Feeding acoustic signals into a voice connection

摘要

The method involves providing auxiliary signals (8) of a memory (6) of a processing unit (5) equipped terminal (1). The program application (4) to be recorded in the voice call is executed by auxiliary signals through the program application due to corresponding operation of the processing unit of the terminal. The loudspeaker signals issued by a channel on a socket (9) of terminal for external speakers are mixed to form a composite signal. The microphone signals are added prior to the transmission to the terminal (18). An independent claim is included for a system for recording additional acoustic signals.
