Sound: Medium-Level Rendering
.
Name |
|
PySndObj |
Description |
|
PySndObj
is Victor Lazzarini's python
wrapper for his own object-oriented audio processing SndObj (the Sound
Object Library). SndObj is a collection of code 'objects' that can be
used to build sound-rendering applications for data sonification where
it is necessary to have direct control of the sound at a relatively
low-level, such as might otherwise be implemented with Csound or
SuperCollider Unit Generators. |
Principal
Reference |

sndobj
on
Sourceforge. |
Documentation |
|
A
PDF of the Sound Object Library is
available as a Sourceforge download.
It requires some
'interpreting' for PySndObj as it is of the C++ Library Classes. |
Version |
|
1.0.2.
Available for OSX, Linux and
win32. |

In addition
to the document referred to in
Documentation, above, there a PySndObj.pdf
of some example code which should get
you started. A direct link

Warnings |
|
None
really. Audio tasks are turned
on and off directly. |
Initial
Comments |
|
Excellent
tool, thoroughly documented. |
Speech Sound: PySpeak.
Another option is Festival
which is potentially more
powerful but requires more work.

An extendable library version is currently under development. |

Comments, below. |
Examples |
|
Until a
dynamic library and python wrapper is
built (se Warnings), we can use the "pipe of last resort" as
illustrated in the following example. This technique is useful for any
application which works with standard unix IO pipes: pyspeaker.py
|
Warnings |
|
espeak
will not compile "out of the
box" on OSX. We plan to release OSX compiled binaries and python
wrappers. |
Initial
Comments |
|
Espeak
is an object library
implementation of speak,
a modern phonenen synthesiser. We have
selected speak
as the first text-to-speech tool for data
sonification primarily because of the simplicity and adaptability of
it's architecture; It is feasible to control the whole process from
phoneme specification using espeak's
sister program espeakedit
and synthesise mutiple simultaneous voices. At the time of writing, it
does not have a python interface as is written with multiple audio
threading on the windows platform in mind. We are adapting speak
to take account of OSX's audio tools. In the mean-time it is possible
to use the "pipe of last resort" as illustratd in the example. |
