MeasurewiseAttackPointOptimizer

class quantizationtools.MeasurewiseAttackPointOptimizer

Concrete AttackPointOptimizer instance which attempts to optimize attack points in an expression with regard to the effective time signature of that expression.

>>> staff = Staff("c'8 d'8 e'8 f'8 g'8 a'8 b'8 c''8")
>>> show(staff) 
>>> source_tempo = Tempo((1, 4), 60)
>>> q_events = quantizationtools.QEventSequence.from_tempo_scaled_leaves(
...     staff[:],
...     tempo=source_tempo,
...     )
>>> target_tempo = Tempo((1, 4), 54)
>>> q_schema = quantizationtools.MeasurewiseQSchema(
...     tempo=target_tempo,
...     )
>>> quantizer = quantizationtools.Quantizer()

Without the measure-wise attack-point optimizer:

>>> result = quantizer(
...     q_events,
...     q_schema=q_schema,
...     )
>>> show(result) 

With the measure-wise attack-point optimizer:

>>> optimizer = quantizationtools.MeasurewiseAttackPointOptimizer()
>>> result = quantizer(
...     q_events,
...     attack_point_optimizer=optimizer,
...     q_schema=q_schema,
...     )
>>> show(result) 

Only acts on Measure instances.

Bases

Attribute summary

__call__(argument) Calls measurewise attack-point optimizer.
__eq__(argument) Is true when ID of argument equals ID of Abjad object.
__format__([format_specification]) Formats Abjad object.
__hash__() Hashes Abjad object.
__ne__(argument) Is true when Abjad object does not equal argument.
__repr__() Gets interpreter representation of Abjad object.

Special methods

MeasurewiseAttackPointOptimizer.__call__(argument)

Calls measurewise attack-point optimizer.

Returns none.

(AbjadObject).__eq__(argument)

Is true when ID of argument equals ID of Abjad object. Otherwise false.

Returns true or false.

(AbjadObject).__format__(format_specification='')

Formats Abjad object.

Set format_specification to ‘’ or ‘storage’. Interprets ‘’ equal to ‘storage’.

Returns string.

(AbjadObject).__hash__()

Hashes Abjad object.

Required to be explicitly redefined on Python 3 if __eq__ changes.

Returns integer.

(AbjadObject).__ne__(argument)

Is true when Abjad object does not equal argument. Otherwise false.

Returns true or false.

(AbjadObject).__repr__()

Gets interpreter representation of Abjad object.

Returns string.
