Module speex

Module: speex

by David McNab <david@rebirthing.co.nz>

This Python module implements a Python wrapper to the Speex speech codec, (http://www.speex.org), providing a class called 'speex' which can be used to encode and decode streams of audio speech data
Function Summary
  new(...)
new(): Create a new speex speech stream object

Function Details

new(...)

new(): Create a new speex speech stream object

Arguments:
  • quality - 0 (lowest) to 10 (highest), default 8
The created speex stream object has two methods:

  • encode - encode a block of speech audio data

    Arguments:
    • block of audio data, as sequence of frames, where each frame is an int
    Returns:
    • raw string containing encoded data, or empty string if there is not yet any encoded data available

  • decode - decodes a block of speech audio data

    Arguments:
    • block of encoded data, as raw string,
    Returns:
    • block of audio data, as sequence of ints, or an empty sequence if there is no decoded data available yet
Notes:
  • Both of these methods use internal buffering, which means that you can feed in data piecemeal. This helps a lot when sending and receiving data over the net.

API Documentation

This document contains the API (Application Programming Interface) documentation for PySpeex - Python Bindings for Speex speech codec. Documentation for the Python objects defined by the project is divided into separate pages for each package, module, and class. The API documentation also includes two pages containing information about the project as a whole: a trees page, and an index page.

Object Documentation

Each Package Documentation page contains:

Each Module Documentation page contains:

Each Class Documentation page contains:

Project Documentation

The Trees page contains the module and class hierarchies:

The Index page contains indices of terms and identifiers:

The Table of Contents

The table of contents occupies the two frames on the left side of the window. The upper-left frame displays the project contents, and the lower-left frame displays the module contents:

Project
Contents
...		 API
Documentation
Frame
Module
Contents
 
...
 

The project contents frame contains a list of all packages and modules that are defined by the project. Clicking on an entry will display its contents in the module contents frame. Clicking on a special entry, labeled "Everything," will display the contents of the entire project.

The module contents frame contains a list of every submodule, class, type, exception, function, and variable defined by a module or package. Clicking on an entry will display its documentation in the API documentation frame. Clicking on the name of the module, at the top of the frame, will display the documentation for the module itself.

The "frames" and "no frames" buttons below the top navigation bar can be used to control whether the table of contents is displayed or not.

The Navigation Bar

A navigation bar is located at the top and bottom of every page. It indicates what type of page you are currently viewing, and allows you to go to related pages. The following table describes the labels on the navigation bar. Note that not some labels (such as [Parent]) are not displayed on all pages.

Label Highlighted when... Links to...
[Parent] (never highlighted) the parent of the current package
[Package] viewing a package the package containing the current object
[Module] viewing a module the module containing the current object
[Class] viewing a class the class containing the current object
[Trees] viewing the trees page the trees page
[Index] viewing the index page the index page
[Help] viewing the help page the help page

The "show private" and "hide private" buttons below the top navigation bar can be used to control whether documentation for private objects is displayed. Private objects are usually defined as objects whose (short) names begin with a single underscore, but do not end with an underscore. For example, "_x", "__pprint", and "epydoc.epytext._tokenize" are private objects; but "re.sub", "__init__", and "type_" are not. However, if a module defines the "__all__" variable, then its contents are used to decide which objects are private.

A timestamp below the bottom navigation bar indicates when each page was last updated.
