aoTuV vs. oggenc 1.0.1 filesize
Reply #18 – 2006-08-13 19:20:59
And about aotuv improvements. I'm sure aotuv's generated files have better quality, but they also have higher bitrates, so q1 vs. q1 are not comparable. It is like comparing oggenc 1.0.1 at q1 with oggenc 1.0.1 at q1.5. The particular song encodes below the nominal bitrate (80 kbps) with both implementations. Using headphones I can't hear any difference at all so my view is: I'm curious about oggenc 1.0.1 which you stick to. FYI here is my test result.[!--sizeo:3--][span style=\"font-size:12pt;line-height:100%\"][!--/sizeo--]aoTuV 4.51 vs oggenc 1.0.1 [/size] encoders aoTuV 4.51 -q 1.0 (bitrate 79kbps) aoTuV 4.51 -b 80 -m 80 (bitrate 84kbps) oggenc 1.0.1 -q 1.5 (bitrate 80kbps)sample macabre Result ABC/HR for Java, Version 0.52b, 14 8・2006 Testname: Tester: haregoo 1L = E:\Desktop\ogg\macabre_aoTuV_q1.wav 2R = E:\Desktop\ogg\macabre_aoTuV_-b80 -m80.wav 3L = E:\Desktop\ogg\macabre oggenc101_q1.5.wav Ratings on a scale from 1.0 to 5.0 --------------------------------------- General Comments: --------------------------------------- 1L File: E:\Desktop\ogg\macabre_aoTuV_q1.wav 1L Rating: 3.0 1L Comment: --------------------------------------- 2R File: E:\Desktop\ogg\macabre_aoTuV_-b80 -m80.wav 2R Rating: 3.0 2R Comment: --------------------------------------- 3L File: E:\Desktop\ogg\macabre oggenc101_q1.5.wav 3L Rating: 2.0 3L Comment: irritating additional noise --------------------------------------- ABX Results: E:\Desktop\ogg\macabre_aoTuV_q1.wav vs E:\Desktop\ogg\macabre oggenc101_q1.5.wav 8 out of 8, pval = 0.0030 ---- Detailed ABX results ---- E:\Desktop\ogg\macabre_aoTuV_q1.wav vs E:\Desktop\ogg\macabre oggenc101_q1.5.wav Playback Range: 10.406 to 14.866 1:43:07 AM p 1/1 pval = 0.5 1:43:10 AM p 2/2 pval = 0.25 1:43:13 AM p 3/3 pval = 0.125 1:43:15 AM p 4/4 pval = 0.062 1:43:19 AM p 5/5 pval = 0.031 1:43:22 AM p 6/6 pval = 0.015 1:43:27 AM p 7/7 pval = 0.0070 1:43:30 AM p 8/8 pval = 0.0030 Please note the following when you evaluate lossy encoding. Even if you could not find any differences, there can be differences. Evaluation with only 1 sample does not reflect real peformance on various music. This test means aoTuV 4.51 performs better on this sample for me. P.S. Use of Bitrate Management is NOT recommended in terms of quality.
