ARTIFICIAL BANDWIDTH EXPANSION METHOD FOR A MULTICHANNEL SIGNAL
摘要
Techniques for applying artificial bandwidth expansion to a multichannel signal are described. Aspects of a system for applying artificial bandwidth expansion to a multichannel signal include an estimation component for receiving a multichannel signal and estimating delay and energy level differences for each channel of the multichannel signal. An artificial bandwidth expansion component artificially expands the bandwidth of each of the channels of the multichannel signal separately. Each one of a plurality of adjustment components are configured to modify a different one of the artificial bandwidth expanded channels of the multichannel signal based upon the estimated delay and energy level differences. The multichannel signal may be a binaural speech signal.
