MuSA_RT vs ToneDex

MuSA_RT applies music analysis algorithms rooted in Elaine Chew’s Spiral Array model of tonality, which also provides the 3D geometry for the visualization space. The app analyzes the audio signal received from a microphone to determine pitch names, maintain short term and longterm tonal context trackers, each a Center of Effect (CE), and compute the closest triads (3-note chords) and keys as the music unfolds in performance. The 3D view presents a graphical representations of these tonal entities in context, smoothly rotating the virtual camera to provide an unobstructed view of the current information. These graphics can also be visualized in an experimental Augmented Reality mode on compatible devices.

ToneDex can see the pitch stability(Tuner). ToneDex can analyze the sound using 5 key parameters: RMS (Loudness/Power) ZCR (Noise / Breathiness) Spectral Centroid (Brightness / Sharpness) Bandwidth (Timbre Spread) Brightness Index (High-frequency emphasis) ToneDex is designed especially for wind and acoustic instrument players who want to explore differences in setup, technique, or equipment (e.g., mouthpieces, reeds, embouchure). While originally designed for saxophone comparison, it can be used for any monophonic instrument that produces steady tones. If you're trying out new mouthpieces, comparing tone qualities, or simply want a fresh perspective on your sound, ToneDex offers a structured and visual way to reflect on your tone.
