USB Audio Player PRO (UAPP): 24- and 32-bit playback, ubiquitous USB audio support for Android

[Trunkmonkey44]

OK. I'll admit it; I'm thick.

But for the life of me, I can't find the in-app purchase for MQA support. If I tap "MQA Playback" in the slide-out menu, I just get a popup dialog telling me that, "[t]his app includes MQA technology,...".

Similarly, if I go to "Settings > MQA", I just get settings for MQA ("Show MQA playback information", "Deep scan", "Scan URL without file extension".

I've looked all over the app for the option to purchase the MQA add-on but for the life of me I can't find it.

Can someone stop laughing at how stupid I am long enough to point me in the right direction?

Doesn't this mean you have already purchased it? It is what I see after I bought it. Maybe purchased on your account previously for another device?

As a side note, after a new installation of UAPP on a new device, I went into the settings for MQA and it looked like I could buy it. I exited and restarted since I already own the add-on, and the next time I looked at the MQA settings I saw what you are seeing.

Another possibility is that your DAP/DAC is a full MQA decoder in which case you do not need the in-app purchase. What DAP/DAC are you using?

I thought about that. I don't remember purchasing the MQA support. I looked in my Google Play purchase history and can find the original transaction for $10 to purchase UAPP itself but I don't see a purchase of the MQA add-on. But the app does, indeed, seem to be behaving as if I own the add-on already based on your description above.

That could be it!

I've got UAPP installed on two different devices: a Hiby R6 (this is where I see the behaviour I listed above) and a Google Pixel 3a XL. I'm planning to use the Pixel 3a with a Hiby FC3 MQA dongle (which is due to arrive in the post any day now). Wanted to purchase the MQA support for the latter device. When I tap the "MQA playback" option on the Pixel, I get a different popup telling me that "MQA PLayback requires bit-perfect audio..." which, of course, I don't have on the Pixel until the FC3 arrives.

Guess I'll just cool my jets until the FC3 arrives and try again.

If the DAC is a full MQA decoder (as opposed to a renderer) UAPP sends the unaltered stream to the DAC without the 1st unfold. The DAC then does all of the unfolding. If the DAC is non-MQA or a MQA renderer, UAPP does the 1st unfold and then sends it to the DAC. Then, if the DAC is a MQA renderer, the final unfolds are done on the DAC.

This is what I expect too. They, the producers, say it's a full mqa decoder. Yet there is no unfold.

Per the MQA spec, DACs are only supposed to show the bitrate of the source (master) that was used. There are quite a few 16 bit 44.1 kHz tracks on Tidal that are MQA encoded. I suppose they are supposed to be better than normal FLAC.

Try this track:

You might be right, yet it's confusing, they show this on their website:

 

[LightBlue77]

Even more confusing, original 352, but uapp shows 44.1 khz on usb dac.

 

[rlw6534]

Even more confusing, original 352, but uapp shows 44.1 khz on usb dac.

Nope, that's totally correct. That track is a 352.8 kHz master that was encoded to 44.1 MQA. UAPP simply sends the unaltered 44.1 kHz stream to the USB DAC (if it is a full MQA decoder). The DAC does both the 1st (core) unfold and the final unfold(s).

MQA can be very confusing...

 

[LightBlue77]

This what metadata shows too so I guess it does what it should. Still confusing though

Hiby R8 being MQA decoder shows in UAPP full unfold bitrate value in “direct” field.

Have you attempted to play an MQA file?
I think that's when the purchase option appears.

I'm very impressed with UAPP after more than 1 week of usage.
May I know what is UAPP role in MQA via Tidal?
Since I can hear an improvement in sound quality between Hifi and Master album/tracks, I'm interested to know how it works compare to DAP like R8 etc which able to 16x unfold....

check this thread or mqa or uapp websites for answers, they have been repeated over and over here

Thanks for the tip. Got my answer in the menu bar.
Menu ->MQA playback ->"on the extream website"

I have played an MQA file (on my Hiby R6) and it plays. Once my FC3 arrives, I'll try it on the Pixel (which definitely doesn't have MQA support natively) to see what happens.
