(the screenshots show a white noise source running through the "Spectral EQ" insert FX, which shows a spectrum analyser (AnalyserNode) and applies a single EQ with some gain and center frequency at 1500 Hz. The AnalyserNode is after the EQ. In Chrome, the frequency response curve (blue) as returned by FilterNode.getFrequencyResponse exactly corresponds to the observed spectrum. In WebKit, it is just flat (all 1s)).
