All audio files of the Voice Recorder are combined into a single list. For
each file, the parameters of tim e, date, duration and size are specified.

To select or deselect file, left-click its description. The file changes its
color depending on the choice. Two shortcut keys allow it to select all the
files and cancel selection.

Three function buttons initiate processing of the selected files. During
processing, function buttons are replaced by one cancel button (Figure 20).

File playback is enabled by the button "PLAY files" (Figure 19). At the
same time, there appear additional playback controls:

Playback

Pause

Table notes:

1. Pause playback

2. Position in the file

3. Scrolling wheel of playback position

4. Cancel playback

5. Continue Playback

The selected files are played back sequentially one after the other.

Each played file has its own progress indicator, allowing it to follow
playback process of the whole list of files.

Current position indicator of the played file 2 is located next to the
functional buttons. The position is displayed with an accuracy of 1 ms. The
file can be rewound to any position with an accuracy of 0.1 s. Rewinding
works both in pause mode, and playback mode. It is carried out using the
scroll wheel 3. The position can be adjusted roughly by wheel scrolling. More
precisely, the position can be adjusted using single-click or scrolling mouse
wheel, as well as pressing hotkeys.

You can also specify a timestamp (up to 1 second) manually. To do this,
call the dialog box by double left clicking the displayed position 2. This will
not specify the position more than 24 hours, but the files supported by the
FAT file system have the limit of 2 GB, and hence, cannot be longer than 12
hours.

For each file to be processed there appears a second icon, showing the
progress status. Icon values in playback mode are shown in the Table below:

File successfully

Erasing original files saves disk space, but does not guarantee that the file
has not been modified, since it removes the signed original. You can delete
them both.

When finished, a message displays total number of actually deleted files:

3.7.4. Opening files in external program

To extend the functionality of the program, there is a partially supported
context menu of the operating system called by right-clicking an
individu al fi le.

At the same time, regardless of the previous selections, only one file from
the list is selected (under the mouse pointer), and a menu opens (Figure 25).
The menu includes all the operations with this file type, registered in the
programs of your PC. Also, it may be helpful to use "Open With", allowing it
to select program associated with the WAV files (Figure 26).
