Abstract (in Japanese) (See Japanese page) 
(in English) Distortion stomp boxes are one of the acoustic devices used on electric guitars. This device has attracted the interest of many guitarists. With the development of digital signal processing technology, a variety of acoustic devices are modeled in digital signal processing. However, distortion stomp boxes are difficult to model due to their nonlinearity. Therefore, research to improve the accuracy of the distortion stomp boxes has been widely conducted. With the recent development of machine learning technology, machine learning is used for modeling of distortion stomp boxes. In this study, we propose a technique based on Long Short-Term Memory (LSTM). The learning model of the proposed technique is constructed using a structure based on the Wiener model. In this paper, after explaining the proposed technique, we compare the proposed technique with a conventional technique that also uses LSTM, and report the results.
