points to a new Operational Practice 48 which is supposed to control the loudness of commercials. You know, the compression etc they use to make to TVCS stick out from normal programming. But is this OP 48 useful? ... or is it a load of baloney?
"Producers will be required to certify that their commercials comply with this
OP as a condition of acceptance for broadcast. This will require a
declaration of compliance when the commercial is submitted to the
broadcaster."
Yet the OP does not set any new standard whatsoever as far as I can see.
Section 4 merely repeats the industry standard lineup signal requirement that has existed for years
Section 5 deals with compression, limiting and equalization - but talks about "appropriate use" of that technology so as not to produce "excessively noisy or strident" material.
There is, as far as I can see, no measure or specification of loudness or perceived loudness whatsoever, yet the post houses (such as FSM whose newsletter alerted me to this) are now announcing they will include "compliance to the OP48" on their ident boards(!) even though there is apparently no way of measuring compliance! What???
Can a soundy explain this to me? What have I missed?
