Abstract: Embodiments of the present disclosure describe a call recording system and a call recording method for automatically recording, i.e. storing, a call candidate when an active call is detected. The call recording system comprises a sound receiver to receive sound data and to convert sound data to audio representations of sound, a buffer to buffer the audio representations of sound for a predetermined time duration, a call candidate determination unit to determine if the buffered audio representations comprise a call candidate, a call analyzer to analyze the call candidate, wherein the call analyzer determines if the call candidate is a call to be stored, and a storage to store the call candidate as a call. Hence, a reliable system can be provided for automatically storing a call.

Abstract: An audio interface device, comprising: an interface unit and a wireless unit, wherein the interface unit is configured to relay a first audio signal transmitted between a microphone and a communication device and a second audio signal transmitted between the communication device and a speaker, and to route first audio data related to the first audio signal and second audio data related to the second audio signal to the wireless unit; and wherein the wireless unit is configured to transmit the first audio data and the second audio data to a remote audio device.
