Re: Opus 1.3-beta is here Reply #125 – 2018-02-03 15:25:07 You have done a lot of interesting tests. Thank you.The thing is that developers are interested in comparison between oldtf vs newtf2.It’s already know that newtf2 or any other lossy files won’t be transparent at those rates but still can have high quality.ABC/HR should be used in order to compare “old tf” vs “newtf2”. Not ABX comparator.Here is some info on ABC/HR https://web.archive.org/web/20110611013208/http://ff123.net/64test/practice.htmlAnd other thing. 5/5 (probability of guessing, p=3%) is already enough for ABX log in testing lossy codecs. It’s even more true for ABC/HR. Nobody pretends to think that you fake a results or try multiple times in order to get “valid” results.You can probably download some ABC/HR app for your Linux distro. Here is one http://listening-tests.hydrogenaud.io/igorc/aac-96-a/ABC-HR_bin.zip Some documentation http://listening-tests.hydrogenaud.io/igorc/aac-96-a/readme.txt(Well, Java can give some headache)Testing Opus newtf2 vs oldtf is hard because differences between them are rather small at least in this moment.
