WAVE File Format is a file format for storing digital audio (waveform) data. It supports a variety of bit resolutions, sample rates, and channels of audio. This format is very popular upon IBM PC (clone) platforms, and is widely used in professional programs that process digital audio waveforms. It takes into account some peculiarities of the Intel CPU such as little endian byte order.

This format uses Microsoft's version of the Electronic Arts Interchange File Format method for storing data in "chunks".
