The result is an animated picture of the\nharmony, melody and tuning of whatever you play or sing.\n\nFeatures:\n\n* Real-time pitch analysis of live microphone input\n* Variable-Q Transform tuned for musical signals\n* Pitch-to-color mapping in a perceptual color space\n* Several visual modes (Full, Zen, Performance, Galaxy)\n* Tuning drift display in cents\n* Runs fully offline — no network access, no tracking, no ads\n\nPitchVis is useful for musicians, singers, music students and anyone curious about the\nstructure of the sounds around them. It works with any instrument or voice.\n\nThe app requires only the microphone permission and does not connect to the internet.\n","categories":["Multimedia","Science & Education"]}
