Axis

‘audio.utils.axis’ module within the ketos library

This module provides utilities to convert bin numbers to continuous variable values and vice versa.

Bins are numbered 0,1,2,3,…,N-1, counting from lower to higher values, where N is the number of bins.

By default, each bin represents a half-open interval, including the lower (left) boundary while excluding the upper (right) boudary, i.e., [a,b), except for the last bin, which represents a closed interval with both boundaries included, i.e. [a,b].
