GalileoTuner vs FM Playground

Galileo is a music tuner. Earth mode shows the pitch by chromatic scale in circle.(Please set the microphone on). Jupiter mode shows detailed pitch in smaller circle. When the red mark in the opposite side of "50" aligns with the red arrow bellow the smaller circle, it produces equal temperament pitch. The two smaller red marks on both side of the red mark shows just intonation of major 3rd (-) and minor 3rd (+). ※For monophonic instrument

FM Playground is an educational app designed for learning and experimenting with FM synthesis (Frequency Modulation Synthesis). Developed as part of the "2025 Swift Sound - Creative Coding for Computer Musicians" project at MARTE Lab, Department of Multimedia, Dongguk University, by Yeonho Kim, Taejun Kim, Seoyul Son, and Sookyung Yoon, with guidance from Gwangyu Lee. The app features multiple interactive views where users can manipulate sound in real time using touch gestures and iPhone sensors (gyroscope, compass, etc.). Key Features: - What is FM Synthesis?: Learn the fundamentals of FM synthesis with an interactive view. Adjust sliders to hear real-time modulation effects and explore complex timbres. - Gesture-based control of timbre, frequency, and volume across various interactive views. - Open-source code available for study, experimentation, and expansion.
