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?
Solution
OpenSL ES:
Advantages:
- Low Level Audio API in Android
- Device Independent on Android Phones
- Good for Gaming
Disadvantages:
- Supports only on 2.3+ os
AudioTrack:
Advantages:
- High Level API
Disadvantages:
- Works on Java layer and Native code has to call javalayer to play audio.
