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
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 com-
pared 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 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 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
greater file compression than MP3 and
enables music file creation and storage
at the same quality as MP3.

Playback order
.The folder names of folders not contain-
ing compressed audio files are not shown
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.
. Music playback order of compressed
audio files is as illustrated.

BLUETOOTH® 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® audio.
. The Bluetooth® 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.
. The Bluetooth® audio may be discon-
nected if you are using wireless Apple
CarPlay® (if so equipped).
“Apple CarPlay®” (page 5-19)
. 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 degrada- tion and wireless connection disruption.
. 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 Blue-
tooth® functions share the same fre-
quency band (2.4 GHz). Using the
Bluetooth® and the wireless LAN func-
tions at the same time may slow down or
disconnect the communication and cause
undesired noise. It is recommended that
you turn off the wireless LAN (Wi-Fi) (if
so equipped) when using the Bluetooth®
functions.
