Abstract
Communication apparatus with correct audio signal regeneration are disclosed. In one example, a communication apparatus includes a counter that counts the number of a predetermined reference clock included in one cycle of a divided signal of an audio master clock with a frequency that is equal to a product of a frequency of a sampling clock for sampling of an audio signal and a multiplier on the basis of the audio master clock, a ratio of division of the divided signal and the predetermined reference clock. A packet generator generates a packet including the counted number counted, a bit width of SD (Serial Data) conforming to an I2S standard, the frequency of the sampling clock, the ratio of division of the divided signal to the audio master clock, a frequency ratio of the frequency of the audio master clock to the frequency of the sampling clock, and the SD.
