COMPRESSED AUDIO FILES (MP3/
WMA/AAC)
Explanation of terms
.MP3 —MP3 is short for Moving
Pictures Experts Group Audio Layer 3.
MP3 is the most well known com-
pressed digital audio file format. This
format allows for near “CD quality”
sound, but at a fraction of the size of
normal audio files. MP3 conversion of
an audio track can reduce the file size
by approximately a 10:1 ratio (Sam-
pling: 44.1 kHz, Bit rate: 128 kbps)
with virtually no perceptible loss in
quality. The compression reduces cer-
tain parts of sound that seem inaudible
to most people.
. 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. .
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.

.The playback order is the order in
which the files were written by the
writing software, so the files might not
play in the desired order.

BLUETOOTH®STREAMING AUDIO
.
Some Bluetooth®audio devices may
not be recognized by the in-vehicle
audio system.
. It is necessary to set up the wireless
connection between a compatible Blue-
tooth
®audio device and the in-vehicle
Bluetooth®module before using the
Bluetooth®streaming audio.
. The Bluetooth
®streaming audio may
be stopped under the following condi- tions:
—
Receiving a hands-free call.
—Checking the connection to the hands-
free phone.
—Connecting the hands-free phone or theaudio device.
—Downloading the phonebook memoryfrom the connected cellular phone.
. Do not place a Bluetooth®audio device
in an area surrounded by metal or far
away from the in-vehicle Bluetooth
®
module to prevent tone quality degra-
dation and wireless connection disrup-
tion.
. While an audio device is connected
through a Bluetooth
®wireless connec-
tion, the battery of the device may discharge quicker than usual.
. This system supports the Bluetooth
®
Advanced Audio Distribution Profile
(A2DP) and Audio/Video Remote Con-
trol Profile (AVRCP).
. Wireless LAN (Wi-Fi) and the Bluetooth
®
functions share the same frequency
band (2.4 GHz). Using the Bluetooth®
and the wireless LAN functions at the
same time may slow down or discon-
nect the communication and cause
undesired noise. It is recommended
that you turn off the wireless LAN (Wi-
Fi) when using the Bluetooth
®func-
tions.
