Abstract: Techniques for encoding audio data with metadata are described. In an example, a device receives audio data corresponding to audio detected by a microphone and receives metadata associated with the audio. The device generates encoded data based at least in part on encoding the audio data with the metadata. The encoding involves replacing a portion of the audio data with the metadata, such that the encoded data includes the metadata and a remaining portion of the audio data. The device sends the encoded data to an audio processing application.

Abstract: A physical contact dependent feedback device is disclosed. The device requires a battery, a feedback member, and at least one sensor attached to a circuit board. All of the components are covered by an enclosure. When the sensor senses physical contact caused by a swimmer performing a correct streamline position, the feedback member is activated. In one embodiment of the present invention, the enclosure has a plurality of protrusions positioned around an outer periphery of a cover of the enclosure and a cover positioned over the circuit board, the battery, the feedback member, and the at least one sensor. In another embodiment, the enclosure is a band.
