发明名称 Device for and a method of processing audio data
摘要 A device (100) for processing audio data, wherein the device (100) comprises a first audio reproduction unit (102) adapted for reproducing a first part of the audio data and adapted to be attached to a left ear (106) of a user (110), a second audio reproduction unit (104) adapted for reproducing a second part of the audio data and adapted to be attached to a right ear (108) of the user (110), a detection unit (112) adapted for detecting a left/right inversion of the first audio reproduction unit (102) and the second audio reproduction unit (104), and a control unit (114) adapted for controlling the first audio reproduction unit (102) for reproducing the second part of the audio data and for controlling the second audio reproduction unit (104) for reproducing the first part of the audio data upon detecting the left/right inversion.

主权项 1. A device for processing audio data, wherein the device comprises a first audio reproduction unit adapted for reproducing a first part of the audio data and adapted to be attached to a left ear of a user; a second audio reproduction unit adapted for reproducing a second part of the audio data and adapted to be attached to a right ear of the user; a detection unit adapted for detecting a left/right inversion of the first audio reproduction unit and the second audio reproduction unit, the detection unit comprising a first signal detection unit located at a position of the first audio reproduction unit and adapted for detecting a first audio detection signal and a second signal detection unit located at a position of the second audio reproduction unit and adapted for detecting a second audio detection signal; and a control unit adapted for controlling the first audio reproduction unit for reproducing the second part of the audio data and for controlling the second audio reproduction unit for reproducing the first part of the audio data upon detecting the left/right inversion, wherein the detection unit is adapted for detecting the left/right inversion based on the first audio detection signal and the second audio detection signal, and wherein the detection unit is adapted for detecting the left/right inversion by determining a time difference between the first audio detection signal detected by the first signal detection unit and the second audio detection signal detected by the second signal detection unit via calculating acoustical transfer functions between a signal emission unit and the first and second signal detection units or via correlating a reference signal emitted by the signal emission unit with the first and second audio detection signals.
