I want to ask everyone. Before the test finish, which codec will win? Of course you may have to take a guess/bet or based on your experience/personal preference.
A (IMHO) more important question: Igor, are all session results excluded for which some hidden reference is graded with less than 5.0? Maybe you should mention the post-screening procedure so that listeners behave carefully enough.
If at least one of the following errors takes place then the result will be INVALID.1. graded the reference lower than 5.02. didn't grade the low anchor.If one listener will submit INVALID result then he will be informed and will have one more and unique posibility to submit result for one particular sample.Now if the listener will submit 3 or more invalid results then only ABX results will be accepted from him/her or directly rejected in abussive cases.
And about the resampling: Except for CELT, was the input or the output of the codecs resampled to 48 kHz?Chris
Tried to abchr.jar (+jdom.jar, looks-1.3.1.jar) from here http://www.hydrogenaudio.org/forums/index....st&p=701994?The same result. Strange...
The Java 5 build should also run fine on Java 6 machines. In both cases just double-click the jar to start.
Participants who don't want to worry too much about the grading rulescan simply ignore them. Listeners should do their best to rank the samples and be careful to identify the hidden references. Listeners should ABX teststhey are at all unsure.1) If the low anchor is not graded, or if any hidden reference is graded below 4.5-5(*1a) (see App.) the result is INVALID. *1a It will be discussed with people who have experience of conducting public tests when final results will be ready.2) For each sample with a ranked reference or an ungraded low anchor thelistener will have a single chance to submit a replacement test run forthat sample. The replacement test must cover all codecs, not just thecodecs with the ranked reference. (This also covers cases where thereference is ranked but still at or above 4.5)3) If a listener submits more than 2/15 (4 for 30 samples submitted) INVALIDresults then only ABX results will be accepted, or the listener will be excludedcompletely in cases of apparently abusive behavior.App. These rules aren't extremely strict in order to allow for simple humanerror while still excluding careless participants.A stricter procedure to exclude all ranked references risks a systemicbias against any codec which are very good on a few samples and thussubject to more reference confusion by causing those samples to be excludedand weighing the test towards other samples.
I just noticed that this test is not in the forum news.
Thank you, Sebastian. There are two versions of ABC-HR for Java 5 and 6. http://www.hydrogenaudio.org/forums/index....st&p=683924Fool_on_the_hill, you can try itCode: [Select]The Java 5 build should also run fine on Java 6 machines. In both cases just double-click the jar to start.
still the same error
Two in particular appear essentially transparent to my ear across the entire set of samples. I can only hope that those two are consistent and it's not a cycling of which is best in each case
