--- title : " ARM NEON SIMD for Real-Time Audio on Android NDK" published : true description : " Cut Android audio latency below 10ms using ARM NEON SIMD intrinsics, lock-free ring buffers, and vectorized FFT in the NDK native pipeline." tags : android, mobile, architecture, performance canonical_url : https://blog.mvpfactory.co/arm-neon-simd-real-time-audio-android-ndk --- ## What We Will Build In this workshop, I will walk you through a native audio pipeline on Android that consistently delivers sub-10ms round-trip latency. You will learn how to configure Oboe/AAudio for exclusive low-latency streaming, design a lock-free SPSC ring buffer that won't glitch on the real-time callback thread, and vectorize your FFT butterfly operations with ARM NEON intrinsics for a 3-4x throughput gain over scalar C++.…
