librosa.display.FJSFormatter

class librosa.display.FJSFormatter(*, fmin, n_bins, bins_per_octave, intervals, major=True, unison=None, unicode=True)

Ticker formatter for Functional Just System (FJS) notation

Parameters:

fminfloat

The unison frequency for this axis

n_binsint > 0

The number of frequency bins.

bins_per_octaveint > 0

The number of bins per octave.

intervalsstr or array of float in [1, 2)

The interval specification for the frequency axis.

See core.interval_frequencies for supported values.

majorbool

If True, ticks are always labeled.

If False, ticks are only labeled if the span is less than 2 octaves

unisonstr

The unison note name. If not provided, it will be inferred from fmin.

unicodebool

If True, use unicode symbols for accidentals.

If False, use ASCII symbols for accidentals.
