Disclosed herein, among other things, are methods and apparatus for providing a time-stamp based controller for synchronization of sink or source sampling rate with external packet rate. A method for wireless communications includes receiving a transmission of a packet using a wireless transceiver of an electronic device, and using a processor of the electronic device to read a first value of a system timer and store the first value as an arrival time-stamp. The packet is decoded and processed by the processor, and sent to an output. When the processed packet is sent, a second value of the system timer is read, adjusted and stored as a departure time-stamp. The arrival time-stamp and the departure time-stamp are used to calculate an adjustment stimulus for a sample rate actuator of the electronic device. The sample rate actuator is configured to maintain synchronization of sampling rate with an external packet rate.

A wireless communication device includes an information wireless communication unit configured to transmit control information by a first wireless communication method; a sound signal transmission unit configured to transmit a sound signal by a second wireless communication method; and a selection controller configured to select any one or both of a first transmission processing of transmitting the control information from the information wireless communication unit by the first wireless communication method and a second transmission processing of embedding the control information in the sound signal and transmitting the control information from the sound signal transmission unit by the second wireless communication method.

Aspects of embodiments pertain to a method for determining an Input/Output (I/O) device configuration for a music teaching system. The method may comprise receiving a plurality of I/O device configurations of a music teaching system; receiving, for a given I/O device of the music teaching system, an initial I/O device configuration; and determining an updated I/O device configuration for the given I/O Device, based on the initial I/O device configuration of the given I/O Device and at least one of the plurality of received I/O device configurations. The determining is performed such that the updated I/O device configuration has improved device performance compared to the initial I/O device configuration.

A human interface device including a processor coupled to a memory. A plurality of switch banks, also coupled to the processor and a rotary dial and a slider, both coupled to control circuitry, said control circuitry operable to provide positional information from the dial and the slider to the processor. The rotary dial and slider are disposed on the human interface device to form an association with the switch bank, a drive transducer coupled to said processor, said drive transducer including a plurality of LED sources spatially positioned on a positioning ring, a set of non-transitory processor instructions operable to direct the processor to provide MIDI commands through a BLE port.

A method for online music learning of playing a musical instrument, that may be a string instrument, a woodwind instrument, a brass instrument, a percussion instrument, or vocal (singing) is described. A client device, such as a smartphone or a tablet notifies a person, such as visually by a display or audibly by a sounder, of a sequence of musical symbols that may be part of a musical piece to be played on the musical instrument. The pace or tempo of the notified sequence is adapted according to a stored skill level value of the person and the pace or tempo associated with the musical piece. The client device, monitors, using a microphone(s) in the client device, the errors in the playing of the sequence, and using a predefined accordingly updates the stored skill level value, and accordingly changes the arrangement, pace and/or tempo of the next sequence of musical symbols.

A method for adapting auditory biofeedback cues to adjust a user's gait includes receiving a series of respective first signals from each sensor of an integrated sensor system and converting the series of respective first signals into a series of respective second signals. Each respective second signal within the series of respective second signals can be quantized as an audio biofeedback cue and modified so the timing of each respective second signal is aligned to a pre-selected temporal or musical grid. The user's gait is then analyzed as a function of the audio biofeedback cues and the pre-selected temporal or musical grid can be adapted to adjust entrainment of the user's gait.

Wirelessly programmed and controlled switching system for use with stringed musical instruments (e.g., guitars) to enable a user to seamlessly change pickup coil settings without having to adjust the physical connections between the switch and the pickups.

Systems, apparatuses, and methods are described for a dynamic network identification to facilitate a selection of a desired audio. A premises (e.g., a public bar) may have a plurality of display devices (e.g., television screens) outputting videos associated with a plurality of content items (e.g., television programs). A computing device may assign an audio data of each of the content items to be transmitted over a separate wireless network. A user may be able to listen to the audio of a desired content item by causing a user device to join a wireless network assigned to transmit an audio data of the desired content item. The wireless network may be reused to transmit a different audio data. A network identifier of the wireless network may be renamed to indicate the different audio data. The network identifier may be based on metadata associated with a content item.

A method of processing textual and graphical feedback of a virtual audience of a performance for compensating and providing sonic cues to the performers through monetizing and audially representing, respectively, the textual and graphical feedback.

A communication device for an electronic musical instrument includes a battery; an input terminal that is connected to a MIDI output terminal of the electronic musical instrument; an output terminal that is connected to a MIDI input terminal of the electronic musical instrument; a control unit that transmits and receives various kinds of electronic information between the electronic musical instrument and the other electronic instrument via the input terminal and the output terminal; and a switching unit that switches between taking in electric power to be supplied to the control unit through a MIDI signal line from the electronic musical instrument via the input terminal and taking in the electric power from the battery in accordance with a communication state of the control unit.
