I'm trying to use OpenSL ES for Android in my project in order to provide a low-latency and I found that NDK sample NativeAudio is designed only for recording a short snapshots.

Could you please advise me, where can I find a samples of how to record audio with a long duration? Thanks in advance.

the native-audio sample is updated to playback in low latency path; a new sample audio-echo is created to loop back audio in low latency path on Android.
