Abstract
An audio system includes a first audio device and a second audio device. The first audio device receives an operation of increasing or reducing a parameter value, controls a first parameter using control amount according to operation amount, calculates a ratio of change in the control amount relative to a whole parameter adjustment range, and transmits the ratio of change to the second audio device. The second audio device receives the ratio of change, converts the ratio of change into a control amount of whole parameter adjustment range, controls a second parameter using a value of an integer part of the control amount, integrates the value of the fractional part of the control amount in a storage unit, and controls the second parameter using the value of the integer part when integer part is generated in the integrated value of the storage unit.
