Abstract: The invention describes a method of determining the distance (d12) between two loudspeakers (L1, L2), wherein the method comprises the steps of providing a test signal (N), combining the test signal (N) with a sound signal (S) to give a combined signal (SN) in which the test signal is imperceptible to a listener (4), and issuing the combined signal (SN) by means of a first loudspeaker (L1). The combined signal (SN) is detected by a detecting means (M2) associated with the second loudspeaker (L2) and processed to obtain an acoustic impulse response (IR), which is used to determine the distance (d1,2) between the first loudspeaker (L1) and the second loudspeaker (L2). The invention further describes a system (1) for determining the distance (d1,2) between two loudspeakers (L1, L2) and an acoustic sound system, comprising a number of loudspeakers (L1, L2, . . . , Lk) for reproduction of multi-channel sound, and a system (1) for determining the distances (d1,2, d2,3, . . .

Abstract: A system (100) for processing audio data comprises an extracting unit (101) adapted to extract a transient audio data part (103) from input audio data (102) and a reverberator unit (105) which is coupled to the extracting unit (101) so as to be provided with a transient audio data part (103), wherein the reverberator unit (104) is adapted to generate reverberation separately for the transient audio data part (103).

Abstract: An audio data processing device (100), comprising a first audio data storage unit (101) and a first processor unit (102), wherein the first audio data storage unit (101) is adapted to store first audio data, wherein the first processor unit (102) is coupled to the first audio data storage unit (101) and is adapted to process the first audio data so that the first audio data is reproducible by a first audio reproduction unit (103), wherein the first processor unit (102) is adapted to be synchronized with a second processor unit (105) coupled to a second audio data storage unit (104), and the second processor unit (105) being adapted to process second audio data stored in the second audio data storage unit (104) so that the second audio data is reproducible by a second audio reproduction unit (106) synchronized to a reproduction of the first audio data by the first audio reproduction unit (104).

Abstract: An apparatus (1) comprising a display screen (150), the apparatus (1) further comprising means (24) for activating said display screen (150) to serve as a loudspeaker for reproducing an audio signal (A), means (20) for detecting if said display is viewed by a user of the apparatus, and means (22) for adjusting the reproduction of said audio signal (A) in order to reduce display distortion in dependence on said detecting (20) if said display screen (150) is viewed. An advantage of reproducing an audio signal (A) according to the invention is that audio properties normally causing optical distortion in the display screen (150) may be reproduced in situations where the user is not able to perceive the optical distortion. These audio properties may contribute to an advantageous reproduction of the audio signal (A).
