1. A tactile stimulation providing device comprising:
a tactile stimulation pattern generating part configured to generate n first actuator strength values corresponding to representative values of frequency bands of first audio data and m second actuator strength values corresponding to representative values of frequency bands of second audio data; and
a tactile stimulation providing part including p actuators, the tactile stimulation providing apparatus driving the p actuators, based on the n first actuator strength values and the m second actuator strength values,
wherein the n, m, and p are integers greater than 1,
wherein the first audio data includes information on a first direction,
wherein the second audio data includes information on a second direction different from the first direction,
wherein the tactile stimulation pattern generating part includes a data converter configured to convert the first audio data and the second audio data of a time domain respectively into first converted data and a second converted data of a frequency domain,
wherein the tactile stimulation pattern generating part further includes a band representative value calculator configured to calculate the representative values of the frequency bands with respect to each of the first converted data and the second converted data, and
wherein the representative values are based on valid data which are greater than a lowest threshold value of each of the frequency bands.
