1. You choose Your Pitch
Your selected madhya Sa establishes the tonal reference. The same detected frequency can map to a different swara when Sa changes.
Research & Technology
How SwarPractice hears pitch.
SwarPractice listens to your voice, estimates the pitch, and shows the corresponding swara relative to Your Sa.
How it works
From sound to swara.
2. The microphone captures a short window
The app examines small slices of incoming sound while a practice session is running. It does not need to identify the singer.
3. Pitch is estimated
A signal-processing pitch detector estimates the fundamental frequency when the input is strong and periodic enough.
4. Frequency becomes feedback
The estimate is mapped relative to Sa, then shown as swara, register, cents deviation, accuracy, and stability cues.
Privacy
Your voice stays on your device.
Live pitch analysis runs on your device. Optional session recordings remain there until you share or delete them.
Limits
Pitch detection is an estimate, not a musical verdict.
Room and device
Microphone quality, distance, room echo, noise, and speaker bleed can change the result. Headphones can help during accompaniment.
Voice and technique
Breathy attacks, ornamentation, fast transitions, very low signal, and unstable or multi-pitched sound are harder to track.
Musical context
A centred frequency does not measure phrasing, rasa, style, pronunciation, or the appropriateness of a swara in a raga.
A practice aid
SwarPractice supports listening and repetition; it does not replace a teacher’s musical judgment.
