Vocal Pitch Recorder

About

Vocal Pitch Recorder turns your phone into a visual singing coach. Sing into your microphone and watch your pitch drawn across a musical scale in real time. After recording, review each take with detailed offline analysis so you can see what you actually sang — not just a rough estimate. Perfect for singers, vocal students, karaoke fans, songwriters, and voice coaches who want clear feedback between lessons or rehearsals. KEY FEATURES • Real-Time Pitch Graph See your voice plotted note by note on a musical scale as you sing. • High-Accuracy Offline Analysis Each recording is re-analyzed after capture using a rigorous YIN-based pitch detection process with smoothing and octave-error correction. • Project-Based Practice Organize recordings by song, set BPM, add notes, and compare multiple takes over time. • Backing Track Support Load an audio file from your device and sing over it while your voice is recorded separately. • Detailed Take Summary Review min, max, and average frequency, note names, voiced ratio, duration, and other useful stats. • Interactive Pitch Review Scrub through time, zoom into difficult phrases, and switch between English note names such as C4 and Japanese note names such as ド4. • Flexible Vocal Controls Choose your microphone, adjust input gain, and set the pitch range that fits your register. • Private by Design Your audio and pitch data stay on your device. No account, no cloud upload, no tracking. Vocal Pitch Recorder helps you practice with evidence, not guesswork. Use it to check pitch accuracy, expand your range, prepare for auditions, improve karaoke performance, or capture melody ideas. Requires microphone access. Earphones are recommended when using backing tracks.
