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 compressed 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 (Sampling: 44.1
kHz, Bit rate: 128 kbps) with virtually no
perceptible loss in quality. The compression
reduces certain parts of sound that seem
inaudible to most people.
. WMA — Windows Media Audio (WMA) is a
compressed audio format created by Micro-
soft as an alternative to MP3. The WMA
codec offers greater file compression 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 determined by the bit rate used
when encoding the file. .
Sampling frequency — Sampling frequency
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 information is displayed on the
Album/Artist/Track title line on the display.
. AAC — Advanced Audio Coding (AAC) is a
compressed audio format. AAC offers great-
er file compression than MP3 and enables
music file creation and storage at the same
quality as MP3.

BLUETOOTH ŠSTREAMING AUDIO
.Some Bluetooth Šaudio 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
Šaudio device and the in-vehicle Blue-
tooth Šmodule before using the Bluetooth Š
streaming audio.
. The Bluetooth
Šstreaming audio may stop
playing when
— receiving a hands-free call.
— checking the connection to the hands- free phone.
— connecting the hands-free phone or the audio device.
— downloading the phonebook memory from the connected cellular phone.
. Do not place a Bluetooth
Šaudio device in an
area surrounded by metal or far away from
the in-vehicle Bluetooth
Šmodule to prevent
tone quality degradation and wireless con-
nection disruption. .
While an audio device is connected through
a Bluetooth
Šwireless connection, the bat-
tery of the device may discharge quicker than
usual.
. This system supports the Bluetooth
ŠAd-
vanced Audio Distribution Profile (A2DP)
and Audio/Video Remote Control Profile
(AVRCP) .
. Wireless LAN (Wi-Fi) and the Bluetooth
Š
functions share the same frequency band
(2.4 GHz) . Using the Bluetooth Šand the
wireless LAN functions at the same time may
slow down or disconnect the communication
and cause undesired noise. It is recom-
mended that you turn off the wireless LAN
(Wi-Fi) when using the Bluetooth
Šfunctions.
