  • Publication number: 20080118084
    Abstract: A method and apparatus to enhance a low frequency component of an audio signal, by computing a fundamental frequency of an input audio signal using the input audio signal and a delayed audio signal obtained by delaying the input audio signal by a predetermined amount of time, generating harmonic signals from the input audio signal based on the fundamental frequency, and combining the harmonic signals and the input audio signal. The low frequency component of the audio signal can be enhanced using human characteristics of perception without physically boosting the energy of the low frequency component.

  • Publication number: 20070140497
    Abstract: An active audio matrix decoding method and apparatus to generate multi-channel audio signals from a stereo channel audio signal. The method includes: decoding a stereo channel audio signal into a multi-channel signal, extracting a power vector of each channel signal by multiplying a magnitude of each decoded channel signal by positions of a plurality of channel speakers, extracting a vector of a virtual sound source existing between each channel by linearly combining power vector values of each decoded channel, extracting a vector value of a dominant sound image by linear combination of the vectors of the extracted virtual sound sources and normalizing the position of each channel speaker with respect to the vector value of the dominant sound image, and distributing a gain value to each channel position by comparing the magnitude of an entire decoded channel signal with the magnitude of each channel signal.

  • Publication number: 20070129036
    Abstract: A method and apparatus to restore a high frequency component. A correlation between an input signal and previously stored noise samples is obtained and a bandwidth of the input signal is detected according to the correlation. The detected input signal bandwidth is split into a predetermined number of sub-bands. A level of high frequency sub-band signals generated by performing a predetermined nonlinear operation on the split sub-bands is controlled in response to energy levels of the high frequency sub-bands to obtain restored signals. The restored signals and the input signal are combined to generate a target audio signal.

  • Publication number: 20060078305
    Abstract: A method and an apparatus to synchronize an audio signal and a video signal. The method includes: displaying video on a screen that corresponds to an audio signal including a high frequency component having a predetermined pattern inserted therein to indicate when a scene change occurs in a video signal, detecting a scene change in the displayed video and detecting the high frequency component having the predetermined pattern in the audio signal, calculating a time difference between a time when the scene change is detected in the displayed video and a time when the high frequency component having the predetermined pattern is detected in the audio signal, and controlling delay times of the audio signal and the video signal according to the calculated time difference. Accordingly, the audio signal and the video signal can be automatically synchronized without performing a separate measuring operation.
