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)

len(a)

1

A Sine object with four streams:

a = Sine(freq=[250,500,750,100])

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()
