ABC/HR Version 0.9b, 30 August 2002 Testname: thear1 Listening Test 1L = Sample10\thear1_wma.wav 2R = Sample10\thear1_anch.wav 3R = Sample10\thear1_mpc.wav 4R = Sample10\thear1_mp4.wav 5R = Sample10\thear1_ogg.wav 6L = Sample10\thear1_lame.wav --------------------------------------- General Comments: Is that a cowbell I hear? There was some clunking noise that kept thowing me off on several of the samples (it exists in the original, but sounds strange). --------------------------------------- 1L File: Sample10\thear1_wma.wav 1L Rating: 4.9 1L Comment: I'm fairly certain I'm able to discern a difference. I think the ABX result is iffy because it's barely perceptable and I'm up past my bedtime. --------------------------------------- 2R File: Sample10\thear1_anch.wav 2R Rating: 1.0 2R Comment: Nasty preecho on drum hit at the beginning. The rest of the clip sounds swirly, warbly and noisy with some weird high-frequency squeeking sounds. Blech. --------------------------------------- 4L File: Sample10\thear1.wav 4L Rating: 4.4 4L Comment: Same comment as #6, slightly less noiceable. --------------------------------------- 5R File: Sample10\thear1_ogg.wav 5R Rating: 2.0 5R Comment: Tinny sounding. Big high-frequency boost. Lots of irritating high-frequency noise. --------------------------------------- 6L File: Sample10\thear1_lame.wav 6L Rating: 4.0 6L Comment: Some high-frequency noise, but much. The most noticeable thing is a few hiccups in the guitar, esp. around 4 seconds or so. --------------------------------------- ABX Results: Original vs Sample10\thear1_wma.wav 28 out of 44, pval = 0.048 Original vs Sample10\thear1_anch.wav 10 out of 10, pval < 0.001 Original vs Sample10\thear1_mpc.wav 6 out of 13, pval = 0.709 Original vs Sample10\thear1_mp4.wav 10 out of 12, pval = 0.019 Original vs Sample10\thear1_ogg.wav 14 out of 16, pval = 0.002 Original vs Sample10\thear1_lame.wav 14 out of 19, pval = 0.032
