Revision as of 12:00, 24 January 2006
From time to time, HydrogenAudio members conducted listening tests, either public ones or private ones. These listening test should be valuable in gauging the performance of various digital audio techniques, e.g. compression, transcoding, etc., on a certain point in time.
It should be noted that these tests may become obsoleted by newer enhancements in the techniques. So please ensure that there's no newer tests before drawing conclusions.
This page contains links to Listening Tests carried out by various members of HydrogenAudio.
