METHOD FOR RENDERING A STEREO SIGNAL |
摘要 |
The invention relates to a method (500) for rendering a stereo audio signal (402) over a first loudspeaker (401) and a second loudspeaker (403) with respect to a desired direction (201), the stereo audio signal (402) comprising a first audio signal component (L) and a second audio signal component (R), the method (500) comprising: providing (501) a first rendering signal (408) based on a combination of the first audio signal component (L) and a first difference signal (diff_L) obtained based on a difference (diff) between the first audio signal component (L) and the second audio signal component (R) to the first loudspeaker (401), and providing a second rendering signal (410) based on a combination of the second audio signal component (R) and a second difference signal (diff_R) obtained based on the difference (diff) between the first audio signal component (L) and the second audio signal component (R) to the second loudspeaker (403), such that both difference signals (diff_L, diff_R) are different with respect to sign and one difference signal is delayed by a delay (τ) compared to the other difference signal to define a dipole signal, wherein the delay (τ) is adapted according to the desired direction (201). |
