Overview of this book

Multimedia applications are used by a range of industries to enhance the visual appeal of a product. This book will teach the reader how to perform multimedia processing using Python. This step-by-step guide gives you hands-on experience for developing exciting multimedia applications using Python. This book will help you to build applications for processing images, creating 2D animations and processing audio and video. Writing applications that work with images, videos, and other sensory effects is great. Not every application gets to make full use of audio/visual effects, but a certain amount of multimedia makes any application a lot more appealing. There are numerous multimedia libraries for which Python bindings are available. These libraries enable working with different kinds of media, such as images, audio, video, games, and so on. This book introduces the reader to the most widely used open source libraries through several exciting, real world projects. Popular multimedia frameworks and libraries such as GStreamer,Pyglet, QT Phonon, and Python Imaging library are used to develop various multimedia applications.

Preface

Chapter 5. Working with Audios

Decades ago, silent movies lit up the screen—but later, it was audio effect that brought life into them. We deal with digital audio processing quite frequently—when just playing a CD track, recording your own voice or converting songs into a different audio format. There are many libraries or multimedia frameworks available for audio processing. This chapter teaches some common digital audio processing techniques using Python bindings of a popular multimedia framework called GStreamer.

In this chapter, we shall:

  • Learn basic concepts behind GStreamer multimedia framework

  • Use GStreamer API for audio processing

  • Develop some simple audio processing tools for 'everyday use'. We will develop tools that will batch convert audio file formats, record an audio, and play audio files

So let's get on with it!
