Changing audio

       The main parameter of the audio file is its volume. The program of music for theater uses the same pattern set the volume, as in professional equipment. It is assumed that the audio on the mastering stage are processed in such a way that they do not require an increase in volume. In other words, mastering all the audio recordings made in such a way as if all the audio files were merged into one and normalized.

       Therefore, a change in volume in the program music for theater means a weakening of the signal from the maximum level of 0db.

The figure shows a volume control for a single isolated event in the table an audio file (1). It is controlled using the mouse. If the pointer is located within it, then turning the mouse wheel you can change the volume level with the step 2db.

Button titled "Viewing audio" (2) opens a window where you can make the basic playback settings:

       Here are the key elements that exist in that window.

       (1)- representation by channel of the wave form. In the upper channel shows markers, and the point of beginning and end of the fade. In all other channels of markers appear only in the form of vertical lines.

       (2)- Adjust the volume. This is the same regulator, as in the figure above, only in this box, they work in pairs. Lower knob is inactive. It shows what level of attenuation was before the window "Viewing audio" was opened. Regulator (2) - active.

       (3)- Music player. Can play audio file in one of two devices - in the portal system or to watchdog device (monitoring) . Program music for theater allows you to work in the hall completely invisible to others. This feature is extremely useful in rehearsals. With this you are always ready, and no one distracts.

       (4)- Switch magnifier. Each audio file can be played either from beginning to end, either in the form of looping the loop.

       (5)- The scale of the wave display. In order to accurately fix the markers you need to consider the wave form in a very strong approximation, and the search for the desired location may require the display of all 100% of wave data.

       Consider more markers.

       Markers in blue are called start and stop playback. The sound always starts from the position of the first blue marker, and after the position of the second blue marker ends. This is true for sound, which has no looping the loop (Loop). If the Loop button is enabled (as in the figure), the sound reaching the position of the second yellow marker will go down in an endless loop between the two. Yellow markers are called "Makere start loop and end loop marker.

       At each marker, the bottom has a small rounded education. The position of these objects can not be left than the position of their markers. This slider, which is responsible for the smooth rise and decay volume. All markers have left slider rise of sound, and the position of the slider indicates the location in the audio file, where the volume reaches the value set by volume control.

       In turn, all right sliders indicate the position of the file where the sound volume reaches a minimum value. The farther away from the marker are these sliders, the more slowly fades the volume.

       All this is true for sounds obsessed mode Loop, and in order to avoid an interruption in the sound traditionally implicitly uses two audio streams.

Attenuation and sound growth of the program has a logarithmic dependence, which is perceived by man as a uniform change in volume.
