Click *Run/Run 'app'*. + +Usage +----- +App will capture audio from android devices and playback on the same device; the playback on speaker will be captured immediately and played back...! So to verify it, it is recommended to "mute" the playback audio with a earspeaker/earphone/earbug so it does not get looped back. Some device like Nexus 9, once you plug in an external headphone/headspeaker, it stops to use onboard microphone AND speaker anymore -- in this case, you need turn on the microphone coming with your headphone. Another point, when switching between external headphone and internal one, the volume is sometimes very low/muted; recommend to increase the playback volume with volume buttons on the phone/pad after plugging external headphone. + +Low Latency Verification +------------------------ + +1. execute "adb shell dumpsys media.audio_flinger".

All audio processing has to be completed in the time period they are captured / played back, plus extra time needed for: + * audio driver + * audio flinger framework, + * bufferqueue callbacks etc +Besides those, the irregularity of the buffer queue player/capture callback time is another factor. The callback from openSL may not as regular as you assumed, the more irregularity it is, the more likely have choopy audio. To fight that, more buffering is needed, which defeats the low-latency purpose! The low latency path is highly tuned up so you have better chance to get more regular callbacks. You may experiment with your platform to find the best parameters for lower latency and continuously playback audio experience. +The app capture and playback on the same device [most of times the same chip], capture and playback clocks are assumed synchronized naturally [so we are not dealing with it] + +Credits +------- + * The sample is greatly inspired by native-audio sample + * Don Turner @ Google for the helping of low latency path + * Ian Ni-Lewis @ Google for producer/consumer queue and many others + +Support +------- +If you've found an error in these samples, please [file an issue](https://github.com/googlesamples/android-ndk/issues/new). + +Patches are encouraged, and may be submitted by [forking this project](https://github.com/googlesamples/android-ndk/fork) and +submitting a pull request through GitHub.
