1. A multi-Subscriber Identity Module (SIM) wireless communication device, comprising:
- a first communications unit;
a second communications unit;
a recording unit; and
a control unit configured to cause the first communications unit to interrupt output of a first audio output signal to a sound reproduction device and conduct a first decoded audio signal to the recording unit; and
the control unit configured to cause the second communications unit to output a second audio output signal to the sound reproduction device,wherein the first communications unit includes;
a first recording tap disposed at an input of a first post-processing unit, the first recording tap configured to conduct the first decoded audio signal to the recording unit; and
a second recording tap disposed at an output of a first pre-processing unit, the second recording tap configured to conduct a first pre-processed audio signal that is output by the first pre-processing unit to the recording unit, andwherein;
the control unit is configured to cause the first post-processing unit to interrupt output of the first audio output signal and cause the recording unit to record the first decoded audio signal via the first recording tap; and
the control unit is configured to cause the first pre-processing unit to interrupt a first audio input signal to prevent recording of the first audio input signal.
