pyo is a Python module containing classes for a wide variety of audio signal processing types. With pyo, user will be
able to include signal processing chains directly in Python scripts or projects, and to manipulate them in real time
through the interpreter. Tools in pyo module offer primitives, like mathematical operations on audio signal, basic
signal processing (filters, delays, synthesis generators, etc.), but also complex algorithms to create sound granulation
and others creative sound manipulations. pyo supports OSC protocol (Open Sound Control), to ease communications
between softwares, and MIDI protocol, for generating sound events and controlling process parameters. pyo allows
creation of sophisticated signal processing chains with all the benefits of a mature, and wild used, general programming language.
