Title: Playing 24bit files with smartphone thru stereo system
Post by: firemt66 on December 31, 2019, 11:44:06 AM
Hello,when i play 24bit files with my samsung 9+ thru a 10year old av reciever,  does it down sample to 16bit as it plays or am i playing 24bit and if thats the case is that better sound than the 16bit..this is all with the latest ZEP boxsets with the download hi resolution cards...

Here are the Android media format details: https://developer.android.com/guide/topics/media/media-formats

If they are FLAC, then they should be playing in 24 bit.

After doing my own ABX testing, I know that I don't possess the golden ears required to enjoy 24 bit. Doing your own testing on your system is the only way for you to answer the 'better sound' question.

Might be constrained by the interface between phone & receiver.
IP or Bluetooth?

get a chromecast audio it can do lossless

 Cable from the reciever to my phone..we did a comparison with what is and what should never be last night..lp sounded better than the 24 bit file

A lot of variables here.  Volume level matching is one of them.  Invariably one source will be louder than the other which is the most common reason people hear "better".  There's also mastering involved different engineers and different mastering sessions can be quite different, it's why vinyl aficionados chase specific pressings. Another is the amplifier section of your phone vs the output stage of the record player.  You've got some tee-tiny components in your phone trying to generate a line level signal if you're connecting with a cable that is really designed to be headphone level output.  The electronics of the Vinyl pre are more designed for the job.  LP's have a lot of inherent EQ applied to them in both the encoding and decoding stages due the necessity of RIAA curves.  How it was mastered and how that reversal is being applied in your vinyl pre makes your comparison akin to comparing two sources with one having EQ applied, it won't be the same.  It can also be that the IMD of the record and more mid-range forward presentation of vinyl due to it's physical limitations is simply more pleasing to your ears.   

More modern receivers can replay 24 bit files natively and it would be a more fair comparison to compare using something along those lines.

Don't confuse digital and analog signal constraints
While digital has limits in the voltage of it's signaling, that is appropriately scaled to components (engineering) that are in use.
This is why digital is infinitely superior to analog formats.
Also the mechanical headaches, like motors, radiuses, viscous components, cantilevers, not to mention wear and tear, make analog systems less accurate reproducers of audio.
All of those things add unwanted artifacts and although digital has its own, they do not vary and may be much more effectively remediated.

That's a misquote, not sure whatcha did there...
My comment was regarding your bluetooth connection and the various types available.

I do not do or publish formal comparisons...
(and everyone on the board knows that I'm no fan of vinyl, but I do not judge....  Like what sounds good to your ears, not mine)

get a chromecast audio it can do lossless
to clarify, in ios mconnect app can play flac files from the phone and works with chromecast audio
google play app can prob play local lossless files as well (though everything in the cloud get suatomatically converted to 320CBR)

in android, i believe VLC can play straight to chromecast as well

chromecasting uses straight wi-fi and is not beholden to bluetooth codec limits
