ToneDex vs Audiotest (hearing_app)

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.

Check how you hear. Take a sound apart. Build a noise you have never heard. The spectrum shows what speech, music, or the quiet around you is made of. Noises stack in layers: a steady bed, a rustle, a hum. That becomes a sound scene of your own. Save it and play it again. Glide a tone from a low hum up to a thin high note and notice where it disappears. The hearing chart is saved too, so you can compare it with last time. This is for you, at home, with headphones. It is not a visit to the doctor: if your hearing worries you, see a professional.
