.WMA —Windows Media Audio (WMA) is
a compressed audio format created by
Microsoft as an alternative to MP3. The
WMA codec offers greater file compres-
sion than the MP3 codec, enabling
storage of more digital audio tracks in
the same amount of space when
compared to MP3s at the same level
of quality.
. AAC/M4A —Advanced Audio Coding
(AAC) is a lossy audio compression
format. Audio files that have been
encoded with AAC are generally smaller
in size and deliver a higher quality of
sound than MP3.
. Bit rate —Bit rate denotes the number
of bits per second used by a digital
music file. The size and quality of a
compressed digital audio file is deter-
mined by the bit rate used when
encoding the file.
. Sampling frequency —Sampling fre-
quency is the rate at which the samples
of a signal are converted from analog to
digital (A/D conversion) per second.
. Multisession —Multisession is one of
the methods for writing data to media.
Writing data once to the media is called
a single session, and writing more than once is called a multisession.
. ID3/WMA Tag —The ID3/WMA tag is the
part of the encoded MP3 or WMA file
that contains information about the
digital music file such as song title,
artist, album title, encoding bit rate,
track time duration, etc. ID3 tag in-
formation is displayed on the Album/
Artist/Track title line on the display.
