[−][src]Struct oboe_sys::oboe_DefaultStreamValues
On API 16 to 26 OpenSL ES will be used. When using OpenSL ES the optimal values for sampleRate and framesPerBurst are not known by the native code. On API 17+ these values should be obtained from the AudioManager using this code:
// Note that this technique only works for built-in speakers and headphones.
AudioManager myAudioMgr = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
String sampleRateStr = myAudioMgr.getProperty(AudioManager.PROPERTY_OUTPUT_SAMPLE_RATE);
int defaultSampleRate = Integer.parseInt(sampleRateStr);
String framesPerBurstStr = myAudioMgr.getProperty(AudioManager.PROPERTY_OUTPUT_FRAMES_PER_BUFFER);
int defaultFramesPerBurst = Integer.parseInt(framesPerBurstStr);
It can then be passed down to Oboe through JNI.
AAudio will get the optimal framesPerBurst from the HAL and will ignore this value.
