Is your audio system really ready for lossless sound?
Here you will find a set of ABX tests allowing you to compare lossless and lossy compression in a variety of formats and bitrates. This site is still in its infancy, and the number of tests available will probably grow over time.
Currently we offer the following tests:
The statistically valid Tidal test remake
The Spotify HQ test
(oggenc -q 9)
The Spotify standard test
(oggenc -q 5)
The iTunes test
(iTunes AAC 256kbps encoding)
The Lame MP3 tests (available in 96-320kbps)
(varies)
The FAAC 320kbps test
(faac -b 320)
The OPUS 160kbps test
(opusenc --bitrate 160)
The text on each is mostly identical because they are a rapid expansion from the original Tidal-test-remake page created 25th Nov 2014. That will change with time.
