・Because the musical tone composition of multiple instruments and singing voices such as choruses and ensembles can be viewed in real time in the form of power spectra, it is also useful for play by ear .
・By playing the pitch pipe while looking at the spectrum graph, you can hear the harmony parts and the chords of the instruments.
・Please use it for checking and practicing the sound of the harmony part of karaoke.
・You can observe the overtone components that characterize musical instruments and singing voices.
