	~~=== Metrological note on waterfall source ===~~

	When using '''raw signals''', the tool applies the rigorous RPM-bin method: one independent FFT per RPM bin, driven by the tacho. This eliminates speed-smearing and gives accurate amplitudes at all orders.

	When using a '''pre-computed waterfall''' (.res), the STFT windows are fixed in time. At sweep rates above ~50 RPM/s and for orders higher than 5×, some amplitude underestimation and peak broadening may occur. For resonance location (critical speed identification), this is generally acceptable. For amplitude-critical measurements (API acceptance tests, ISO compliance), prefer raw signals with a tacho.
