Right. Sine sweeps may provide isolated excitation of the driver up to that amplitude, which incurs certain distortion from non-linearities at that level of excursion, but for actual signals, though their spectral envelopes over some time window may be similar, it is the actual amplitude or...

[1] To within one plot approximate the harmonic distortion that would be excited at every frequency at a given instant where the music's real-time spectrum analysis follows an amplitude distribution similar to pink noise as opposed to the case of capturing the distortion across all frequencies...

Okay. I acknowledge my mistake in not distinguishing a transfer function from a raw amplitude sweep. One could plot the amplitude versus frequency of a transducer for an input sine sweep that decreases by 3 dB, but it of course would not represent a transfer function without compensating for...

Is this to say that the " amplitude spectrum" traced out by a transfer function measurement is distinct from the output of a spectrum analyzer showing me a pink or red noise envelope for a given passage of music where both show scales in "dB SPL" or "dBFS"? Here, I am thinking of the amplitude...

So the entire measurement signal has a pink spectrum though the signal actually being passed to the transducer in the time domain is of constant amplitude. So are the distortion measurements with this sweep consistent with individual tones within pink or white noise playback through the...

Huh. I hadn't realized that consequence of the sweep rate on the amplitude. So it is already equivalent to exciting each frequency of the headphone at levels consistent with a pink noise spectral envelope (forgive my lack of the proper term)? I am a bit confused then as to what it means for this...

I am currently using REW in the context of headphone measurements. I've had success in measuring headphone distortion, but considering my observations through analyzers of contemporary music indeed having a spectral envelope similar to pink noise and classical orchestral music having one similar...
