Detailed Description

A band-compressed, rate-independent copy of a LongTermSpectrum's estimate, for saving with a session and restoring warm.

kBands log-spaced bands from 10 Hz to 24 kHz (the first band reaches down to DC, the last up to Nyquist). Powers are normalised so the wet leg sums to 1; level_ms is the wet leg's K-weighted mean square, which restores the level the level-drop rule compares against.
