HYBRID DERIVATION OF SURROUND SOUND AUDIO CHANNELS BY CONTROLLABLY COMBINING AMBIENCE AND MATRIX-DECODED SIGNAL COMPONENTS |
摘要 |
<p>Ambience signal components are obtained from source audio signals, matrix-decoded signal components are obtained from the source audio signals, and the ambience signal components are controllably combined with the matrix-decoded signal components. Obtaining ambience signal components may include applying at least one decorrelation filter sequence. The same decorrelation filter sequence may be applied to each of the input audio signals or, alternatively, a different decorrelation filter sequence may be applied to each of the input audio signals.</p> |
