In Case Of Difficulty - Alpine UTE-80B Owner's Manual

Supported playback sampling rates and bit rates
MP3
Sampling rates: 48 kHz, 44.1 kHz, 32 kHz, 24 kHz, 22.05 kHz, 16 kHz,
12 kHz, 11.025 kHz, 8 kHz
Bit rates: 8 - 320 kbps
This device may not play back correctly depending on sampling rates.
ID3 tags
This device supports ID3 tag v1 and v2 tag.
If tag data is in an MP3 file, this device can display the title (track title),
artist name, and album name ID3 tag data.
This device can only display single-byte alphanumeric characters (up to
30 for ID3 tags) and the underscore. For non-supported characters, "NO
SUPPORT" is displayed.
If information contains characters other than ID3 tag information, the
audio file may not be played back.
The tag information may not be correctly displayed, depending on the
contents.
Playing back MP3
MP3 files are prepared, then stored to a USB Memory Device. This unit
can recognise at most 100 folders and 100 files per folder stored in USB
Memory. Playback may not be performed if a USB Memory Device
exceeds the limitations described above.
Do not make a file's playback time more than 1 hour.
Media supported
This device can play back files stored on USB Memory devices designed
for USB connection.
Corresponding File Systems
This device supports FAT 12/16/32 for USB Memory devices.
Terminology
Bit rate
This is the "sound" compression rate specified for encoding. The higher
the bit rate, the higher the sound quality, but also the larger the files.
Sampling rate
This value shows how many times per second the data is sampled
(recorded). For example, music CDs use a sampling rate of 44.1 kHz, so
the sound is sampled (recorded) 44,100 times per second. The higher
the sampling rate, the higher the sound quality, but also the larger the
volume of data.
Encoding
Converting music CDs, WAVE (AIFF) files, and other sound files into the
specified audio compression format.
Tag
Song information such as track titles, artist names, album names, etc.,
written into MP3 files.
Root folder
The root folder (or root directory) is found at the top of the file system.
The root folder contains all folders and files. It is created automatically
for all burned discs.
