class LocalBuf(frame_count=1, channel_count=1, calculation_rate=None)¶

>>> local_buf = supriya.ugens.LocalBuf(
...     channel_count=1,

LocalBuf.ir()

LocalBuf creates a MaxLocalBufs UGen implicitly during SynthDef compilation:

...         source=source,
...     )
...     ifft = supriya.ugens.IFFT.ar(pv_chain=pv_chain)
...     out = supriya.ugens.Out.ar(bus=0, source=ifft)
...

class MaxLocalBufs(calculation_rate=None, maximum=0, **kwargs)¶

Bases: UGen

Sets the maximum number of local buffers in a synth.

Used internally by LocalBuf.

>>> max_local_bufs = supriya.ugens.MaxLocalBufs.ir(maximum=1)
>>> max_local_bufs
MaxLocalBufs.ir()

increment()¶

Increments maximum local buffer count.

>>> max_local_bufs = supriya.ugens.MaxLocalBufs.ir(maximum=1)
>>> max_local_bufs.inputs
(1.0,)

>>> max_local_bufs.increment()
>>> max_local_bufs.inputs
(2.0,)

Returns none.
