Abstract
A sound signal conversion device includes a supplier. The supplier supplies a periodic change to an input sound signal and outputs the sound signal to which the periodic change is supplied. The supplier includes a phase determiner that determines a phase at which the periodic change supplied to the sound signal starts based on initial phase information when receiving a start instruction for starting supply of the periodic change to the sound signal.
Claims16
A sound signal conversion device comprising:
- a supplier that supplies a periodic change to an input sound signal and outputs the sound signal to a speaker to which the periodic change is supplied, wherein
- the supplier includes a phase determiner that determines a phase at which the periodic change supplied to the sound signal starts based on initial phase information when receiving a start instruction from a button for starting supply of the periodic change to the sound signal, and stops supplying the periodic change to the sound signal and updates the initial phase information based on a current phase of the periodic change with respect to the sound signal, when accepting the stop instruction, in a case where reset phase information is not provided.
A sound signal conversion method of:
- receiving a sound signal;
- accepting a start instruction for starting supply of a periodic change to the sound signal;
- determining a phase at which the periodic change supplied to the sound signal starts based on initial phase information when the start instruction is accepted, and supplying the periodic change to the sound signal;
- stopping supplying the periodic change to the sound signal and updating the initial phase information based on a current phase of the periodic change with respect to the sound signal, when accepting the stop instruction, in a case where reset phase information is not provided;
- and
- outputting the sound signal to which the periodic change is supplied.
A non-transitory computer readable medium storing a sound signal conversion program, which when executed by a computer, causes a computer to:
- receive a sound signal;
- accept a start instruction for starting supply of a periodic change to the sound signal;
- determine a phase at which the periodic change supplied to the sound signal starts based on initial phase information when the start instruction is accepted, and supplying the periodic change to the sound signal;
- stop supplying the periodic change to the sound signal and update the initial phase information based on a current phase of the periodic change with respect to the sound signal, when accepting the stop instruction, in a case where reset phase information is not provided;
- and
- output the sound signal to which the periodic change is supplied.
