The musical gift box is a container uses to store jewelry. The musical gift box rotates between a closed position and an open position. The musical gift box incorporates a jewelry box, a control circuit, and a personal data device. The jewelry box contains the control circuit. The control circuit forms a wireless communication link with the personal data device. The jewelry box is a rotating structure. The jewelry box contains the jewelry. The jewelry box rotates between the closed position and the open position. The control circuit detects when the jewelry box is in the closed position. When the jewelry box rotates towards the open position, the control circuit: a) establishes the wireless communication link with the personal data device; b) receives a transmission from the personal data device containing a music file; and, c) converts the music file into an audible sound commonly referred to as music.

Systems and methods for fast activation of slaves during wake up in an audio system allow a master device in an audio system such as a SOUNDWIRE audio system to send system and/or topology information to capable slave devices during a wake up window so that the slaves may start in an active mode rather than a safe mode. In the most recent proposed versions of SOUNDWIRE, there is a check PHY_Num phase. The systems for fast activation of slaves cause a negative differential line to be driven with an encoded signal by the master during a check PHY_Num phase where the encoded signal indicates a fast mode speed. Capable slaves may then begin in a fast mode rather than a safe (and slow) mode. Latency may be reduced by starting in a fast mode, which may improve the user's audio experience.

Example techniques relate to calibration interfaces that facilitate calibration of a playback device. An example implementation may involve outputting a sequence of prompts to guide calibration of a playback device during a calibration sequence comprising (i) a spatial calibration component and (ii) a spectral calibration component. Outputting the sequence of prompts includes outputting one or more first audio prompts representing a guide to perform the spatial calibration component of the calibration sequence. The spatial calibration component involves calibration of the playback device for a particular location within an environment. Outputting the sequence of prompts also includes outputting one or more first second prompts representing a guide to perform the spectral calibration component of the calibration sequence. The spectral calibration component involves calibration of the playback device for the environment.
