FIELD: physics.
SUBSTANCE: device contains a controller, a memory element, a data processor, an audio processor, a RF unit, an automatic volume controlling device, an information display device, an image processor, a camera module, a keyboard, an audio player, a microphone, a loudspeaker, a representative volume extracting unit, a reference volume extracting unit, a comparison unit, an amplification factor extracting unit, a pre-processor. The method of regulating the volume in a terminal determines, whether the automatic volume control is set, switches the volume to the automatic control mode, and sets the overall volume level of the last played audio file as a reference volume. The controller sets the predefined value as a reference volume, if the playlist has no audio file, extracts the amplification factor from the header of each of the plurality of frames, extracts the average factor for all amplification factors extracted from the audio file, sets the extracted average amplification factor as a representative volume, compares the representative volume with the reference volume and adjusts the overall volume, and then plays the file.
EFFECT: increasing the efficiency of the automatic volume control.
