Hi,
I’m RS520 user, love the device usability and overall audio quality for the money, but I wonder when Apple Music HiRes will be available. Apple did some upgrades on their side and now Android users can choose better than AAC audio quality so I wonder when it will come to Rose.
PS. I’d like to see less Korean in Apple Music, at least English should be the default language of choice.
Only Apple hardware or software developed by Apple products and apps support lossless music.
Since the app (software) on the Android phone was also developed by Apple, it supports lossless sound sources.
So, until now, Apple hardware or software supports only up to aac256 bps unless it is a product or app developed by Apple.
For hi-fi audio equipment, I think Apple Music will gradually expand technology disclosure.
If Apple releases this part in the future, we will be able to apply it.
If you see Korean when using Apple Music in the RoseConnect app, delete and reinstall the RoseConnect app.
Hi,
I am considering Hifi Rose, and Apple Music lossless is also important to me. I notice that Eversolo DMP-6A has Apple Music lossless. To my understanding both Hifi Rose and Eversolo use a version of Android, and I do not understand why Hifi Rose do not support lossless.
What have I missed, can you please help me understand?
As I understand, the Eversolo uses native Apple Music android app, and HiFi rose uses its own application and Apple API to receive and stream music. It is a big difference. In general, native Apple App is not easy to control from remote device (like the phone) and Eversolo has to do some thicks like app screen mirroring over wifi network to be able to control the app and its not flawless. Native HiFi Rose App , while can be controlled via the remote or phone, has no access to Lossless content via API method it uses. In theory, it could be possible to run native Android Apple music app on HiFi Rose, but we’ll have very limited way of controlling it, probably it would be accessible via front touch screen only.
That, and I think Eversolo has a more standard screen aspect ratio. Even if you could sideload native Apple Music app onto Rose, it’s not a given that it would be usable on Rose’s screen, let alone interface with the native Rose UI…
Dear Hi-Fi Rose Users
Only Apple hardware or software developed by Apple products and apps support lossless music.
Since the app (software) on the Android phone was also developed by Apple, it supports lossless sound sources.
So, until now, Apple hardware or software supports only up to aac256 bps unless it is a product or app developed by Apple.
For hi-fi audio equipment, I think Apple Music will gradually expand technology disclosure.
If Apple releases this part in the future, we will be able to apply it.
Additionally, we will explain the differences in how to play Apple Music lossless music on other products.
Hi-Fi Rose does not use the Android Audio Framework to provide HIFI Audio services but is designed to deliver pure audio data to the DAC without loss by using the self-developed Rose Audio Server.
Since we use the Android OS, there are many people who misunderstand that the Audio System also uses the Android Audio System, so I would like to explain the current audio playback structure of Hi-Fi Rose in more detail.
Basically, we use Android to provide a smooth touch screen-based user interface. Additionally, all processes related to HDMI output and graphics on the LCD are performed through the Android Framework. Android’s graphics system is very well tuned compared to other OSs, so the CPU calculations and power consumption required to provide a similar interface are relatively small. This has the advantage of minimizing interference in audio-related processing despite providing a rich graphical interface.
In addition, video playback, system settings, etc. are also used by taking advantage of Android.
The audio system does not use the Android Framework. To provide HIFI Audio service, all steps from I/O to sending audio data to DAC were implemented using the Rose Audio Server we developed ourselves.
Figure 1 is the traditional Android audio structure. A mixer is implemented on the Android Framework to support various audio channels (calls, notification sounds, multimedia, alarm etc.), and all audio is played through this mixer. Because of this, transcoding inevitably occurs in the audio data, and even when playing lossless sound sources, they are played at a specific Bit/Sampling Rate.
However, Hi-Fi Rose products do not use the Android Framework for audio playback, as shown in Figure 2.
When playing audio, only the path is passed to the Rose Audio Server, and the Rose Audio Server directly reads the audio source (file/stream, etc.), converts it into pure audio data (PCM/DSD), and uses the ALSA (Advanced Linux Sound Architecture) API. to pass audio data to the DAC on the Linux Kernel. Rose Audio Server is a framework for HiFi Audio developed directly by Hi-Fi Rose to deliver audio data as it is to the DAC without modification, support MQA Decoding, or perform DSP functions such as EQ (RS201), MQA Decoding, Resampling, etc.
I’m sorry but I really don’t understand your previous sentence:
So, until now, Apple hardware or software supports only up to aac256 bps unless it is a product or app developed by Apple.
Do your product support hi-res bitstream lossless from AppleMusic or not?!
Apple Music lossless is not available at the moment for Rose HiFi.
As the owner of RS520, which is great, I keep my fingers crossed for the future and I hope to see Apple Music hires as it is on Eversolo and FiiO with some clever tricks.
