ABC/HR Version 0.9b, 30 August 2002 Testname: TheSource Listening Test 1R = Sample11\TheSource_mpc.wav 2R = Sample11\TheSource_ogg.wav 3R = Sample11\TheSource_lame.wav 4R = Sample11\TheSource_wma.wav 5L = Sample11\TheSource_anch.wav 6L = Sample11\TheSource_mp4.wav --------------------------------------- General Comments: #4 and #6 sound fine as far as my ears are concerned. The easiest section to ABX on the others is from about 11.7 to 13.5 seconds. --------------------------------------- 1R File: Sample11\TheSource_mpc.wav 1R Rating: 3.7 1R Comment: Some loss of stereo separation. The hi-hats in particular have moved from slightly left to almost center. Easy to hear once I was aware of it. When she takes a breath after singing "hands up in the air", I think it sounds slightly different, but I can't really say how. I don't think the problems with the snaps are as noticeable as with #2 and #3. --------------------------------------- 2R File: Sample11\TheSource_ogg.wav 2R Rating: 4.5 2R Comment: Hi-hats are a tad smeared, as are the snaps. --------------------------------------- 3R File: Sample11\TheSource_lame.wav 3R Rating: 4.0 3R Comment: Between #1 and #2. Stereo separation of hi-hats is better than #1 (but still moved a bit towards center), snaps are slightly worse than #2. --------------------------------------- 5L File: Sample11\TheSource_anch.wav 5L Rating: 1.0 5L Comment: Must be blade... Noisier overall, snaps sound really bad. --------------------------------------- ABX Results: Original vs Sample11\TheSource_mpc.wav 10 out of 11, pval = 0.006 Original vs Sample11\TheSource_ogg.wav 18 out of 26, pval = 0.038 Original vs Sample11\TheSource_lame.wav 10 out of 10, pval < 0.001 Original vs Sample11\TheSource_wma.wav 2 out of 7, pval = 0.938 Original vs Sample11\TheSource_anch.wav 10 out of 10, pval < 0.001 Original vs Sample11\TheSource_mp4.wav 6 out of 12, pval = 0.613
