METHOD FOR INTER-CHANNEL DIFFERENCE ESTIMATION AND SPATIAL AUDIO CODING DEVICE |
摘要 |
Methods and devices for a low complex inter-channel difference estimation are provided. A method for the estimation of inter-channel differences, ICD, comprises applying a transformation from a time domain to a frequency domain to a plurality of audio channel signals, calculating a plurality of ICD values for the ICDs between at least one of the plurality of audio channel signals and a reference audio channel signal over a predetermined frequency range, each ICD value being calculated over a portion of the predetermined frequency range, calculating, for each of the plurality of ICD values, a weighted ICD value by multiplying each of the plurality of ICD values with a corresponding frequency-dependent weighting factor, and calculating an ICD range value for the predetermined frequency range by adding the plurality of weighted ICD values. |
