To solve this, the APK cannot rely on real-time waveform display; instead, it must implement a block-processing pitch detection algorithm . The YIN algorithm, a variant of autocorrelation, is ideal here. It requires minimal heap allocations—critical on Jelly Bean’s Dalvik VM, which suffers from garbage collection stutter. The app must read raw PCM data, apply a Hann window to reduce spectral leakage, and feed the signal into a lightweight FFT (Fast Fourier Transform) library written in C via the NDK (Native Development Kit).
