PitchTune -- Version 1.0.0 -- iOS 17.0+
Frequently Asked Questions
How does pitch detection work?
PitchTune uses autocorrelation-based pitch detection via Apple's Accelerate framework. Your microphone input is analyzed in real-time to determine the fundamental frequency of your voice, which is then mapped to the nearest musical note.
Why is no pitch detected when I sing?
Make sure you've granted microphone permission in Settings. Sing at a normal volume — very quiet or very loud sounds may not be detected reliably. Background noise can also interfere with detection. Try singing in a quieter environment.
What note range is supported?
PitchTune detects notes from C3 (130 Hz) to C6 (1047 Hz), covering the typical vocal range for most singers. Both male and female vocal ranges are supported within this span.
Is my voice recorded or stored?
No. Audio is processed in real-time memory only and is never recorded, saved, or transmitted. PitchTune works entirely on-device with zero network requests.
How are practice sessions tracked?
When you start a practice session, PitchTune samples your accuracy every 0.5 seconds. When you end the session, it records the average accuracy, best accuracy, and duration. All data is stored locally on your device.
