Third test of the day (After #09 on Compaq, and #07 on Terratec). Performed 48 hours after the Compaq test on the same sample (I forget all results). --------------------------------------- 1L File: Sample08\macabre_ogg.wav 1L Rating: 3.1 1L Comment: Noise. Annoying on cymbals, covered by hiss, and losing their own dynamics and details. Beginning is rough ; some wind instruments are dusty... Not too annoying, but it gives to me a dirty impression. Vorbis I suppose --------------------------------------- 2L File: Sample08\macabre_anch.wav 2L Rating: 1.0 2L Comment: Heavy distortions. Some ringing. Trembling winds. --------------------------------------- 3L File: Sample08\macabre_lame.wav 3L Rating: 1.8 3L Comment: Winds and strings are too much distorted. Cymbals are well encoded, compared to some files. But winds and strings are dominant -> low notation --------------------------------------- 4R File: Sample08\macabre_mpc.wav 4R Rating: 2.7 4R Comment: Less energy on cymbals, which are distorted -> orchestra is less powerful. Metallic coloration. Some undulating sound (strings and wind). Some washing-machine sound (12-14), which reminds me mpc noise. --------------------------------------- 5L File: Sample08\macabre_wma.wav 5L Rating: 4.4 5L Comment: Sound is a bit synthetic. Some winds are not cristal-clean, with some dust (sec. 4.0 for exemple). Nevertheless, sound is close to perfection : cymbals are OK, and instruments are well-reproduced, without any annoying artifact or unatural note. Bravo ! --------------------------------------- 6R File: Sample08\macabre_mp4.wav 6R Rating: 3.3 6R Comment: Distortions. Low energy on cymbals, distorted. Few artifacts on others instrument. Nice, but not perfect. Same washing-machine feeling than #4, but less-pronounced --------------------------------------- ABX Results: Original vs Sample08\macabre_ogg.wav 8 out of 8, pval = 0.004 Original vs Sample08\macabre_anch.wav 8 out of 8, pval = 0.004 Original vs Sample08\macabre_lame.wav 8 out of 8, pval = 0.004 Original vs Sample08\macabre_mpc.wav 9 out of 10, pval = 0.011 Original vs Sample08\macabre_wma.wav 8 out of 8, pval = 0.004 Original vs Sample08\macabre_mp4.wav 8 out of 8, pval = 0.004
