![]() It is a “ Meta” file format developed by a company named Electronic Arts. But, before you dig into the internals of wave files, it would help to get some insights to the Interchange Format Files that form the basis for the wave file format. The wave file is the most common format for storing PCM data. The analog audio is sampled in accordance with the Nyquest theorem and the individual samples are stored sequentially in binary format. In the digital domain, PCM ( Pulse Code Modulation) is the most straightforward mechanism to store audio. I may try to address those in a separate, future article. But, the actual theory behind PCM, such as aliasing and so forth, is beyond the scope of this article. ![]() It also explains the structure of wave files and shows you how to work with them using code written in C++. This article is intended to give an overview of how PCM audio is stored and processed on a PC.
