ABSTRACT:
This invention relates to a method by means of which more than one audio signal can be recorded in compressed form in a memory element, and to a system implementing such a method. In the system according to the invention, audio signal samples are recorded only when voice is detected in the audio signals. The system according to the invention saves memory capacity required by the recording by combining the audio signal samples when voice is detected in samples of more than one audio signal. Furthermore, an audio signal is not recorded when no voice is detected in the signal. The invention also reduces the average computing capacity needed and thus power consumption, since signal combination, or mixing, is advantageously performed only when voice is detected in the samples of more than one audio signal.
