Internal objects
===================================
.. currentmodule:: pyo
These objects are mainly used by pyo itself, inside other objects.
Objects in this category
------------------------------
- :py:class:`Dummy` : Dummy object used to perform arithmetics on PyoObject.
- :py:class:`InputFader` : Audio streams crossfader.
- :py:class:`Mix` : Mix audio streams to arbitrary number of streams.
- :py:class:`VarPort` : Convert numeric value to PyoObject signal with portamento.
- :py:class:`Stream` : Audio stream objects. For internal use only.

*Stream*
-----------------------------------
*class* **Stream**
Audio stream objects. For internal use only.
A Stream object must never be instantiated by the user.
A Stream is a mono buffer of audio samples. It is used to pass audio between objects and the server.
A PyoObject can manage many streams if, for example, a list is given to a parameter.
A Sine object with only one stream:
>>> a = Sine(freq=1000)
>>> print(len(a))
1
A Sine object with four streams:
>>> a = Sine(freq=[250,500,750,100])
>>> print(len(a))
4
The first stream of this object contains the samples from the 250Hz waveform. The second stream contains the samples from the 500Hz waveform, and so on.
User can call a specific stream of an object by giving the position of the stream between brackets, beginning at 0. To retrieve only the third stream of our object:
>>> a[2].out()
The method getStreamObject() can be called on a Stream object to retrieve the XXX_base object associated with this Stream.
This method can be used by developers who are debugging their programs!
