12.1. About audio files.
This section gives you some more technical information about the
types of audio files that can be used with your PLEXTALK. The file
types are as follows:
•
MP3 Files - MP3 (short for MPEG1/2 Audio Layer 3) is a
standard for the compression of audio data. It allows
compression ratios of 1/10 or even 1/12, with Music CD quality.
PLEXTALK supports the following bit rates: MPEG1 Layer 3
from 32kbps to 320kbps and MPEG2 Layer 3 from 16kbps to
160kbps. It also supports VBR (Variable Bit Rate).
Note:
For VBR, the reporting of the elapsed time and remaining time
is not accurate and should be viewed as an estimate only.
•
WAVE Files - The Wave format is Microsoft's standard audio
file format. PLEXTALK supports Wave files in PCM (Pulse
Code Modulation) format only.
•
AMR-WB+ - This is a standard for compression of audio data.
PLEXTALK supports all bit rates for this audio standard.
12.2. About playing sequences.
This section gives you information about the playing sequence used
for playing files and folders.
•
Playback of files - PLEXTALK will playback the files in the
order of their file names. In this case, numbers take
precedence over alphabetical characters. For example, if one
file is called "123ABC" and a second file is called "ABC", the
file "123ABC" will play before the file called "ABC".
•
Playback of folders - If more than one folder exists on the SD
card or USB media, the audio files will be played in the order of
the folder names.
