[docs]class OscBank(PyoObject):
"""
Any number of oscillators reading a waveform table.
OscBank mixes the output of any number of oscillators. The frequencies
of each oscillator is controlled with two parameters, the base frequency
`freq` and a coefficient of expansion `spread`. Frequencies are computed
with the following formula (`n` is the order of the partial):
f_n = freq + freq * spread * n
The frequencies and amplitudes can be modulated by two random generators
with interpolation (each partial have a different set of randoms).
:Parent: :py:class:`PyoObject`
:Args:
table: PyoTableObject
Table containing the waveform samples.
freq: float or PyoObject, optional
Base frequency in cycles per second. Defaults to 100.
spread: float or PyoObject, optional
Coefficient of expansion used to compute partial frequencies.
If `spread` is 0, all partials will be at the base frequency.
A value of 1 will generate integer harmonics, a value of 2
will skip even harmonics and non-integer values will generate
different series of inharmonic frequencies. Defaults to 1.
slope: float or PyoObject, optional
specifies the multiplier in the series of amplitude coefficients.
This is a power series: the nth partial will have an amplitude of
(slope ** n), i.e. strength values trace an exponential curve.
Defaults to 1.
frndf: float or PyoObject, optional
Frequency, in cycle per second, of the frequency modulations.
Defaults to 1.
frnda: float or PyoObject, optional
Maximum frequency deviation (positive and negative) in portion of
the partial frequency. A value of 1 means that the frequency can
drift from 0 Hz to twice the partial frequency. A value of 0
deactivates the frequency deviations. Defaults to 0.
arndf: float or PyoObject, optional
Frequency, in cycle per second, of the amplitude modulations.
Defaults to 1.
arnda: float or PyoObject, optional
Amount of amplitude deviation. 0 deactivates the amplitude
modulations and 1 gives full amplitude modulations.
Defaults to 0.
num: int, optional
Number of oscillators. Available at initialization only.
Defaults to 24.
fjit: boolean, optional
If True, a small jitter is added to the frequency of each partial.
For a large number of oscillators and a very small `spread`, the
periodicity between partial frequencies can cause very strange
artefact. Adding a jitter breaks the periodicity. Defaults to False.
.. seealso::
:py:class:`Osc`
.. note::
Altough parameters can be audio signals, values are sampled only once
per buffer size. To avoid artefacts, it is recommended to keep variations
at low rate (< 20 Hz).

Pulsar synthesis oscillator.
Pulsar synthesis produces a train of sound particles called pulsars
that can make rhythms or tones, depending on the fundamental frequency
of the train. Varying the `frac` parameter changes the portion of the
period assigned to the waveform and the portion of the period assigned
to its following silence, but maintain the overall pulsar period. This
results in an effect much like a sweeping band-pass filter.

TablePut takes an audio input and writes values into a table, typically
a DataTable, but only when value changes. This allow to record only new
values, without repetitions.
The play method is not called at the object creation time. It starts
the recording into the table until the table is full. Calling the
play method again restarts the recording and overwrites previously
recorded values. The stop method stops the recording. Otherwise, the
default behaviour is to record through the end of the table.

"""
An even more full control granular synthesis generator.
This granulator object offers all the same controls as the
Particle object with additionally an independently controllable
filter per grain. The filters use the same implementation as the
Biquad object.
:Parent: :py:class:`PyoObject`
:Args:
table: PyoTableObject
Table containing the waveform samples.
env: PyoTableObject
Table containing the grain envelope.
dens: float or PyoObject, optional
Density of grains per second. Defaults to 50.
pitch: float or PyoObject, optional
Pitch of the grains. Each grain samples the current value
of this stream at the beginning of its envelope and holds
it until the end of the grain. Defaults to 1.
pos: float or PyoObject, optional
Pointer position, in samples, in the waveform table. Each
grain samples the current value of this stream at the beginning
of its envelope and holds it until the end of the grain.
Defaults to 0.
dur: float or PyoObject, optional
Duration, in seconds, of the grain. Each grain samples the
current value of this stream at the beginning of its envelope
and holds it until the end of the grain. Defaults to 0.1.
dev: float or PyoObject, optional
Maximum deviation of the starting time of the grain, between 0 and
1 (relative to the current duration of the grain). Each grain samples
the current value of this stream at the beginning of its envelope
and holds it until the end of the grain. Defaults to 0.01.
pan: float or PyoObject, optional
Panning factor of the grain (if chnls=1, this value is skipped).
Each grain samples the current value of this stream at the beginning
of its envelope and holds it until the end of the grain. Defaults to 0.5.
filterfreq: float or PyoObject, optional
Center or cutoff frequency of the grain filter.
Each grain samples the current value of this stream at the beginning
of its envelope and hold it until the end of the grain. Defaults to 18000.
filterq: float or PyoObject, optional
Q of the grain filter.
Each grain samples the current value of this stream at the beginning
of its envelope and hold it until the end of the grain. Defaults to 0.7.
filtertype: float or PyoObject, optional
Type of the grain filter.
Each grain samples the current value of this stream at the beginning
of its envelope and hold it until the end of the grain. Thw value is
rounded to the nearest integer. Possible values are:
0. lowpass (default)
1. highpass
2. bandpass
3. bandstop
4. allpass
chnls: integer, optional
Number of output channels per audio stream (if chnls=2 and a stereo sound
table is given at the table argument, the objet will create 4 output
streams, 2 per table channel). Available at initialization only. Defaults to 1.
.. note::
Particle object compensate for the difference between sampling rate of the
loaded sound and the current sampling rate of the Server.
