Apple Music Announces Spatial Audio and Lossless Audio

I highly suggest that people check out/try out "ABX comparator" plugin for Foobar2000 player. You give it two files (say a 128kbps mp3 version and a lossless flac verison) and it runs you through a double blind test of the two versions, quizzing you along the way. It's not just "listen to A" "listen to B", it gives you lots of options to listen to them and compare them in different ways, including obfuscating what track is A and what track is B.

If you think you can really hear fine differences in audio, it can be very eye opening (ear opening?).

+1 I have nothing against NPR but that has like 5 samples and absolutely nothing about methodology.

As far as I know, the goto test is: http://abx.digitalfeed.net/

They have a few other tests heres: http://abx.digitalfeed.net/list.html

I wish people would stop posting this useless test.

It compares FLAC with 320 Kbps AAC which no streaming service uses (Apple uses 256 Kbps) and is a very high bit rate.

And its choice of indie tracks isn't suited for demonstrating codec artefacts. At least have classical, EDM etc as well.

There's a great tool for creating online ABX tests: https://abxtests.com/

The guy who made it, jaakkopasanen, is also the author of other great audio tools - AutoEQ and Impulcifer.
