[REQUEST] A new AudioEngine sink for AAudio API for Pro Audio - Hedda - 2017-05-29
AAudio is a new Android C API introduced in the Android O preview release. It is designed for high-performance audio applications that require low latency. Apps communicate with AAudio by reading and writing data to streams.

Assume that Kodi needs a new AudioEngine sink to utilize this on Android 8.0 "O" (Oreo?)?

Why? Well first you have the new gaming features inside Kodi with RetroPlayer which could use a low-latency API for audio.
Another example to get high fidelity audio output when not bitstreaming, like when using Audio DSP addons. As DSP adds latency. Using a low-latency API could compensate for that.

AchimTuran vision is for Kodi to get native high fidelity audio output without bitstreaming.

For reference, the same discussion for SPMC: https://github.com/koying/SPMC/issues/901
Obviously, same question: What's the point of a low-latency, PCM-only new sink for a media player...
Note that it's nothing revolutionary, either. OpenSL ES in Android is already supported since a long time (https://developer.android.com/ndk/guides/audio/opensl/getting-started.html) and is at least a standard.

Not every audio algorithm introduces delay.
Is audio delay currently an issue from RetroPlayer? To be honest never really used it. I guess if we would have a delay we should try to fix this first with some adaptions to AE and RetroPlayer. A ~0 delay sink wouldn't help if we have a huge delay in an other stage.
