with_parameter(name, value, rate=None)¶

with_parameter_block(block_function)¶

Return a new factory configured with a parameter block function.

Use parameter block functions to build repetitive sets of SynthDef parameters, e.g. each set of band parameters for a multi-band compressor.

Parameter block functions take two parameters:

builder

the SynthDef builder instance

state

a dictionary of arbitrary key/value pairs for parameterizing the signal and parameter block functions

The return values of parameter block functions are ignored.

A factory configured to build multi-band compressor SynthDefs, using frequency bands split at frequencies:

>>> from typing import Sequence
>>> from supriya.ugens import CompanderD, LPF, Mix

>>> def parameter_block(builder, state):
...     frequencies = state["frequencies"]
...     band_count = len(frequencies) + 1
...     for i in range(band_count):
...         band_name = "band_{}_".format(i + 1)
...         builder.add_parameter(name=band_name + "pregain", value=0)
...         builder.add_parameter(name=band_name + "clamp_time", value=0.01)
...         builder.add_parameter(name=band_name + "relax_time", value=0.1)
...         builder.add_parameter(name=band_name + "threshold", value=-6)

with_parameters(**kwargs)¶

with_rand_id(rand_id=0)¶

Return a new factory configured with a random number generator ID.

>>> from supriya.ugens.factories import SynthDefFactory
>>> factory = SynthDefFactory()

>>> def signal_block(builder, source, state):
...     iterations = state.get("iterations") or 2
...     for _ in range(iterations):
...         source = supriya.ugens.AllpassC.ar(
...             decay_time=supriya.ugens.ExpRand.ir(minimum=0.01, maximum=0.1),
...             delay_time=supriya.ugens.ExpRand.ir(minimum=0.01, maximum=0.1),

...         )
...     return source
... 

>>> factory = factory.with_input()
>>> factory = factory.with_output()

>>> synthdef = factory.build()
>>> supriya.graph(synthdef)

>>> print(synthdef)

with_signal_block(block_function)¶

Return a new factory configured with an additional signal block function.

Signal block functions take three parameters:

builder

the SynthDef builder instance

source

a UGenOperable representing the signal flow

state

a dictionary of arbitrary key/value pairs for parameterizing the signal and parameter block functions

Signal block functions should return a UGenOperable.

>>> from supriya.ugens.factories import SynthDefFactory
>>> factory = SynthDefFactory()

>>> def signal_block(builder, source, state):
...     iterations = state.get("iterations") or 2
...     for _ in range(iterations):
...         source = supriya.ugens.AllpassC.ar(
...             decay_time=supriya.ugens.ExpRand.ir(minimum=0.01, maximum=0.1),
...             delay_time=supriya.ugens.ExpRand.ir(minimum=0.01, maximum=0.1),
...             source=source,
...             maximum_delay_time=0.1,
...         )
...     return source
... 

>>> factory = factory.with_input()
>>> factory = factory.with_output()
>>> factory = factory.with_signal_block(signal_block)

Configure the factory with an additional signal block:

>>> def signal_block_post(builder, source, state):
...     source = supriya.ugens.LeakDC.ar(source=source)
...     source = supriya.ugens.Limiter.ar(
...         duration=supriya.ugens.Rand.ir(minimum=0.005, maximum=0.015),
...         source=source,

>>> from supriya.ugens.factories import SynthDefFactory

...     iterations = state.get("iterations") or 2
...     for _ in range(iterations):
