Before anything I have to thank Sebastian again for having conducted this nice MP3 Listening Test @ 128 kbps!
I think I was too hard rating the samples but my results are very similar to the overall results:
My Average Test Results
iTunes 8.0.1 2,45 4,26
Lame 3.98.2 2,94 4,51
l3enc 0.99a 1,00 1,56
Fraunhofer 2,84 4,44
Lame 3.97 2,77 4,28
Helix v5.1 3,20 4,59
"Test Results" are the results of all participants. "My Average" is a simple linear average of the results as I don't remember how to do other type of analysis (too long ago ). Taking out the highest and lowest result of all encoders produces a similar result as presented above. If anyone can tell me which formula to use in MS Excel to get error margin please do.
I'm really surprised an encoder that hasn't been tuned since 2005 gets these good results. I have more samples Helix doing better than Lame 3.98.2 than the other way around allthough differences are small. When doing the Test I noticed clearly 2 encoders were better than the rest and I thought they were the Lame ones
