Rewindable
(sampling_rate, sample_width, channels)[source]¶ Base class for rewindable audio streams.
Subclasses should implement a method to return back to the start of an the stream (rewind), as well as a property getter/setter named position that reads/sets stream position expressed in number of samples.

__init__
(sampling_rate, sample_width, channels)¶ Initialize self. See help(type(self)) for accurate signature.
