Question

Currently I’m using AudioTrack passing to it audio data from native layer to play.

It seems I can use OpenSL ES in the native layer instead of AudioTrack in Java. What are the supposed advantages OpenSL ES gives as opposed to AudioTrack?

OpenSL ES:

Advantages:

1. Low Level Audio API in Android
2. Device Independent on Android Phones
3. Good for Gaming

AudioTrack:

Advantages:

1. High Level API

Disadvantages:

1. Works on Java layer and Native code has to call javalayer to play
   audio.
