Data processing method of processing multitrack audio data and data processing apparatus

A data processing method that reproduces data signals of a plurality of devices that utilize different protocols from each other, the data processing method comprising:

• receiving multitrack audio data in which audio data of a plurality of channels is stored;
• and
• reproducing the received multitrack audio data by:
• reproducing a first data string stored in a first channel of the plurality of channels as a digital audio signal of a first device of the plurality of devices that utilizes a first protocol;
• and
• reproducing a second data string stored in a second channel of the plurality of channels as a digital signal, related to the digital audio signal, of a second device of the plurality of devices that utilizes a second protocol different from the first protocol,
• wherein the second data string stored in the second channel and the first data string stored in the first channel are synchronously stored in the received multitrack audio data by the digital audio signal and the digital signal having been generated according to a progress of an event and the digital signal having been stored at the same frequency as a sampling frequency of the digital audio signal.

A data processing apparatus that receives data signals from a plurality of devices that utilize different protocols from each other, the data processing apparatus comprising:

• a communication interface configured to receive data signals, respectively, from each of the plurality of devices;
• and
• a processor configured to generate multitrack audio data in which audio data of a plurality of channels is stored,
• wherein to generate the multitrack audio data in which the audio data of the plurality of channels is stored, the processor is configured to:
• store a first data string of a digital audio signal, received from a first device of the plurality of devices that utilizes a first protocol, in a first channel of the plurality of channels;
• and
• store a data string of a digital signal, related to the digital audio signal and received from a second device of the plurality of devices that utilizes a second protocol different from the first protocol, as a second data string of the digital audio signal in a second channel of the plurality of channels,
• wherein the data string of the digital signal, related to the digital audio signal and received from the second device of the plurality of devices that utilizes the second protocol different from the first protocol, in the second channel is synchronously stored with the first data string of the digital audio signal, received from the first device of the plurality of devices that utilizes the first protocol, in the first channel in the generated multitrack audio data by generating the digital audio signal and the digital signal according to a progress of an event and storing the digital signal at the same frequency as a sampling frequency of the digital audio signal.
