Non-transitory computer-readable medium having computer-readable instructions and system

A non-transitory computer-readable medium having computer-readable instructions such that, when executed by a processor, cause the processor to:

• provide data of a backing sound to a sound source;
• control the sound source to generate a sound signal of reproduced sound based on the data;
• receive a first input instruction selected from a plurality of available input instructions, where the plurality of available input instructions include an instruction to transmit the sound signal and an instruction to play back the backing sound from the sound signal;
• provide the sound signal to a wireless communication device in response to the first input instruction being an instruction to transmit the sound signal, and provide the sound signal to a digital to analog converter (DAC) in response to the first input instruction being an instruction to play back the backing sound;
• control the wireless communication device to convert the sound signal to a wireless signal and transmit the wireless signal upon the sound signal being provided to the wireless communication device;
• and
• convert the sound signal from a digital signal to an analog signal for play back of the backing sound upon the sound signal being provided to the DAC.

A method of controlling sound signals for production of sound, the method comprising configuring a user terminal to:

• provide data of a backing sound to a sound source;
• control the sound source to generate a sound signal of reproduced sound based on the data;
• receive a first input instruction selected from a plurality of available input instructions, where the plurality of available input instructions include an instruction to transmit the sound signal and an instruction to play back the backing sound from the sound signal;
• provide the sound signal to a wireless communication device in response to the first input instruction being an instruction to transmit the sound signal, and provide the sound signal to a digital to analog converter (DAC) in response to the first input instruction being an instruction to play back the backing sound;
• control the wireless communication device to convert the sound signal to a wireless signal and transmit the wireless signal upon the sound signal being provided to the wireless communication device;
• and
• convert the sound signal from a digital signal to an analog signal for play back of the backing sound upon the sound signal being provided to the DAC.
