It is obvious that YT starting to use strange and false compression
scheme (and may be EQ as well) sometime in June 2008. Because
everything I uploaded up till that point sounded fine compared to
original sound I uploaded but not any more. The main problem is too
much compression and peak level is set to exceed max value of 0db in

their current settings probably by an error by inexperienced engineer
in audio field, in turn it results clipping sound in loud passages and
produces unacceptable breathing sound/noise in quiet passages which I
checked the wave forms on encoded audio track by YT. In other words,
loudest passage of the given track is encoded above 0db by some reason
and all those parts would sound distorted being clipped. Peak of
clipped wave form resembles to Trapezoid since any signal exceeded 0db
would be pushed back down to 0db instead of smooth mountain top shape/
curve how natural dynamics should be reproduced. To work around with
this problem after several experiments, 1) The peak of uploading audio
track should be kept under -3db (or normalize entire track to -3db or
even less) and this seems to help avoiding loud passages being clipped
Review<Web>: Songza, the Google for Youtube Music, make the mark ::
Nov 14, 2007 I always release the article after proof-read it to my best of ability first, get played and i can hear them well. there is nothing wrong with my sound device. Streaming audio is not using port8080 (default for http protocol). jini, I doubt that Songza is working at all behind firewall.

by YT compression. 2) However this would not help quiet passages to
remain in original level, they will be boosted up nearly 12db or even
more along with hiss and noise thus resulting typical audible
breathing effect. If you have cooledit pro or similar professional
audio tools, you can mix inaudible signal (20,000hz since wave) over
those quiet passages to boost overall level to around -4 to -6db. For
example, if your quiet passage is -16db, you can overlap mixing -6db
20,000hz sine wave will results around -4db signal power, thus YT
compression will not boost this passageâ ™s signal that much and it
remains in original volume or reverb decay etc. Itâ ™s a bit tricky, but
it works both in theory and practice. Or, to make it simpler,
normalize original track to -6db and mix -8db 20,000hz since wave over
entire track and this will result around max peak around -3db and
quiet passages will be raised dramatically without making any audible
difference, but it will not be boosted by YT compressor during
encoding, though I have not tested this method yet. 3) As for EQ, it
requires a bit more extensive test to see how and how much EQ being
applied by YT encoder, however I have some idea how to test this when
I find time to do so, but it would be much faster if YT audio
department fixes all those glitches on their end soon, basically just
use whatever they were doing in the past few years and that was
absolutely fine considering bitrate limit.
