Module selection

source code

Selection filters as utilities for echonest.audio.

For convenience, intended to be imported as:

from audio.selection import *

The functions in this module each return another function that takes one argument, an AudioQuantum, and returns an AudioQuantum or None.

By convention, all of these functions are named to be verb phrases that agree with a plural noun in a restrictive clause introduced by that, as in:

analysis.segments.that(fall_on_the(1))
