There seem to be so many players for music. From laptop, from android, from apple.
a) Now from android --> if the player is using the native driver of android then definitely its not bit-perfect output. Hence usb player pro bypass the android driver and use their own. After some setting in the app, it outputs bit-perfect. That's why they say.
Other apps in android e.g. neutron, onkyo hf... Some of them upsample. and some don't.
How to know which player is doing bit-perfect output?
b) Same for laptop.
Jriver, foobar and others have the option to bypass windows driver and mixer and allow the option to choose WASAPI , ASIO and SCHIIT WASAPI aswell.
How to know which does bit-perfect output?
Seems mathematics and the underlying OS has given way to so much creativity and options that its becoming hard to find a way which does bit-perfect. :indifferent14:
