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).

    Parentclass: PyoObject

    Parameters:

    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.

    Pulsar synthesis oscillator.

    Pulsar synthesis produces a train of sound particles called pulsars

    period assigned to the waveform and the portion of the period assigned 
    to its following silence, but maintain the overall pulsar period. This

    TableRec is for writing samples into a previously created NewTable.

    See `NewTable` to create an empty table.

    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 samples.

    Parentclass: PyoObject

    Parameters:

    input : PyoObject
        Audio signal to write in the table.
    table : NewTable
        The table where to write samples.
    fadetime : float, optional
        Fade time at the beginning and the end of the recording 
        in seconds. Defaults to 0.

    Methods:

    setInput(x, fadetime) : Replace the `input` attribute.
    setTable(x) : Replace the `table` attribute.
    play() : Start the recording at the beginning of the table.
    stop() : Stop the recording. Otherwise, record through the 
        end of the table.

    Attributes:

    input : PyoObject. Audio signal to write in the table.
    table : NewTable. The table where to write samples.

    Notes:

    The out() method is bypassed. TableRec returns no signal.

    TableRec has no `mul` and `add` attributes.

    TableRec will sends a trigger signal at the end of the recording. 
    User can retrieve the trigger streams by calling obj['trig']. In
    this example, the recorded table will be read automatically after
    a recording:

    >>> a = Input(0)
    >>> t = NewTable(length=1, chnls=1)
    >>> rec = TableRec(a, table=t, fadetime=0.01)
    >>> tr = TrigEnv(rec['trig'], table=t, dur=1).out()
    
    obj['time'] outputs an audio stream of the current recording time, 
    in samples.

    Examples:

    >>> s = Server(duplex=1).boot()
    >>> s.start()
    >>> t = NewTable(length=2, chnls=1)
    >>> a = Input(0)

    TrigTableRec is for writing samples into a previously created NewTable.

    See `NewTable` to create an empty table.

    Each time a "trigger" is received in the `trig` input, TrigTableRec
    starts the recording into the table until the table is full.

    Parentclass: PyoObject

    Parameters:

    input : PyoObject
        Audio signal to write in the table.
    trig : PyoObject
        Audio signal sending triggers.
    table : NewTable
        The table where to write samples.
    fadetime : float, optional
        Fade time at the beginning and the end of the recording 
        in seconds. Defaults to 0.

    Methods:

    setInput(x, fadetime) : Replace the `input` attribute.
    setTrig(x, fadetime) : Replace the `trig` attribute.
    setTable(x) : Replace the `table` attribute.

    Attributes:

    input : PyoObject. Audio signal to write in the table.
    trig : PyoObject. Audio signal sending triggers.
    table : NewTable. The table where to write samples.

    Notes:

    The out() method is bypassed. TrigTableRec returns no signal.

    TrigTableRec has no `mul` and `add` attributes.

    TrigTableRec will sends a trigger signal at the end of the recording. 
    User can retrieve the trigger streams by calling obj['trig'].

    obj['time'] outputs an audio stream of the current recording time, 
    in samples.

class TablePut(PyoObject):
    """
    Writes values, without repetitions, from an audio stream into a DataTable.

    See `DataTable` to create an empty table.

    TablePut takes an audio input and writes values into 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.

    Parentclass: PyoObject

    Parameters:

    input : PyoObject
        Audio signal to write in the table.
    table : DataTable
        The table where to write values.

    Methods:

    setInput(x, fadetime) : Replace the `input` attribute.
    setTable(x) : Replace the `table` attribute.
    play() : Start the recording at the beginning of the table.
    stop() : Stop the recording. Otherwise, record through the 
        end of the table.

    Attributes:

    input : PyoObject. Audio signal to write in the table.
    table : DataTable. The table where to write values.

    Notes:

    The out() method is bypassed. TablePut returns no signal.

    TablePut has no `mul` and `add` attributes.

    TablePut will sends a trigger signal at the end of the recording. 
    User can retrieve the trigger streams by calling obj['trig'].

    Examples:

    >>> s = Server().boot()
    >>> s.start()
    >>> t = DataTable(size=16)
    >>> rnd = Choice(range(200, 601, 50), freq=16)
    >>> rec = TablePut(rnd, t).play()
    >>> met = Metro(.125).play()
    >>> ind = Counter(met, max=16)
    >>> fr = TableIndex(t, ind, mul=[1,1.005])
    >>> osc = SineLoop(fr, feedback=.08, mul=.3).out()
