Are my ears broken? Reply #50 – 2010-03-14 21:23:59 Quote from: solive on 2010-03-14 20:40:11So what criteria do you use in defining the performance of a standard playback system for testing codecs?That's a good question, one for which I don't have an answer. I believe people should conduct DBTs on their own equipment set up in the most typical fashion for them. While I think public listening tests are useful and can provide a general baseline for people, I put more emphasis on personal listening tests. In the case of public listening tests, I think there should be some type of control over playback hardware and environments, but I don't think it's a make or break situation. If people really want to know what codec and settings to use, they should perform their own personal tests rather than rely on results from public tests.My initial point to which you objected was to address the audiophile myth that audiophile grade components are required to most easily distinguish lossless from lossy. The people who perpetuate this myth are usually the very same people who think they can tell night and day differences between lossy and lossless but have never conducted a well-controlled double blind test.
