  • Publication number: 20220264223
    Abstract: A sound signal processor and a control method therefor that enable appropriate processing to be applied to each sound signal and the sound signals to be outputted to an appropriate output destination, while avoiding equipment connection complexity. A first processing unit performs first processing on a first sound signal to generate a second sound signal, and outputs the second sound signal to a mix bus, a second processing unit performs second processing on a third sound signal to generate a fourth sound signal, and outputs the fourth sound signal to the mix bus and a first output destination, and the mix bus mixes the second sound signal with the fourth sound signal to generate a fifth sound signal, and outputs the fifth sound signal to a second output destination.
