Direct Transport Audio architecture for lossless digital audio on Android

1. DTA (Direct Transport Audio) is the name of HiBy’s full-time bitperfect android audio framework;  it bypasses Android’s sample rate conversion by modifying its audio stack to output bitperfect audio;2. The HiByMusic app bundled with the R6 III may bitperfectly output up to and including DSD512 / PCM 768kHz/32bit, however many third party apps assume bad Android resampling and will conduct “high quality” resampling internally, in which case it is impossible to obtain bitperfect audio from such apps despite DTA.
