8. Media Player

The Media Player on the Braille Sense is a program which you can use to play audio files.  The Media Player will play the following formats, ac3, asf, asx, m3u, mp2, mp3, ogg, pls, wav, wax, wma, and wmv. Note that you will not be able to see the video with wmv files.  

You can control the playing of audio files using either the Braille keyboard commands or audio keys that are on the front panel of the Braille Sense.  The Media Player can play back recorded voices as well as music files.

8.1 Using the Audio Buttons

There are a series of buttons on the front panel of the Braille Sense.  These buttons can be used to control the Media Player.  You will find five buttons on the Braille Sense.  Starting from the left, and going to the right, the buttons are called: previous, record, stop, play/pause, and next.  These buttons are used for playing and recording music or voice quickly and easily.  

If the play/pause button is pressed while you are using a program other than the Media Player, the Braille Sense will play the files in the play list.  If there are no files in the play list, the Braille Sense says, no file in play list.  The other buttons, previous, stop, and next are available after you start playing audio by pressing the play/pause button.  Note that the record button will not work while you are using other programs.  Even if the Media Player starts when you press the play/pause button while you are using another program, the Braille Sense will not stop the program that is currently running.

8.1.1 Play/Pause Button

The play/pause button has a long, rectangle shape.  It is similar to the shape of the four function buttons, but the play/pause button is a little shorter than the four function buttons.  To locate the play/pause button, find the button that is furthest to the right on the front panel.  Then, move one button to the left.  This is the play/pause button.  With the play/pause button, you can easily play audio files registered in the play list.  If there are no files that have been registered in the play list, the Braille Sense will display the message, no file in the play list.  You have to add a file to the play list before it can be played.  There is a detailed explanation on how to add files to the play list in section 8.3.1.  If there is more than one file in the play list when you press the play/pause button, the Braille Sense will start playing all the files in the list one after another.  If you press the play/pause button again while a file is being played, the playback will be paused.  If you want to resume playing, press the button again.  If you press the play/pause button while you are in the record dialog box, the sound that was recorded most recently will be played back to you.  

8.1.2 Next button and previous button

These buttons have a triangular shape.  The previous button is the first button from the left on the front panel, and it points to the left.  The next button is the button that is farthest to the right on the front panel, and it points to the right.  If you press the next button, the next file in the play list (or recorded voice files) will be played, and pressing the previous button will play the previous file.  If you press one of these buttons while an audio file is being played, the Braille Sense will stop playing the current file, and jump to the previous or next file (depending on which button you press) in the play list, and start playing it.  If you press the next button (while the last file in the list is being played), or the previous button (while the first file in the list is being played), it will have no effect, as the Braille Sense will not stop playing the current file.

8.1.3 Record Button

The record button has a circular shape, and is used to record sound using the built-in or an external microphone.  The record button is located directly to the right of the previous button.  To use this button to record sound, you should be either in the Media Player, or in the program menu.  If you press the record button once, the Braille Sense will open the record dialog box.  If you press the record button again, the Braille Sense will resume recording.  When you press the record button while you are recording, the Braille Sense will pause your recording.  You can resume the recording by pressing the record button again.  The recorded sound will be stored in a file, and placed in the flashdisk/media/record folder.  See section 8.3.3 for more information about recorded files.

8.1.4 Stop Button

The stop button has a square shape, and is used to stop playing.  If you press the stop button while an audio file is being played, the Braille Sense will stop playing.  The next time the Braille Sense starts playing, it will start from the first file in the play list.  If you press this button while recording, the Braille Sense will stop recording.  If you press the stop button record dialog box while the Braille Sense is not recording, the dialog box will close.

8.2 Braille Keyboard and Extended Keys

You can use more of the features in the Media Player with the Braille keyboard than with the audio buttons.  You can use the Braille keyboard commands to control the player in the Media Player dialog box.  To open the Media Player, press enter on Media Player, or press m in the program menu.  The Media Player is also opened when you play audio files by pressing the play/pause button on the front panel of the Braille Sense.  This dialog box contains two information tabs:  playback information and play list.  Press space-4-5 or space-1-2 to move between these tabs.  A detailed explanation of these tabs follows in sections 8.2.1, 8.2.3, and 8.2.4.

8.2.1 Playback Information Tab

The playback information tab displays the track number, the file name, and the current playback status such as (play, pause, or stop).  If there are no files in the play list, the Braille Sense will display title: no item to be displayed.  If you press space-4, the Braille Sense will display playback time information.  

First, the elapsed or remaining time will be displayed.  You can set whether the elapsed time or remaining time will be displayed, using the playback settings dialog box as explained in section 8.3.4.2.  If you have selected the remaining time with this option, the - (minus sign), will be displayed before the time.  Next to the elapsed/remaining time, the Braille Sense will display the total playback time of the currently selected file.  

If there are no files in the play list, time: no time to be displayed will be displayed.  If you want to read the playback information of another file, move to the play list tab by pressing space-4-5, and move to the file you want by pressing space-4 or space-1 repeatedly.  Then, press space-4-5 or space-1-2 to go back to the playback information tab.  

8.2.2 Play List Tab

The play list tab displays all the files in the play list.  For each file in the play list, it displays the track number, file name, the current place of the file in the list, and the total number of files in the list.  If there is no file in the play list, the Braille Sense will display the message no file in the play list. 
 
For example, if you had the following track on the Braille Sense:  track 1  Chopin  Fantasie Impromptu  1/10, then track 1 means this file is the first item in the play list.  Chopin  Fantasie Impromptu is the file name.  1/10 means the file is the first of ten files in the play list.  Whenever you register an audio file using the file menu (as explained in section 8.3.1), the file is added to the play list.

When you want to open the Media Player menu, you can press space-m (dots 1-3-4).  You can also F2 while in the Media Player dialog box.  This menu contains four items: file, play, record and setting.  Using the file menu, you can add or delete files in the play list.  The play menu lists all of the commands related to playing files.  The record menu opens the recording dialog box in which allows you to record sound and play it.  The setting menu allows you to set various Media Player options.  A detailed explanation for each menu can be found in the section 8.3.

8.3.1 File

When you want to use the file menu, you can press space-m (dots 1-3-4) to call up the Media Player menu, and then press enter on file, or press f.  A submenu will appear, which contains file open, folder open, add file, add folder, delete item, and exit.  You can move between these items by pressing spaece-4 or space-1.  Press enter on the item you want to execute.  If you want to go back to the menu that is one level up, you can press space-e (dots 1-5).

The Braille keyboard hold option allows you to set whether or not you can use Braille keyboard commands in the Media Player.  If this is set to on, you cannot use Braille keyboard commands.  Its default value is set to off, and you can change it by pressing space on Braille keyboard hold, or by pressing the previous and next buttons on the front panel of the Braille Sense simultaneously.  While the Braille keyboard hold option is on, since you cannot use the Braille keyboard in Media Player, you should press the previous and next buttons simultaneously to turn the option off.  To save the changed settings and exit, press enter after you change an option, or move to the confirm button by pressing space-4-5 repeatedly.  If you want to cancel the changes you made, and exit this dialog box, press space-e (dots 1-5), or space-z (dots 1-3-5-6).  You can also press enter on the cancel button to close the dialog box without changing any options.  The options set in this dialog box only have an effect in Media Player.  If hold is set to off, you can call up the program menu by pressing F1, and you can use another program.

8.3.5.2 Playback Setting Dialog Box

If you press enter on playback setting, or press p on the setting menu, the playback setting dialog box will be displayed, which contains the following:  the time option, the repeat option, a confirm button, and a cancel button.  You can also open this dialog box by pressing enter-s (dots 2-3-4) in the Media Player dialog box.  You can move between these by pressing space-4-5 or space-1-2 repeatedly.  

The time option allows you to set which type of time messages will be displayed in the playback information tab.  You can set it to either elapsed time or remaining time.  You can change its value by pressing space on time.  

The repeat option allows you to set whether all files in the play list will be played repeatedly.  If it this option is set to yes, all files in the play list will be played repeatedly, and if it is set to no, the Braille Sense will stop playing after playing the last file in the play list.  Again, you can change the value of this option by pressing space on repeat.  To save the changed settings and exit from this dialog box, press enter after you change all the options you want to change, or move to the confirm button by pressing space-4-5 or space-1-2 repeatedly, and then press enter.  If you want to cancel the changes, and exit from this dialog box, press enter on the cancel button, or press space-e (dots 1-5) or space-z (dots 1-3-5-6).   

8.3.5.3 Record Setting Dialog Box

If you press enter on record setting in the settings menu, or press backspace-s in the Media Player dialog box, the Braille Sense will display the recording setting dialog box, which contains set folder, sample rate, bits per channel, and channels, as well as a confirm button and a cancel button.  You can move between these by pressing space-4-5 or space-1-2 repeatedly.  

The set folder option allows you to set the default folder where the recorded files will be saved.  Its default value is set to /flashdisk/media/record.  To specify a different folder, press enter on set folder, and the same dialog box as the folder open dialog box will be displayed.  Select a folder in the same way as in the folder open dialog box.  (Refer to section 8.3.1.2 for more information about how to select a folder.) 

The next three options are used to control the quality of recorded sound.  Higher values in sample rate, bits per channel and channels means a better quality of recorded sound, as well as a larger file size of recorded files.  In other words, if you want to record high quality sound, the total time the Braille Sense can record will be shortened.  On the other hand, if you set the lower values of these options, the Braille Sense can record sound longer, although the sound quality may not be as good as when these options are set to higher values.  You can change these values by pressing space.  If you save the changed settings, and exit from this dialog box, press enter after changing all of the options you want to change, or move to the confirm button, and press enter.  If you want to cancel the changes you made, press enter on the cancel button, or press space-e (dots 1-5).
