Method and apparatus for managing audio signals

Abstract

A method comprising: detect a first acoustic signal by using a microphone array; detecting a first angle associated with a first incident direction of the first acoustic signal; and storing, in a memory, a representation of the first acoustic signal and a representation of the first angle.

What is claimed is: 
     
         1 . A mobile communication device comprising:
 a display;   memory to store audio data, the audio data including a first and second sound signals received from an outside of the mobile communication device, the first sound signal corresponding to a first direction with respect to the mobile communication device, the second sound signal corresponding to a second direction with respect to the mobile communication device, the first sound signal to be output in a first section of the audio data, the second sound signal to be output in a second section of the audio data; and   a processor adapted to:   reproduce the audio data;   present, via a first graphic user interface a first indication at a first position associated with the first direction, and a second indication at a second position associated with the second direction, in relation with the reproducing; and   present, via a second graphic user interface, a third indication indicative of the first section and a fourth indication indicative of the second section, in relation with the reproducing.   
     
     
         2 . The mobile communication device of  claim 1 , wherein: the processor is adapted to:
 adjust, a volume of a corresponding one of the first sound signal and the second sound signal, based at least in part on another user input from the first graphical user interface.   
     
     
         3 . The mobile communication device of  claim 2 , wherein the processor is adapted to: mute the volume, as at least part of the adjusting. 
     
     
         4 . The mobile communication device of  claim 2 , wherein the processor is adapted to:
 deactivate a corresponding one of the first section and the second section, based at least in part on the user input, as at least part of the muting.   
     
     
         5 . The mobile communication device of  claim 2 , wherein the processor is adapted to:
 change, via the display, at least one visual characteristic, a text, a number, or an image of a corresponding one of the first indication and the second indication, based at least in part on the user input.   
     
     
         6 . The mobile communication device of  claim 2 , wherein the first sound signal corresponding to the first direction with respect to the mobile communication device and the second sound signal corresponding to the second direction with respect to the mobile communication device, wherein the processor is adapted to:
 display a graphic user interface including the substantially circular element in relation with the reproducing, the graphic user interface including a first element having a first angle indicative of the first direction and a second element having a second angle indicative of the second direction.
