This is the only one which sound much better on the first half than during the second one. - The first half is not transparent; in fact, it's a bit too distorted for my taste (very severe with harpsichord). But not bad for such bitrate. - The second half is clearly poorer. The quality quickly drops at ~10-11.00 and smearing becomes really high. I can't see any change in the signal which could explain this sudden drop. I wonder if it's not Nero Digital and its ABR mode, which uses more bits than average during the first seconds before normalizing it after few seconds. It may explain this weird phenomenon. If it's the case, it may be very worrying: I'm used to evaluate the quality of long samples on the first half (or even third) and to discard the remaining part from the evaluation. Then this encoder would be over-evaluated... ! I hope I'm wrong. For final rank: 3.5 for the first half; 1.8 for the second. --------------------------------------- 2R File: Sample10\LesJoursHeureux_5.wav 2R Rating: 4.4 2R Comment: Minor difference; slightly synthetic sound, but very good. --------------------------------------- 3L File: Sample10\LesJoursHeureux_6.wav 3L Rating: 2.5 3L Comment: slightly distorted; really smeared --------------------------------------- 4L File: Sample10\LesJoursHeureux_4.wav 4L Rating: 1.3 4L Comment: --------------------------------------- 5R File: Sample10\LesJoursHeureux_2.wav 5R Rating: 3.5 5R Comment: sounds often wrong with additional smearing. Not bad when compared to other challengers. --------------------------------------- 6R File: Sample10\LesJoursHeureux_1.wav 6R Rating: 3.7 6R Comment: sharp but sounds wrong, like a weird form of ringing (unusual with harpsichord). Typical distortion of iTunes 5/6 I'd say. --------------------------------------- ABX Results: Original vs Sample10\LesJoursHeureux_5.wav 8 out of 8, pval = 0.0030 ---- Detailed ABX results ---- Original vs Sample10\LesJoursHeureux_5.wav Playback Range: 12.801 to 15.393 10:10:07 AM p 1/1 pval = 0.5 10:10:10 AM p 2/2 pval = 0.25 10:10:15 AM p 3/3 pval = 0.125 10:10:18 AM p 4/4 pval = 0.062 10:10:29 AM p 5/5 pval = 0.031 10:10:36 AM p 6/6 pval = 0.015 10:10:41 AM p 7/7 pval = 0.0070 10:10:45 AM p 8/8 pval = 0.0030
