BIT_PERFECT
Use bit-perfect audio decoding. This provides a theoretically pure playback experience, but requires a connected digital-to-analog converter (DAC) + a custom renderer that handles usb routing and playback of wanted format and may not work reliably on all devices.
Using this below the annotated API level is equivalent to using NATIVE.
Using this without an appropriate connected DAC is functionally equivalent to using NATIVE, but connecting an appropriate DAC will automatically cause decoding to switch to bit-perfect until it is disconnected.
