5.7 Data Description
5.7.1 File Naming Stipulation
The file name and characters used for file names are not specified, other than to stipulate the use of ASCII
alphanumerics. (File names in Japanese or other character sets are not to be used.) File names shall be 8
characters or fewer, not including the extension. (Long file names are not to be used.) The file extension is ".WAV"
(to match the WAVE Form Audio File extension) regardless of the audio data format type.
5.7.2 Typical Exif Audio File
Typical Exif Audio File Figure 51 shows the configuration of a typical Exif audio file.
The shaded parts of Figure 51 are the mandatory elements of an Exif audio file. The hatching (fact-ck only) means
that this chunk is not required if the audio data is PCM (Pulse Code Modulation) format, but is mandatory for all
non-PCM formats (m-Law, IMA-ADPCM), etc. The non-shaded elements are optional.
