To tell the truth, the school and the Magic Sound Workshop are two different institutions, not one. Telling the truth school is an online educational institution, which provides a variety of learning courses such as art, music, literature, philosophy and social sciences. Magic Sound Workshop is a music education institution, which mainly provides music courses such as guitar, bass, drum set and singing. The courses of the two institutions are different in content and form, so they are not one institution. Telling the truth is a brand owned by Beijing Quantum Song Technology Co., Ltd., which focuses on improving personal value and aims to provide users with learning content covering many fields. Magic Sound Workshop is an intelligent dubbing product that can convert words into voices online, providing real voices of different genders and accents, and directly generating audio after inputting words.
