The WAVEFORMATEX data structure defines common properties of an audio stream and occurs in a variety of multimedia file formats, including:
- Microsoft Wave
- Microsoft Audio/Video Interleaved
- Microsoft Advanced Streaming Format
- Apple QuickTime
Since the format originated on Windows/Intel computers, the defined, multi-byte numbers are stored in little endian format, even if the data structure appears in QuickTime files.
