Isolation and modification of audio streams of a mixed signal in a wireless communication device
View Patent ↗A wireless communication device comprises a wireless communication interface, a processing system, and a user interface. The wireless communication interface is configured to wirelessly receive a mixed media signal comprising a plurality of audio streams originating from different source devices. The processing system is configured to isolate the audio streams and generate graphical representations of each one of the audio streams. The user interface is configured to display the graphical representations of each one of the audio streams and receive audio stream modification instructions from a user. The processing system is configured to process the audio stream modification instructions to generate at least one modified audio stream based on the audio stream modification instructions. The user interface is configured to display a graphical representation of the modified audio stream and audibly output a modified mixed media signal comprising the modified audio stream.
