Thank you for your reply. The noise appears only in the part of high
note of piano just like pre-echo in mp3 files. However, I think it must
be my system since I asked several friends to test the same files and
we didn't find any noise on their systems. Again, I think that Vorbis
should not have the same problem as mp3 has as it is not limited in this
way. Honestly, except this, I hadn't found any remarkable problem after
Beta 2 at 350 bitrates. Even an ignorant guy like me can see it's getting
much better.
I'll keep using Vorbis and if I find something, I follow your advice.
However, in this case, what should be checked is my system, I think.
Again, thank you for your advice.
Good luck on your development, team.
