time is recorded in the format "hour:minute:second.subsecond," with a colon in between each time unit and a
period before the subsecond position.
Hour, minute and second are written as two digits each, with the first digit a zero if the value is one digit.
Subseconds may be expressed to any desired decimal place. If there is no subsecond information, the string ends
with a period only.
The order of time units is hour, minute, second, subsecond. The information is written as an ASCII string, so it shall
be terminated with NULL. Recording this information is optional.
Ex.) "10:05:10.130"Z
ecor

emdl
Records the model name of the equipment on which the Exif audio file was created. The model name is written in
an ASCII string and terminated with NULL. Recording this information is optional.

As with Exif image files, this chunk is used by the writer manufacturer to record design information, version history
and other maker-specific information. The contents and format of the information are up to each manufacturer.
Other manufacturers see this information only as a byte array of the size determined by the chunk size ( ckSize).
Recording this information is optional.
eucm
