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.
