init(self, start=0.0, duration=0.0, pitches=None, timbre=None, loudness_begin=0.0, loudness_max=0.0, time_loudness_max=0.0, loudness_end=None, kind=`'segment'`, source=None)
(Constructor)

source code

Initializes an AudioSegment.

Parameters:

start - offset from start of the track, in seconds
duration - duration of the AudioSegment, in seconds
pitches - a twelve-element list with relative loudnesses of each pitch class, from C (pitches[0]) to B (pitches[11])
timbre - a twelve-element list with the loudness of each of a principal component of time and/or frequency profile
kind - string identifying the kind of AudioQuantum: "segment"
loudness_begin - loudness in dB at the start of the segment
loudness_max - loudness in dB at the loudest moment of the segment
time_loudness_max - time (in sec from start of segment) of loudest moment
loudness_end - loudness at end of segment (if it is given)

Overrides: object.__init__

tatum

Get Method:: unreachable.tatum(self) - Returns the tatum that overlaps most with the segment Note that some segments have NO overlapping tatums. If this is the case, None will be returned.
