A method and a system for instrument separating and reproducing for a mixture audio source is provided. The method and/or the system includes inputting selected music into an instrument separation model for extracting features therefrom, determining audio source signals of multiple channels for the separation of all instruments, each channel containing sound of one instrument, and transmitting the signals of the different channels to multiple speakers placed at designated positions for playing, which can reproduce or recreate an immersive sound field listening experience for users.

A sound controlling system including a user terminal having a sound source, a wireless communication device, a digital to analog converter (DAC) and first processing electronics. The first processing electronics are configured to: provide data of a backing sound to the sound source; control the sound source to generate a sound signal based on the data; receive a first input instruction including a first instruction to transmit the sound signal and a second instruction to play back the backing sound; provide the sound signal to the wireless communication device as the first input instruction being the first instruction, and provide the sound signal to the DAC as being the second instruction; control the wireless communication device to convert the sound signal to a wireless signal and transmit the wireless signal; and convert the sound signal from a digital signal to an analog signal for play back of the backing sound.

Various implementations include portable speakers with detachable wireless transmitters. In some particular aspects, a portable speaker includes an enclosure housing: at least one electro-acoustic transducer for providing an audio output, a processor coupled with the at least one transducer; an audio input module coupled with the processor for receiving audio input signals; and an input channel for receiving a hard-wired audio input connection at the enclosure; at least one wireless transmitter detachably housed in the enclosure and in communication with a corresponding wireless input channel for receiving audio input from a source device.

Provided are a control device, a control method and a control system. In a control system, a headphone and a pedal device are in communication with each other through first communication, and the pedal device and a portable terminal are in communication with each other through second communication. Accordingly, even when the headphone can be connected to only one control device, a control instruction from the pedal device can be transmitted to the headphone through the first communication, and a control instruction from the portable terminal can be transmitted to the headphone through the second communication and the first communication.

A portable digital audio system for a musician. The digital audio system includes an amplifier for processing an audio signal from a musical instrument or microphone electronically connected to the digital audio system and a speaker for playing a sound associated with the audio signal processed by the amplifier. The portable digital audio system also includes an audio control system providing operational control of the digital audio system and a primary housing for supporting the amplifier, the audio control system, and the speaker. Further, the digital audio system has a touch screen display in electronic communication with the audio control system and supported by the primary housing.

A pedal device receives a connection signal transmitted from headphone to establish first communication that is communication with the headphone. Then, in a case where the first communication has been established, the pedal device transmits the connection signal including information indicating that communication with the headphone has been established. By receiving the connection signal from the pedal device, a portable terminal establishes second communication that is communication with the pedal device. In a case where the received connection signal includes information that the communication with the headphone has been established, the portable terminal may determine that communication establishment between the pedal device and the headphone has been completed.

The presence of saxophonists furthering their musical horizons by playing keyboard instruments inspires the invention of a novel device to connect a light-weight keyboard or MIDI grid controller to a saxophone to facilitate the convenient and rapid switching between playing either instrument. Battery power and Bluetooth technology combine with innovations in plastics technology to facilitate the creation of strong, lightweight structures to facilitate such a device. With the addition of looping software on a laptop computer, a saxophonist so equipped can create music to accompany themselves, obviating the need for other musicians to function as a musical ensemble. This innovation may be the harbinger for other musicians on other single note instruments—trumpet, trombone, violin, etc. to join this trend using either instrument-attached, strap-on or wearable keyboards. This could blend the boundaries between acoustic and electronic instruments, and increase the enjoyment and musical enrichment of musicians and audiences alike.

The present disclosure relates to a virtual drum kit device. The virtual drum kit device includes a motion capture device and a drum sound processing device separated from each other; where, the motion capture device includes at least two drumsticks, the drumstick including a first cover body, as well as a first battery, a first control printed circuit board assembly (PCBA) board and a vibration motor which are arranged in the first cover body, the first control PCBA board being connected to the battery and the vibration motor separately, and being capable of transmitting an RF signal to the drum sound processing device according to a motion instruction captured by the drumstick, the drum sound processing device includes a second cover body, as well as a second battery and a second control PCBA board which are arranged in the second cover body.

A system and method is disclosed for identification of a musical note played by a musical wind instrument with a resonant chamber having a plurality of configurations selectable by a player of the musical wind instrument and an electrically conductive surface in the resonant chamber. The system and method include a stimulation signal generator for generating a stimulation signal and antenna means mountable on the musical instrument for broadcasting the stimulation signal as an electromagnetic signal within the resonant chamber and for receiving a reflected electromagnetic signal from the resonant chamber The system and method also include an electronic processing unit for processing the reflected electromagnetic signal and determining therefrom a configuration of the resonant chamber selected by the player and indicative of a musical note that is or would be output by the instrument when played at the time of the received reflected signal.

Systems and methods for creating a digital audio filter, such as an impulse response filter, using a pickup audio signal provided to an instrument signal capture device and a microphone signal provided to a mobile device are disclosed. In one embodiment, a method includes capturing a first audio signal using a signal capture device, performing frequency analysis on the digitized first audio signal to generate a frequency response spectrum representation, transmitting the frequency response spectrum representation of the first audio signal from the signal capture device to a mobile device, capturing a second audio signal using a microphone on the mobile device, performing frequency analysis on the at least one digitized second audio signal using the mobile device to generate a frequency response spectrum representation, and generating a digital audio filter from the frequency response spectrum representations of the first audio signal and the second audio signal.
