ITU Weighting Curves
 

Does anyone here have copies of the
ITU-R 468 or ITU-R ARM ??

They are similar but ITU-R ARM is a later
Dolby Labs proposal which moves
the whole curve 1kHz to the right.

TIA

Thanks Don. I found that a while ago. I am interested
to see the printed docs, and history of the two curves.

Well, you can get a copy from ITU for 20 Swiss Francs. By now they
should have followed ETSI in making standards free, but it is
Switzerland.

Excellent. I received that info this morning from a German colleague
who can obtain them for SFr8. I shall send a carrier pigeon.

The history of this whole noise weighting scenario is an interesting one.

You aren't going to see that unless you get hold of the whole series,
revision by revision.

I'm ROTFLMAO over this self-proclaimed high roller named Iain who is now
quibbling over the princly sum of Sfr20.
