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.

A phone app is disclosed that enables a user to place 3D sound in a room. The user of this app is able to locate precisely where sound is perceived to originate by aiming their phone. This app may be used by audio professionals in place of the controls on a traditional sound mixer.

This control device for an electronic percussion instrument inputs a musical sound signal corresponding to a hit on a struck surface to a first amplifier for amplifying a signal to be connected to a first speaker disposed on the back side of or around the struck surface, and inputs the musical sound signal to a second amplifier for amplifying a signal to be connected to a second speaker disposed on the back side of or around a first struck surface at a timing later than a timing at which the musical sound signal is inputted to the first amplifier.

A transmission apparatus includes a first transmission unit that transmits sound data to a first sound channel in a transmission path, and a second transmission unit that transmits meta data related to the sound data to a second sound channel in the transmission path while ensuring synchronization with the sound data.

An audio signal output system including a first audio signal path, a second audio signal path and control electronics that provide a mixed sound from sound sources to the first and second audio signal paths, and control the mixed sound in accordance with a position at which a sound image associated with at least one of the sound sources is localized relative to an orientation of a user's head. The control electronics provide one or more signals corresponding to the mixed sound to the first and second audio signal paths based on one or more transfer functions associated with one or more values corresponding to at least one of a distance from the user to the at least one sound source, an angle of the user with respect to the at least one sound source, and a size of a space in which the user is located.

A system including: an electronic memory device and a processor. The processor is configured to: control a communication device to receive first input information indicating a first instruction, the first instruction corresponding to control of sound associated with at least one first sound source; control a transmitter of the communication device to transmit first information to an audio output device, the first information corresponding to the first input information indicating the first instruction; control the communication device to receive second input information indicating a second instruction corresponding to control of sound associated with the at least one second sound source; and control the transmitter to transmit second information to the audio output device, the second information including or corresponding to an audio signal associated with the at least one second sound source and processed according to the second input information indicating the second instruction.

A video game includes an audio-video stream combined with game graphics and game sounds. The game graphics are overlaid on the video stream and updated in synchronization with the stream. Update of the game graphics and sounds depends on inputs received from a game player. The game player may provide input using a game controller coupled to the video game by an adapter. The video game may play on a Blu-ray player.

The sound signal processing method includes obtaining a sound signal of a sound source, convolving, according to a location of the sound source an impulse response of an early reflection sound with the sound signal to generate an early reflection sound control signal that reproduces an early reflection sound, and convolving an impulse response of a reverberant sound with the sound signal to generate a reverberant sound control signal that reproduces a reverberant sound.

A guitar pedalboard for creating a loop includes a touch screen display for displaying a plurality of tracks of a loop. The touch screen display can be used to adjust a parameter of each track, and the loop. A plurality of footswitches corresponding to the plurality of tracks can be used to independently record and play each track of the loop.
