| Generally an audio sequence or program is produced
by DAW (Digital Audio Workstation) and delivered as
a digital audio file. However, the descriptive data of
the audio program, such as the cue sheet of the radio
program, is transferred apart from the audio file. The
content descriptive data is commonly known as metadata.
The most effective method to transfer the audio
data and the metadata is to embed those as one digital
file that an audio player plays and offer the description
of that audio sequence simultaneously. This paper
describes the format and scheme of the audio file
with metadata. |
