Abstract
Methods, microphones, and systems are provided for processing sound waves. The sound waves are detected with a portable device (such as a microphone) and an audio signal representing the sound waves is generated. A security layer is applied to the audio signal within the portable device (e.g., by encrypting the audio signal), so that only authorized entities may access the audio signal. The audio signal is then outputted from the portable device to an external computer, which can remove the security layer to access the audio content within the audio signal.
