ec-3c8a-6bbd-4591-15b464bc55c3.png in frequency=1Hz, the square wave is not square. I think this is a adverse effect of DC rejection filter.

Don't bother checking anything here, I'm completely changing the way this works in bug 1106649.
