Abstract
The present invention relates to a method of controlling a volume of a reproducing apparatus and a reproducing apparatus using the same, wherein a reproduction volume of an audio file can be automatically controlled in accordance with information on a volume level of the audio file. The reproducing apparatus of the present invention includes a memory for storing at least one audio file and volume level information for controlling a reproduction volume level of the audio file, and a control unit for controlling a reproduction volume of the audio file in accordance with the volume level information recorded corresponding to the audio file when the audio file stored in the memory is reproduced.
Claims28
A reproducing apparatus, comprising:
- a memory storing at least one audio file and volume level information for controlling a reproduction volume level of the at least one audio file, the volume level information including a value of a reproduction volume level that is controllable by a user, a controlled value of the reproduction volume level being used as a reference value for calculating offset information;
- a control unit configured to control the reproduction volume level of the at least one audio file in accordance with at least the volume level information recorded corresponding to the at least one audio file when the at least one audio file stored in the memory is reproduced;
- and
- an offset information processing unit configured to calculate the offset information based on the reference value received through a volume control input unit and recording the calculated offset information in the memory and the at least one audio file while the at least one audio file is reproduced,
- wherein the control unit is further configured to:
- reproduce the at least one audio file at a first reproduction volume level based on the volume level information, a value of the first reproduction volume level corresponding to the value of the reproduction volume level set in the apparatus, in response to an initial request for reproducing the at least one audio file or if no offset information has been recorded in the at least one audio file;
- reproduce the at least one audio file at a second reproduction volume level adjusted based on the volume level information and the offset information if the offset information has been recorded in the at least one audio file, a value of the second reproduction volume level corresponding to a sum of a value of the recorded offset information and the reference value;
- and
- reproduce the at least one audio file at a maximum or minimum reproduction volume level if a value of the sum exceeds a value of the maximum or is less than a value of the minimum reproduction volume level set in the reproducing apparatus.

A method of controlling a volume of an apparatus for reproducing at least one audio file, the method comprising:
- storing the at least one audio file and volume level information for controlling a reproduction volume of the at least one audio file in a memory, the volume level information including a value of a reproduction volume level that is controllable by a user, a controlled value of the reproduction volume level being used as a reference value for calculating offset information;
- receiving input for reproducing the at least one audio file;
- determining whether the at least one audio file to be reproduced includes the offset information;
- controlling the reproduction volume level in accordance with at least the stored volume level information when the at least one audio file stored in the memory is reproduced;
- calculating the offset information based on the reference value received through a volume control input unit and recording the calculated offset information in the memory and in the at least one audio file while the at least one audio file is reproduced;
- reproducing the at least one audio file at a first reproduction volume level based on the volume level information, a value of the first reproduction volume level corresponding to the value of the reproduction volume level set in the apparatus, in response to an initial request for reproducing the at least one audio file or when it is determined that no offset information has been recorded in the at least one audio file;
- reproducing the at least one audio file at a second reproduction volume level adjusted based on the volume level information and the offset information when it is determined that the offset information has been recorded in the at least one audio file, a value of the second reproduction volume level corresponding to a sum of a value of the recorded offset information and the reference value;
- and
- reproducing the at least one audio file at a maximum or minimum reproduction volume level if a value of the sum exceeds a value of the maximum or is less than a value of the minimum reproduction volume level set in the reproducing apparatus.
