I have recently been involved in a string quartet
recording. It has been a challenging project.
Everyone was delighted with the performance
and the sound on the production master which
was sent to a CD plant in the UK for 1:1 duplication.

When a run of 500 copies is required, a glass
master normally needs to be made for replication.
The client gave permission for this to be done by
the CD plant, on the understanding that no audible
changes were to be made, as the production master
was exactly what was requiired.

I asked to be informed when the finished discs had
been received. Yesterday, I received a phone call
from a very disappointed cellist.

She said, "Every nuance of our performance has
been destroyed. We sound like the musical equivalent
of ballet dancers in jack boots!"

This morning, I had the chance to compare a
portion of the envelope from our production
master (the left-hand side of the pic) with the finished
CD (right had side)

Take a look:
It's not pretty!

Pretty dreadful! If they'd only normalised it to -1dBFS or even, at a
push, 0dBFS at least it would have preserved the dynamic range, but what
they did was
nothing but vandalism.

My guess would be compression maybe 6:1 then considerable
make up gain and brickwall limiter at Inf:1 at OdB FS for a hard
ceiling.

Many pop CDs are mastered like that.

Looks like LP on the left CD on the right! :-)

Hope all is well with you Serge. I was talking to an associate of yours some
time back (Mike Bray) - he sent his regards.
