Uncompressed Audio File Formats
This document summarises the main features of uncompressed audio file types, including WAV, AIFF and Broadcast WAV (BWF). It gives an overview of these ‘raw’ formats, and a simple explanation of the common options they will offer the user when creating or working with digital audio. It also looks at lossless compression tools for subsequently reducing the size of these files which will allow reconstruction of their original audio data sonically unaltered. Several sections include links to further resources covering specific relevant topics in more detail, so this is a good place to start if you want to learn more about any of these formats.
