ABC/HR Version 0.9b, 30 August 2002 Testname: 1R = D:\Temp\HQ test\[MP3 3.97a3 -V 2] Platée I,6.wav 2L = D:\Temp\HQ test\[aoTuV MGX -q 5,50] Platée I,6.wav 3L = D:\Temp\HQ test\[aoTuV MGX -q 6,00] Platée I,6.wav 4R = D:\Temp\HQ test\[aoTuV MGX -q 5,99] Platée I,6.wav 5R = D:\Temp\HQ test\[MPC SV7 1.14 -q 5] Platée I,6.wav 6R = D:\Temp\HQ test\[MP3 3.97a3 -V 3] Platée I,6.wav --------------------------------------- General Comments: Purpose of this test: measuring the quality of the harpsichord (and other instruments, but harpsichord is easier to isolate from background), which is not the main instrument of this peace: the orchestra covered him. Distortions, smearing, blurring are expected. --------------------------------------- 1R File: D:\Temp\HQ test\[MP3 3.97a3 -V 2] Platée I,6.wav 1R Rating: 3.0 1R Comment: the harpsichord sounds wrong, distorted. Reminds me LAME encoder (or nspsytune psycho-model?) with this instrument (solo recordings). But the problem is less pronouced: just a reminiscence. The instrument is neverthless blurred, unsharp --------------------------------------- 2L File: D:\Temp\HQ test\[aoTuV MGX -q 5,50] Platée I,6.wav 2L Rating: 2.2 2L Comment: seriously distorted, maybe less than previous file. But there's now a second and unexpected problem, much disturbing: fat image of orchestra (vorbis I suppose). --------------------------------------- 3L File: D:\Temp\HQ test\[aoTuV MGX -q 6,00] Platée I,6.wav 3L Rating: 3.0 3L Comment: Distorted, but contrary to the previous file, I can't blame this file from any "fat" or "coarse" texture. --------------------------------------- 4R File: D:\Temp\HQ test\[aoTuV MGX -q 5,99] Platée I,6.wav 4R Rating: 2.4 4R Comment: sounds like the second file (2L): coarse orchestra retains my attention. Problem seems less pronounced. Harpsichord is still distorted and messy. --------------------------------------- 5R File: D:\Temp\HQ test\[MPC SV7 1.14 -q 5] Platée I,6.wav 5R Rating: 3.8 5R Comment: Messy sound. The harpsichord is unprecise, uncoherent, and distorted. Less annoying than other files (problem is subtle). --------------------------------------- 6R File: D:\Temp\HQ test\[MP3 3.97a3 -V 3] Platée I,6.wav 6R Rating: 1.8 6R Comment: More distortions here. Really annoying --------------------------------------- ABX Results: Original vs D:\Temp\HQ test\[MP3 3.97a3 -V 2] Platée I,6.wav 8 out of 10, pval = 0.055 Original vs D:\Temp\HQ test\[aoTuV MGX -q 5,50] Platée I,6.wav 5 out of 5, pval = 0.031 Original vs D:\Temp\HQ test\[aoTuV MGX -q 6,00] Platée I,6.wav 9 out of 12, pval = 0.073 Original vs D:\Temp\HQ test\[aoTuV MGX -q 5,99] Platée I,6.wav 6 out of 6, pval = 0.016 Original vs D:\Temp\HQ test\[MPC SV7 1.14 -q 5] Platée I,6.wav 6 out of 6, pval = 0.016 Original vs D:\Temp\HQ test\[MP3 3.97a3 -V 3] Platée I,6.wav 6 out of 6, pval = 0.016 D:\Temp\HQ test\[MP3 3.97a3 -V 2] Platée I,6.wav vs D:\Temp\HQ test\[aoTuV MGX -q 6,00] Platée I,6.wav 15 out of 30, pval = 0.572 D:\Temp\HQ test\[aoTuV MGX -q 5,50] Platée I,6.wav vs D:\Temp\HQ test\[aoTuV MGX -q 5,99] Platée I,6.wav 9 out of 12, pval = 0.073
