scamp_extensions.pitch package

Subpackage containing pitch-related extensions. These include abstractions for intervals and scales, as well as utilities for unit conversions.

Modules:

scamp_extensions.pitch.scale	Module containing classes for flexibly representing musical scales.
scamp_extensions.pitch.utilities	Module containing pitch-related utility functions, such as those that convert between midi and hertz.

Public-Facing API (result of import *):

PitchInterval(cents, ratio)	Represents an interval between two pitches.
Scale(scale_type, start_pitch[, cycle])	Class representing a scale starting on a specific pitch.
ScaleType(*intervals)	A ScaleType represents the intervallic relationships in a scale without specifying a specific starting point.
bark_to_freq(b)	Converts a Bark number to its corresponding frequency in hertz.
cents_to_ratio(cents)	Given a number of cents, convert it to a corresponding frequency ratio.
freq_to_bark(f)	Converts a frequency in hertz to a (floating point) Bark number according to the psychoacoustic Bark scale (https://en.wikipedia.org/wiki/Bark_scale).
hertz_to_midi(hertz_value[, A])	Given a frequency in hertz, returns the corresponding (floating point) MIDI pitch.
map_keyboard_to_microtonal_pitches(...[, ...])	Given a list of microtonal (floating-point) MIDI pitches, finds an efficient map from keyboard-friendly (integer) pitches to the original microtonal pitches.
midi_to_hertz(midi_value[, A])	Given a MIDI pitch, returns the corresponding frequency in hertz.
ratio_to_cents(ratio)	Given a frequency ratio, convert it to a corresponding number of cents.
