Abstract
A system comprising audio logic adapted to convert captured sound into an audio signal. The system also comprises transmission logic which causes noise to be added to the audio signal. The system further comprises processing logic adapted to at least partially remove the noise from the audio signal by subtracting a noise waveform from the audio signal to produce a result signal. The processing logic generates the noise waveform using power level information associated with the transmission logic. The transmission logic transmits the result signal to another electronic device.
