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

Time for action – audio file format converter


Let's write a simple audio file converter. This utility will batch process input audio files and save them in a user-specified file format. To get started, download the file AudioConverter.py from the Packt website. This file can be run from the command line as:

python AudioConverter.py [options]

Where, the [options] are as follows:

  • --input_dir : The directory from which to read the input audio file(s) to be converted.

  • --input_format: The audio format of the input files. The format should be in a supported list of formats. The supported formats are "mp3", "ogg", and "wav". If no format is specified, it will use the default format as ".wav".

  • --output_dir : The output directory where the converted files will be saved. If no output directory is specified, it will create a folder OUTPUT_AUDIOS within the input directory.

  • --output_format: The audio format of the output file. Supported output formats are "wav" and "mp3".

    Let's write this code now.
