| 20100034394 | METHOD AND AN APPARATUS FOR PROCESSING AN AUDIO SIGNAL - A method for processing an audio signal is disclosed. The present invention includes obtaining a stereophonic audio signal including a speech component signal and other component signals, obtaining gain values for each channel of the audio signal, determining whether the audio signal is an inverse-phase mono signal including left and right channel whose phase is inverted, inverting a phase of the obtained gain value corresponding to the one channel of the audio signal when the audio signal is an inverse-phase mono signal, modifying the speech component signal based on the inverted phase of the gain value, and generating a modified audio signal including the modified speech component signal, wherein the modified audio signal is in-phase mono signal. Accordingly, a volume of a speech signal of an inverse-phase audio signal and method thereof, in which a sign of a final gain value corresponding to one channel of the audio signal is changed or a value of the final gain corresponding to one channel of the audio signal is adjusted through a process for determining whether an input signal is an inverse-phase mono signal including left and right channel whose phase is inverted. | 02-11-2010 |
