audiostream

This library provides audio streams and is based on the standard stdio library.

In fact an audio stream can be modelled as an std stream which:

• contains multichanel interleaved pcm data
• provides additional audio specific information required to playback the stream

Stream-based I/O

The audiostream library is organized around abstract input/output audio devices. These abstract devices allow the same code to handle input/output to files, memory streams, or custom adaptor devices that perform arbitrary operations (e.g. codec specific audio decoding) on the fly.

Abstraction

• audio::istream: wraps a given abstract audio device and provides high-level output interface
• audio::ostream: wraps a given abstract audio device and provides high-level input interface

File I/O implementation

• audio::ifstream: implements high-level audio file stream input operations
• audio::ofstream: implements high-level audio file stream output operations
