Из интересного Direct Transport Audio (DTA). Если коротко, они переработали архитектуру Android касающуюся вывода звука для приложений. Обещают bit-perfect для всех аудио приложений. Детальнее тут (на английском):

Спойлер: 

What HiBy has achieved, on the other hand, is a custom Android architecture that supports bit-perfect non-resampling output from all apps, as long as the app itself lays its hands off audio resampling. We call this the Direct Transport Audio architecture (DTA).

Before DTA, you had essentially 3 classes of audio apps with the following behaviour (excluding bundled audio apps with special privileges):
1. Apps that didn't give a whit about digital audio quality on its end, trusting Android with it (majority of apps): audio gets sent as is to the Android audio stack where it is digested and sent back out at the "native sample rate" of the device (usually 48kHz, but 44.1kHz is also common), along with a bit more messing about with track mixing.
2. Apps that cannot bypass the resampling process but nevertheless want to have control over the quality, by resampling the audio on its end before sending it to Android: audio gets resampled by the app's (presumably premium) resampling processes before being sent to Android. Audio mixing is still an issue.
3. Apps that utilize various more-or-less proprietary methods employed by different ROMs to bypass resampling. These apps produced bit-perfect output on supported devices, which unfortunately more often than not tended to be smartphones rather than DAPs with their special architectures. There were also quite few of these apps.

With the advent of DTA, the landscape changes for all these apps:
Class (1) is where the most of the action takes place, because we have takena apart the standard Android audio stack and turned it around its head, making it work bit-perfectly with no resampling taking place. Hence many, many apps previously expected to be of throwaway quality become bit-perfect transports. This includes streaming apps like Tidal and such, giving you maximum benefit from high-res lossless streaming.

Class (2) unfortunately benefits less from the new architecture, because DTA must still report a "device standard" sampling rate, even though it is in fact not tied down to any particular rate: these apps would take the superfluous step of resampling to 48kHz before sending it to DTA, where it nevertheless benefits from the removal of mixing processes.

Class (3) also benefits from DTA, because we have taken every step necessary to make it compatible with the other bit-perfect hacks used on the Android market before.
