摘要： An acoustic device includes an audio recording playback unit, an analysis unit, and an acoustic effect imparting unit. The audio recording playback unit records and plays back string independent acoustic signals for each string independent acoustic signal. The string independent acoustic signals respectively correspond to different strings of a stringed instrument and being independent from each other. The analysis unit analyzes at least one string independent acoustic signal from among the recorded string independent acoustic signals. The acoustic effect imparting unit imparts an acoustic effect to the at least one string independent acoustic signal for each string independent acoustic signal, based on a result of the analysis by the analysis unit.
