DEVICE AND METHOD FOR CONTROLLING AUDIO SIGNAL

The present invention discloses a device and method for controlling an audio signal and includes: converting and storing first and second digital audio signals into the same sampling frequency data; extracting the first and second digital audio signals with matched audio bandwidths and then outputting the time difference between two signals as a signal for determining the time difference by using normalization cross correlation; compensating for the time difference between two signals by the signal for determining the time difference; determining a level difference with the energy of the first and second digital audio signals for which the time difference is compensated and outputting first and second gain control signals; and performing cross fading on the first and second digital audio signals and outputting the resulting signals.
