## What is ToneSight?

See at a glance whether you’re in tune. Singing on pitch isn’t a gift reserved for a lucky few.

You’ve listened to the backing track a hundred times, but you still can’t find the melody. It feels fine while you sing, but you want to delete the recording. After a month of practice, you still don’t know if you’ve improved.

ToneSight turns “guesswork” into a curve you can see. Sing, and the screen draws your real voice—which phrase is sharp, where you waver, and how far off you are.

From today, stop practicing by feel alone. May you find joy in music.

Who it’s for
· Music lovers who want to sing a song accurately
· Voice students, exam prep, or choir practice
· Guitar, bass, or ukulele players
· Parents and teachers helping children learn songs
· Anyone who wants to know how they really sound

◆ Real-time pitch detection
Sing into your phone and watch the pitch curve move with your voice. See in real time whether you’re sharp, flat, steady, or wavering.

◆ Draw your own pitch reference
Turn the song you want to learn into a target curve: draw it manually, hum it once to generate automatically, or start from the built-in library. The curve overlays the screen, and you’ll know the instant you drift off.

◆ Lyrics follow the curve
Import lyrics and the text is arranged along the pitch curve. Sing along without getting lost.

◆ Real-time monitoring
Wear headphones and hear your real voice while you sing. Notice anything off immediately.

◆ Instrument tuner
A needle-style tuner ready to use. Presets for guitar, bass, ukulele, mandolin, violin, cello, and more, plus a dedicated six-string view.

◆ Metronome
Time signatures, subdivisions, rhythm patterns, and automatic tempo training. Tap the rhythm patterns to test your timing accuracy, stability, and early or late hits. Share the report after practice.

◆ Recording playback & pitch diagnosis
Every session is saved. Review the curve and read a report you can understand: average deviation, stability, note onset speed, and voicing ratio. It tells you the exact second of your worst phrase so you can focus there.

◆ Progress curve
Automatic scoring and logging after every session. View trends for 7 days, 30 days, or all time. Your streak helps you build the habit.

◆ Vocal range test
Open the mic and glide your voice up and down to measure your lowest and highest steady notes. It determines your voice type, gives practice suggestions, and generates a shareable certificate. History shows your expanding range.

◆ Rhythm test
Tap along with the beat and measure timing accuracy, average deviation, and stability. The data tells you whether you’re a rhythm master or need more work.

◆ Decibel meter
Check how noisy the room is, whether your practice space is quiet enough, and how loud your voice is. Includes real-life comparisons and a spectrum graph.

◆ One-tap share & export
Pitch reports, rhythm reports, and range certificates become shareable images. Export curves as MIDI, or package them for a friend to practice over.

Your voice belongs to you alone.
All analysis happens on your phone. No uploading, no internet connection, no account required.

### 26.9.2 — 2026-09-04

ToneSight 26.9.2 Update Notes

1. Practice Review & Analysis System (New)
- New post-practice diagnostics: automatically analyzes the entire practice session after recording, pinpoints the weakest segment, and provides breath and vocal production insights based on loudness and onset.
- New sustained-note breath assessment (duration / drift / flatness / loudness decay), and vibrato analysis (rate and depth) — previously vibrato could only be synthesized, now it can be measured.
- Enhanced progress curve: history is now stored in segments; scoring model upgrades automatically calibrate and show “Scoring model calibrated.”
- Recording list adds sorting / filtering / search: sort by duration, pitch deviation, or phonation ratio; filter by sharp or flat.

2. Pitch Scoring Improvements
- Scoring without a reference layer: recordings now receive automatic scoring even when no reference layer is overlaid (based on twelve-tone equal temperament), with optional key-constrained scoring (measures against diatonic notes in the current key and identifies out-of-key wrong notes).
- Reference scoring model fixes: RMSE and standard deviation are now semantically separated; added signed mean cent deviation and pitch tendency display (overall sharp / flat / centered), with backward compatibility for older recordings.

3. Sound Level Meter
- Multi-frequency weighting support: added B / C / Z / ITU-R 468 curves, default A-weighting, selectable in the pop-up.
- Shows peak-hold residual trace.
- Spectrum bar +6 dB calibration and Fast time weighting.

4. Test Fixes (Range / Rhythm / Sound Level Meter)
- Vocal range test now uses a time sliding window + true standard deviation; single-ended measurements no longer fabricate stable values.
- Microphone startup failure can now be retried.
- Fixed rhythm report showing measure count always as 0; added touch input debouncing.

5. Reference Layer Write Protection
- Locked layers cannot be renamed or shared (TSL forwarding / MIDI export); grayed menu items show a lock icon and tooltip.

6. Home Monitoring Hero Wave Changed to Static

7. Internationalization
- New French localization; select Français in Settings.

8. Quality & Stability
- Fixed existing bugs and completed debug logging.
