InTuneNation のアプリ分析 9月5日

InTuneNation analyzes your scale recording and shows note‑by‑note intonation stability (in cents). See which notes drift, review the waveform, and export a PDF report to track progress over time. HOW IT WORKS 1. Pick a scale (major, minor, harmonic, melodic - 1 to 4 octaves) 2. Record yourself playing 3. Get a per-note stability scorecard with clear tiers: Excellent, Good, Developing, or Unsteady 4. Tap any note for detailed metrics and interpretation FEATURES - Works with any pitched instrument: violin, voice, brass, woodwinds, piano, guitar - Automatic detection of sustained vs. percussive sources - metrics adapt accordingly - Supports A=440/441/442/443 Hz reference pitches - Transposing instrument support (Bb, Eb, F instruments, octave transposers) - Sharps/flats notation preference - Export recordings (.m4a) or PDF analysis reports to share with a teacher - Playback your recording with pitch overlay to see exactly where notes landed - Reference tone playback (pure sine or synth violin) at adjustable tempo DESIGNED FOR HONEST FEEDBACK InTuneNation won't give you an "Excellent" unless you earned it. Thresholds are based on what professional musicians actually achieve - not feel-good numbers. PRIVACY FIRST - No account required - No tracking or analytics - All analysis happens on-device - Your recordings stay on your phone unless you choose to export Built for serious practice, not gamification.
