摘要：
An audio watermark signal is associated audio host signal, but is provided separately. When the audio host signal is rendered, a user can control whether—and how strongly—the watermark signal is also rendered. The specification details a great variety of other technologies—most relating to audio and image content, and/or portable devices (e.g., smartphones).
