Lots o’ kudos for the Headphone Bar (Vancouver BC) for getting it into the outgoing mail late Wednesday and for Canada Post for delivery to St John’s 4 days early in spite of bad weather.Ĭurrently listening to Fleetwood Mac’s “Rumours” (192kHz), and via JRemote it sounds great, but keep in mind I can only relate to the iPhone’s own DAC and that of the Soundblaster E5.

This includes streaming apps like Tidal and such, giving you maximum benefit from high-res lossless streaming.Ĭlass (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.Ĭlass (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.10 minutes after kicking myself for not opting for expedited delivery, a text arrives letting me know my Cayin RU6 has been delivered. Hence many, many apps previously expected to be of throwaway quality become bit-perfect transports.
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. 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. Audio mixing is still an issue.Īpps that utilize various more-or-less proprietary methods employed by different ROMs to bypass resampling. We call this the Direct Transport Audio architecture (DTA).īefore DTA, you had essentially 3 classes of audio apps with the following behaviour (excluding bundled audio apps with special privileges):Īpps 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.Īpps 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. 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. Neutron? (Poweramp alpha supports high-res playback but does not support locking output frequency to source frequency)
That might not sound like much news by itself, since many devices have supported bit-perfect playback via the bundled custom designed music player or a handful of players that support it somewhat universally, such as Neutron and. Now for a bit more about the "non-destructive" business, yes it means lossless music, but here it means more than just playing back lossless music, it means piping that lossless music losslessly past Android to the DAC as well. Here's the snippet of a forum thread that could be found on and let's hope that Apple Music would belong to Class (1) as mentioned below

Other than that, let's wait and see if Windows 11 were actually allowing APKs to be sideloaded or not. In other words, lossless audio is captured by AirMusic while UAPP is receiving everything on the other end via UPnP / DLNA. UPnP / DLNA functions are available on both apps so in theory we should be able to enable loopback audio on the same Android device.

Suppose that's somehow working miraculously, right now I could only think of paying 8 bucks (got it for $5.49 recently) for USB Audio Player Pro plus another $6 for AirMusic. Systemwide Direct Transport Audio Architectureīypasses Android's sample rate conversions at the system level for bit-perfect audio output.Īnd then most likely Apple Music wouldn't allow something like this
