About MP3/WMA/AAC/M4A/WAV/FLAC/APE/DSD
Attention
Except for personal use, copyright laws and international conventions strictly prohibit the copying, distribution,
transmission or copying of audio data (including MP3/WMA/AAC/M4A/WAV/FLAC/APE/DSD data), free of charge
or for a fee, without the consent of the copyright owner.
What is MP3?
MP3, officially known as "MPEG Audio Layer 3", is a compression standard specified by MPEG, a joint
executive body under the ISO (International Organization for Standardization) and IEC. MP3 files contain
compressed audio data. The MP3 format has reduced the size of the music file to a tenth of its original size,
while still maintaining a sound quality close to that of a CD. The MP3 format achieves such a
high compression rate by excluding sounds that could not be heard by the human ear or are masked by
other sounds.
What is WMA?
WMA or "Windows Media™ Audio" is compressed audio data, and WMA is similar to MP3 audio data.
What is AAC? 一
AAC stands for "Advanced Audio Coding", which is a basic audio compression format used by MPEG2 or
MPEG4.
What is M4A?
M4A is the file extension of the MPEG-4 audio standard, M4A files contain compressed audio data.
What is WAV?
WAV is a sound file format developed by Microsoft. It conforms to the RIFF (Resource Interchange File Format)
file specification, which is used to store audio information resources for the Windows platform and is widely
supported by the Windows platform and its applications. This format also supports MSADPCM, CCITTALAW
and other compression algorithms as well as a variety of audio digital, sampling frequencies and channels; the
standard format of WAV files is the same as CD format with 44.1kHz sampling frequency and 16-bit
quantization of the digital, so the quality of the sound file and CDs is similar! It is the closest to a lossless
music format, so the file size is relatively large.
What is FLAC?
FLAC, or Lossless Audio Compression Coding, is a famous free audio compression coding that features lossless
compression. Unlike other lossy audio codecs like MP3 and AAC, it does not destroy any of the original audio
information.
What is APE?
APE is one of the popular lossless formats for digital music. Unlike lossy formats such as MP3, which
irreversibly deletes (hearing-insensitive) data in order to reduce the size of the source file, APE is a more
refined recording format that reduces the size of the file, restoring the data to the same size as the source file,
thus ensuring the integrity of the file.
What is DSD?
DSD music format is a kind of lossless music format, because its encoding is different from normal encoding, it
is a kind of digital encoding, which makes it a niche and special music format.

Method of creating MP3/WMA/AAC/M4A/WA V/FLAC/APE/DSD files
Audio data is compressed using software with MP3/WMA/AAC/M4A/WAV/FLAC/APE/DSD codecs. For details
on creating MP3/WMA/AAC/ /M4A/WAV/FLAC/APE/DSD files, please refer to the user's manual of the
software. The MP3/WMA/AAC/M4A /WAV/FLAC/APE/DSD files that can be played by this unit have the
following file extensions.
MP3 : “mp3”
WMA： “wma”
AAC： “m4a”
M4A： “m4a”
WAV： “wav”
FLAC： “flac”
APE： “ape”
DSD： “dsf” or “dff”
Files without extensions cannot be played. WMA Lossless, WMA Professional, protected files, and
original AAC files (with the extension ".aac") are not supported. There are many different versions of the AAC
format. Make sure that the software you are using conforms to the above acceptable formats. Even if the
extension is valid, it may not be a format that can be played. The playback of AAC files encoded in iTunes is
supported. APE decoding only corresponds to the ape v2 tag.

Terms
Bit rate
This is the "sound" compression ratio specified for coding. The higher the bit rate, the better the sound
quality, but the larger the file.
Sampling frequency
This value represents the number of times data is sampled (recorded) per second. For example, music
CDs use a sampling frequency of 44.1KHz, so sound is sampled (recorded) at 44,100 times per second.
The higher the sampling frequency, the better the sound quality, but the larger the data volume.
Code
Converts music CDs, wave (AIFF) files and other sound files to specified audio compression format.
Marker

Store sound setting parameters
After purchase and installation of this product by the designated Alpine authorized dealer, professional
technicians will debug and store the sound for you and set the relevant parameters for "dealer settings".
In addition to "dealer settings", if you have your own preferences, after setting the preset equalizer, bass, treble,
frequency division and other sound parameters, select "custom settings", and long press the knob for more than
2 seconds to store the debugged sound parameters in the "custom settings".

15
Call the stored sound to set parameters
After selecting "dealer settings" or "custom settings", press the knob briefly to call up the adjusted sound setting
parameters.
Notes:
•The stored contents will not be deleted even when the Media Player is reset, or the battery is disconnected.
•Dealer settings: can only be selected and recalled, can only be stored when using the power check mode.
•Custom settings: can be called, stored and modified.
About Time Correction
The distance between the listener and the interior speakers can vary greatly due to different speaker placements.
This distance difference between the speaker and the listener will cause the deviation of audio and frequency
characteristics. This phenomenon is caused by the delay in the arrival of the sound to the listener's right and left
ears.
To solve this problem, the unit can delay the audio signal sent to the speaker nearest to the listener. This
effectively creates a sense of extended distance for these loudspeakers. The distance between the listener and the
left and right speakers should be equal to obtain the best effect. Adjust the loudspeakers with 3.4cm as the level
difference.
The following is an example of a listening position:
Example 1: Left front seat
Adjust the time correction level of the left front speaker to a larger value and the right rear speaker to zero or a
smaller value.
The listening position and the distance between each speaker are different, so the sound is unbalanced.
The difference in distance between the left front speaker and the right rear speaker is 1.75m (68-7/8").
Here we will calculate the time-corrected value of the left front speaker in the above figure.

16
Conditions:
Farthest speaker - listening position: 2.25m (88-9/16")
Left front speaker - listening position: 0.5m (19-11/16")
Calculation: L = 2.25m-0.5m = 1.75m (68-7/8")
Time correction = 1.75 + 343 * X 1000 = 5.1 (ms)
* Sound speed: 20°. 343m / S (765mph)
In other words, setting the time correction value of the left front speaker to 5.1ms can make the distance between
the left front speaker and the listener be the same as that between the listener and the farthest speaker. Time
correction eliminates the difference in time required for the sound to reach the listening position.
The time of the left front speaker is corrected by 5.1ms so that its sound will reach the listening position at the
same time as the sound of other speakers.

17
Example 2: All seats
Adjust the time correction level of each loudspeaker to almost the same.
1. Sit in the listening position (driving position, etc.) and measure the distance (m) between the head and each
speaker.
2. Calculate the distance correction difference between the farthest speaker and other speakers.
L = (distance from farthest speaker) - (distance from other speakers)
These values are time corrected values for different loudspeakers. By setting these values, each sound can
reach the listening position at the same time as the sound from other speakers.
