For Spatial or Both mode, press Analyze Noise only while the desired signal is absent. In Spectral mode, Analyze Noise establishes the baseline profile; afterward the profile progressively updates during probable noise gaps. For prerecorded files, only audio before the current playhead is analyzed. Processing On/Off bypasses or restores the existing characterization without erasing it.
