Chord Label Estimation from Acoustic Signal Considering Difference in Electric Guitars

Our previous study has developed a chord estimation system. Depending on the guitars, however, there are problem which it would be erroneously estimated as different chords. To solve this problem, this study proposes an improved method by focusing on the performance sound estimation in signal processing. As a result, it is found that the differences between the kinds of guitars are reduced using the method to be proposed in this study.
