ToneDex

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.
