SECTION 1: SYSTEM
Q1.1 What is a media file in A2 ?
Any audio, video and image file supported by A2 is considered to be a media file in A2, and can be "played" by adding it to the playlist.
So, A2 Media Player is not only an audio player, it is also a video player, an image displayer, a karaoke simulator, an electronic photo album generator, a multi-media electronic book generator, a multi-media dictionary generator ... , and can be used for entertainment, education and business purposes.
All versions of A2 Player after V2.2 supports the following media file formats and their attachments:
Media File Attachments
Audio File Image File (bmp, jpg, png)
(Audio CD - cda) Video File (VCD, mpg, avi)
(MPEG - mp3) A2 Lyrics File (lrc)
(Windows Media Audio - wma)
(Wave - wav)
(Midi - mid)
(Midi Karaoke - kar)
(A2 Midi Karaoke - ka2)
Image File Audio File (mp3, wma, wav, mid, kar, ka2)
(BMP Image - bmp) 2 lines of text
(JPEG Image - jpg)
(Portable Network Graphics - png)
Video File Audio File (mp3, wma, wav, mid, kar, ka2)
(Video CD - dat) Image File (bmp, jpg, png)
(MPEG Video - mpg, mpe, mpeg) A2 Lyrics File (lrc)
(AVI Video - avi)
Q1.2 What is the "title" of a media file in A2 ?
In A2, the "title" of a media file is actually the text display in the playlist. It is the same as the file name of the media file when it is loaded into the playlist the first time.
A2 allows user to modify the "title" of each media file through the "Name" page of the Media File Settings Editor (see Q2.2). This is especially useful in creating the CD and VCD playlist where the title can reflect what is actually inside each media file.
With the help of the auto play timing settings (see Q1.4), this is also a very useful tools to re-arrange different parts of a media file for playing.
In other words, 'title' is the alias of part of a media file in a playlist, and different titles in a playlist may refer to the same media file. What is actually the path and the name of the media file can be found in the "Name" page of the Media File Settings Editor (see Q2.2). If user wants to rename the the media file as the title, this can also be done in the same page.
Q1.3 What is the "Custom Order Number" of a media file ?
"Custom Order Number" is a 4-digits number assigned to each media file in a playlist to represent the playing order of the media files defined by the user. By default, the number represents the sequence of the media files added to the playlist.
User can rearrange the playing order of the media files by changing their "Custom Order Numbers" through the "Next" page of the Media File Settings Editor (see Q2.2).
The "Custom Order Number" can be set to show or hide through the "Playlist" page of Preferences. By default, the playlist is sorted by the "Custom Order Number".
Q1.4 What is Auto Play Mode (APM) ?
Auto Play Mode (APM) is actually the default playing mode of A2 Media Player V2.0. When APM is applied, media files in the playlist will be played one by one continuously until the end of the playlist is reached. In all versions of A2 Media Player after 2.0, the concept of auto play timing control is introduced to make the APM a lot more powerful than before. The auto play timing for each media file can be set and modified through the "Timing" page of the Media File Settings Editor (see Q2.2). They are:
a) Waiting Time: time to wait before the media file is actually played
b) Starting Position: starting position of the media file to be played
c) Duration: length of the part of the media file to be played
A playlist will also be played automatically when it is loaded if APM is applied.
With the help of the auto play timing settings, user is able to play a series of "chopped" media files at a specific time in any order without using any other audio or video editors (see Q1.2).
Sampling is actually applying auto playing mode with zero waiting time and zero starting position for a specific duration to all media files.
Q1.5 How to insert a silent interval between each media file ?
User can insert a silent interval between each media file by:
a) select "Preferences",
b) select the "System" page,
c) select the "Auto Play" page,
d) check the "Apply auto playing mode" checkbox,
e) check the "Apply current auto play timing settings to all media file"
checkbox,
f) enter the required silent interval for Waiting Time.
SECTION 2: PLAYLIST
Q2.1 What is A2 Playlist File (A2L) ?
A2 Playlist File (A2L) is a new type of playlist file completely different from M3U, M3L and PLS. Seeing that different media files may require to be played with a different settings of the environment at different time, A2 decided to developed a playlist which is capable of saving variables (settings) of the environment.
With the help of the auto play timing settings (see Q1.4), user is able to play a series of "chopped" media files at a specific time in any order without using any other audio or video editors. This also means that the A2 playlist can be used to synchronize media files with other actions, e.g. lectures and seminars, school stage play, party performance, ... etc.
With the help of the new "Execute" settings after Version 2.2, media files can also be made to be synchronized with the environment through external software and hardware.
So, A2 Playlist File (A2L) is actually a program - an event generator. A2 will show you more about "Playlist programming" in the coming versions.
In short, A2 playlist file let you mix "everything" together and "play" in whatever way you like.
A2 Playlist file saves the following environment settings:
Media File: Title

Q2.2 What is Media File Settings Editor (MFSE) ?
Media File Settings Editor (MFSE) is an editor for modifing all the environmental variables (settings) including all settings of attachments (except mixer settings) saved for each media file in the playlist. The editor can be activated by:
a) clicking the "Media File Settings" button (known as Media File Rename button in
V2.0) in the playlist module,
b) clicking the "Edit Media File Settings" option on the popup menu of the playlist
module (right-click the mouse on the playist to get the popup menu).
Each type of media file has its own set of settings, and are described as follows:

all media files through the Media File Settings Editor (see Q2.1 for details).
Q2.31 What is the "Custom Order" of media files in a playlist ?
In all versions after V2.2, A2 allows user to defined his/her own playing order of media files in a playlist in a more natural way. By default, media files are arranged in order of the time they are addded to the playlist with a "Custom Order Number" assigned to them.
User can re-arrange this order by changing the "Custom Order Numbers" of the media files through the "Next" page of the Media File Settings Editor (see Q2.32).
The "Custom Order Number" can be set to show or hide through the "Playlist" page of Preferences.
The "Add Media File", "Search Media File", "Load Playlist" and "Save Playlist" operations will force the playlist to be sorted by "Custom Order" no matter what order the media files are arranged before those operations.

User can change an "Auto Path Playlist" (see Q2.81) to normal A2 Playlist by re-entering the Media File Settings Editor (see Q2.2) and pressing the "Confirm" button for each media file in the playlist.
SECTION 3: LYRICS
Q3.1 What is A2 Lyrics File (A2 LRC) ?
Seeing that there are many incompatible lyrics formats made for different types of audio media files, A2 tries to develope a simple but powerful lyrics structure which can be applied to all media files.
A2 Lyrics File (A2 LRC) format is an enhancement of the LRC format introduced by Kuo (Djohan) Shiang-shiang's Lyrics Displayer which was probably the first program that tried to simulate Karaoke performance. In order to make this simulation more realistic and save more information into the lyrics file, A2 decided to make the following changes:
a) Added another time tag called "Word Time Tag" which is distinguished from
the original time tag (Line Time Tag) by the symbol '<' and '>', so that words
(or even letters) in a line can have its own timing.
b) Since the timing of the words (or letters) in each line of the repeated lines may
be different, A2 decided to omit the repeated line format. But still, A2 can read
repeated lines with "Line Time Tags".
c) Although human eyes may not be able to detect the difference in lyrics display
within 1/10 of a second in usual cases, A2 still decided to raise the accuracy of
timing from 1/10 sec to 1/100 sec so that it is able to handle all existing 'LRC'
files.
d) To save more information into the lyrics file, A2 introduced two more info tags:
"Author [au:]" and "Remarks [re:]".
e) Since there are funtions in A2 Player to add or subtract a time interval to or
from all the time tags simultaneously, A2 omitted the "[offset:]" info tag.
Below is a detailed decription of the A2 lyrics (A2 LRC) format:
[ti:Title][CR][LF]
[ar:Artist][CR][LF]
[au:Author][CR][LF]
[al:Album][CR][LF]
[by:Enter by][CR][LF]
[re:Remarks][CR][LF]
[mm:ss.xx]<mm:ss.xx>word 1 of line 1 <mm:ss.xx>word 2 of line 1 <mm:ss.xx>
... last word of line 1<mm:ss.xx>[CR][LF]
[mm:ss.xx]<mm:ss.xx>word 1 of line 2 <mm:ss.xx>word 2 of line 2 <mm:ss.xx>
... last word of line 2<mm:ss.xx>[CR][LF]
...
...
...
[mm:ss.xx]<mm:ss.xx>word 1 of last line <mm:ss.xx>word 2 of last line
<mm:ss.xx> ... last word of last line<mm:ss.xx>[CR][LF]
Empty lines for hiding previous lines or re-positioning of the next line (as top or bottom line) are coded as:
[mm:ss.xx][CR][LF]
[mm:ss.xx][CR][LF]
...
[mm:ss.xx][CR][LF]
where mm is minute, ss is second and xx is 1/100 sec., and no repeated line is allowed.
Q3.2 What is MP3 with lyrics embedded ?
A2 Media Player allows A2 Lyrics File (LRC) to be embedded into MP3 files. This can be done through:
a) the "Lyrics" page of the Media File Settings Editor (see Q2.2),
b) the "File" option on the main menu of the Lyrics Editor (see Q8.1) after a
MP3 media file is loaded.
Lyrics embedded in MP3 will be extracted and displayed in the Karaoke Emulator automatically when the MP3 media file is played. User can override this A2 action by attaching another lyrics file to the MP3 media file through the Media File Settings Editor (see Q2.2).
A2 adopts a simple and elegant way to embed the whole Lyrics File (LRC) between the ID3 tag and MP3 data at the end of the MP3 file. The Lyrics File (LRC) with its header structure (contains version, software & company information) is encapsulated inside a data block called "Lyrics Block" with block information read from the end of the file. The file structure is described as follows:
MP3 File
...
... MP3 data
...
----- ----- --------- Lyrics Block ----- ----- ---------
- Header size (2 bytes) -
- ----- ----- -------- Header ----- ----- -------- - -
- - Field size - Version Number (1 byte) - -
- - Field Data - Version Number - -
- - Field size - Software Name (1 byte) - -
- - Field data - Software Name - -
- - Field size - Company Name (1 byte) - -
- - Field data - Company name - -
- -------- ----- ------ ------------- -
- Lyrics data size = LRC file size (2 byte) - -
- ----- ----- ----- Lyrics data ----- ----- ------- - -
- - - -
- - ... - -
- - ... LRC file data - -
- - ... - -
- - - -
- -------- ----- ------ ------------- -
- -
- 00 -
- padded with byte 00 if not used -
- 00 -
- -
-------- ----- ------ ----- ----- ---------
Lyrics Block Size (2 bytes)
Block Name - "LYRICS" (6 bytes)
Block Name size - "6" (1 byte)
ID3 Tag (128 bytes, optional)
Rules for updating "Lyrics Block":
a) Header data must be written on top of the Lyrics Block.
b) Lyrics data must follow the Header data immediately.
c) All the unused area in the Lyrics Block must be padded with byte 00.
d) When the Lyrics Block is updated with a new Lyrics Block of size larger
than the original size, the Lyrics Block Size field must be updated with the new
size. Otherwise, DO NOT MODIFY this field.
Q3.3 How to modify lyrics embedded in MP3 ?
Lyrics embedded in MP3 can be extracted by loading the MP3 media file into the Lyrics Editor (see Q8.1). It is up to the user whether he wants to save the modified lyrics as a separate LRC file or to embed the lyrics into the MP3 file again (see Q3.2).
Q3.4 What is KAR file ?
KAR file is actually Midi file with lyrics embedded. A2 supports reading of KAR file only (not writing). Lyrics embedded in KAR will be extracted and displayed in the Karaoke Emulator automatically when the KAR media file is played. User can override this A2 action by attaching another lyrics file to the KAR media file through the Media File Settings Editor (see Q2.2).
A2 also allows A2 Lyrics File (LRC) to be embedded into a copy of a standard Midi file (mid or kar) and save the copied file as KA2 - A2 Midi Karaoke File (see Q3.6).
Q3.5 How to modify lyrics embedded in KAR ?
Lyrics in KAR can be extracted by loading the KAR media file in the Lyrics Editor (see Q8.1). Since A2 does not support writing of KAR file, user can only save the modified lyrics as a separate LRC file and then attach the LRC file to the KAR media file using the Media File Settings Editor (see Q2.2).
Q3.6 What is KA2 file (A2 Midi Karaoke File) ?
A2 Media Player allows A2 Lyrics File (LRC) to be embedded into a copy of a standard Midi file (mid or kar), and save the copied file as KA2 (A2 Midi Karaoke File). This can be done through:
a) the "Lyrics" page of the Media File Settings Editor (see Q2.2),
b) the "File" option on the main menu of the Lyrics Editor (see Q8.1) after a
Midi media file is loaded.
Lyrics embedded in KA2 will be extracted and displayed in the Karaoke Emulator automatically when the KA2 media file is played. User can override this A2 action by attaching another lyrics file to the KA2 media file through the Media File Settings Editor (see Q2.2).
The file structure of the embedded lyrics in KA2 is the same as that in MP3 (see Q 3.2).
Q3.7 How to modify lyrics embedded in KA2 ?
Lyrics embedded in A2 Midi Karaoke File (KA2) can be extracted by loading the KA2 media file into the Lyrics Editor (see Q8.1). It is up to the user whether he wants to save the modified lyrics as a separate LRC file or to embed the lyrics into the KA2 file again (see Q3.6).
Q3.8 How to modify lyrics settings ?
Lyrics settings (see Q2.1) can be set and modified through
a) the "Lyrics Options" option on the popup menu of the main module (right-click
the mouse on the main module skin to get the popup menu),
b) the "Lyrics Options" option on the popup menu of the A2 Theatre (Karaoke
Simulator) (right-click the mouse on the image to get the popup menu).
c) the "Lyrics" page of the Media File Settings Editor (see Q2.2).
In usual cases, lyrics should be set in the A2 Theatre (Karaoke Simulator) when the media file is playing so that what you save is what is see (see Q2.43).
Q3.9 What is "Progress Rate" in displaying lyrics ?
"Progress Rate" is the rate to fill a word with the Focused Word color set for lyrics in "Lyrics Options". If "Progress Rate" is not applied, the whole word will be filled in the Focused Word color immediately once the time set for the word is reached.
