DTA (Direct Transport Audio) Architecture

1. The HiByMusic DTA Architecture circumvents Android sample rate conversion on a system level to reliably product completely lossless audio streams on Android;

2. The preinstalled HiByMusic app may directly output DSD512, PCM768kHz / 32bit and MQA at 16x unfold; DTA provides the groundwork for all 3rd party apps to output at these same formats and rates but certain 3rd party apps may not be able to do so, owing to limitations inherent in the app (e.g. assuming the system is unable to output at those formats / rates and resampling internally before handing out audio to system).
