Embodiment Construction

[0054] Reference will now be made in detail to embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to like parts throughout. The embodiments are described below in order to explain the present general inventive concept by referring to the figures.

[0055] figure 1 is a block diagram of an apparatus for post-processing an audio signal according to an embodiment of the present general inventive concept.

[0056] refer to figure 1 , the device includes: a mode selector 110 and a processing unit 120 .

[0057] The mode selector 110 selects one of a plurality of audio signal processing modes, which may be classified based on timbre, intensity, and tempo of the audio signal. However, the processing mode is not limited thereto, and may include other audio signal processing modes.

[0058] When a user inputs a signal to select a predetermined treatment mode by using the input u...

Abstract

A method and device for post-processing audio signals. The method includes: selecting one of a plurality of audio signal processing modes classified based on at least one of timbre, intensity, and tempo of the audio signal; and modifying the timbre, intensity, and tempo of the audio signal based on the selected audio signal processing mode. At least one of the rhythms.

Description

[0001] This application claims priority from Korean Patent Application No. 10-2006-0134984 filed on December 27, 2006 in the Korean Intellectual Property Office, which is hereby incorporated by reference in its entirety. technical field [0002] The present general inventive concept relates to a method and apparatus for post-processing an audio signal. Background technique [0003] By classifying music using genre information (classic, jazz, rock, etc.) provided by manufacturers, most sound reproduction apparatuses employ equalization filters based on genre classification. The equalization filter causes the sound reproduction device to output a balanced audio signal corresponding to the selected genre by adjusting the frequency characteristics of the audio signal. [0004] However, since the number of digital music sources is constantly increasing, resulting in huge music databases, listeners need various access methods to search for desired music. One of the access methods...
