Low latency Audio - because your ears are worth it
summary
Demonstrates the Oboe C++ library for low‑latency audio, using AAudio on API 27+ and OpenSL ES on older devices, and shows exact choices: request exclusive sharing mode to shave milliseconds, set buffer to double the frames‑per‑burst to avoid underruns, implement an onAudioReady callback that fills float frames, and tie rotation sensor values to oscillator frequency. Builds a simple musical instrument on a Pixel XL, it runs live and sounds responsive, and plays over the Amen break loop.
