Function gaborator_sys::bandpass_bands_begin

pub fn bandpass_bands_begin(b: &Analyzer) -> i32

Return the smallest valid bandpass band number, corresponding to the highest-frequency bandpass filter.

The frequency bands of the analysis filter bank are numbered by nonnegative integers that increase towards lower (sic) frequencies. There is a number of bandpass bands corresponding to the logarithmically spaced bandpass analysis filters, from near 0.5 (half the sample rate) to near fmin, and a single lowpass band containing the residual signal from frequencies below fmin.
