Frequency response while streaming stops at 15kHz- did I miss something in the fine print?


I am streaming with Qobuz.  It sounds great playing both CD quality and hi-rez music.  So what's the trouble?  While working to get the bass response in my room just right I found test tracks on Qobuz.  This was very handy as I played 30-60 Hz test tones over and over.  So when I was done with that I streamed a pink noise track and pulled up the FFT analyzer app on my iPhone.  Surprisingly, I see the trace drop straight down to 0 dB above 15 kHz.  I streamed some test tones and confirmed that above 15 kHz nothing is happening at the speakers.  In my old and decrepit state I can no longer hear above 15 kHz so I am relying on the app.  In a panic that something is wrong with my speakers I pull out my vinyl test record.  I have a nice, pretty flat frequency response from 20-20 kHz showing on the FFT app.  I put in a test CD and again show a good 20-20k.  Lastly, I ripped the test CD onto my server and again had a good 20-20k response.  So why did I not know about the limited bandwidth while streaming?  Is it just me?  It is an abrupt cutoff above 15 kHz while streaming.  What's going on?

Is it an issue? Show your last hearing test.
I’m my day hifi was defined as 50-15000.
Do you really need more than you can use.
Makes for good troll food though.
You get what you pay for with FM radio.
I sold my tuner years ago for what it was worth, next to nothing.

What kind of hardware and software are you using?

If you think that’s bad being band width limited, look at the dynamic range of it, as they use the later re-issues not the originals the way the band/s wanted it to be heard.
Then purchase CD’s that have not been compressed (usually 1st issue), search here for those.

Most later re-issues have been compressed.
Except some, but they command big prices $80 ebay used as this 2019 uncompressed Japanese one at the bottom.

Because nothing is compressed in life’s sounds, why do it to our music!!
Is a live artist you sit in front of compressed NO!
(my theory is for the companies to save space on streaming/downloads)

Also leaving it uncompressed gives the music a chance to breath, (you can’t have loud bits if there are no quiet bits), also gives the ears/brain a chance to breath as well, instead of everything being the same level and sounding confused.
