Method and apparatus for decoding parametric-encoded audio signal

A computer readable recording medium having embodied thereon a computer program for executing a decoding method, the decoding method comprising:

• extracting parameters from a parametric encoded audio signal with respect to component signals of the parametric encoded audio signal;
• adjusting the extracted parameters according to an input of a user;
• and
• synthesizing each of the component signals of the parametric encoded audio signal based on the adjusted parameters.

An audio signal decoding apparatus comprising:

• an extracting unit which extracts parameters from a parametric encoded audio signal with respect to component signals of the parametric encoded audio signal;
• an adjusting unit which selectively adjusts the extracted parameters according to an input of a user;
• and
• a synthesizing unit which synthesizes each of the component signals of the parametric encoded audio signal based on the selectively adjusted parameters.
