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.
● 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 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 con-
tains information about the digital music file
such as song title, artist, album title, encod-
ing bit rate, track time duration, etc. ID3 tag
information is displayed on the
Album/Artist/Track title line on the display.

(models with navigation system)
Your INFINITI is equipped with Bluetooth
Streaming Audio. If you have a compatible
Bluetooth device with streaming audio (A2DP
profile), you can set up the wireless connection
between your Bluetooth device and the in-
vehicle audio system. This connection allows
you to listen to the audio from the Bluetooth
device using your vehicle speakers. It also may
allow basic control of the device for playing and
skipping audio files using the AVRCP Bluetooth
profile. All Bluetooth Devices do not have the
same level of controls for AVRCP. Please consult
the manual for your Bluetooth Device for more
details.
Once your Bluetooth device is connected to
the in-vehicle audio system, it will automati-
cally reconnect whenever the device is present
in the vehicle and you select Bluetooth Audio
from your audio system. You do not need to
manually reconnect for each usage.
