Reduce high (and low, where a band is under the crossover) to nBands log-spaced bands.
The bands tile [fMin, fMax] evenly in log frequency; a band's hz is its GEOMETRIC centre,
which is the point that is visually centred on a log axis. Omitting low reproduces the exact
single-tier result, which is what an offline or synthesised frame gets.
nBands below 1 answers an empty set: a caller asking for no bands is asking for nothing, and
that is not the same as a silent spectrum.
