Setting up PPM meter
 
Hi there i have an edius 2.5 with storm 2 editing set up. I have recently added the beguelle ppm meter to my setup, which i have seen work excelently at a tv company.
www.belleguelle.net free 1 month trial if anyone wants it.

There is some advice given for setting up, and what is needed is a test tone of a known recomended ppm so i can calibrate it. I cant find any option in edius to do this, any suggestions?

I can create tones in Sound Forge, what frequency, level (relative to 0dBFS) and duration do you need. Any specific bit depth and sample rate? I'm guessing 16/48K to match DV.

Might be big files so I could email them to you.

48k rings a bell, just lookin through settings, cant find. Am using pal, is that what austrailia uses too?

Cant remember what the norm is, think it was 6 ppm the test tone was set at at company i used to work for.

Thankyou. My email adress is ihadaeureka@hotmail.com

PPMeter, available from Raw Material Software, comes with a built in calibration test tone. They have a free trial available. You might want to check it out.

The bitrate/sample rate don't matter for purposes of calibration, it's level and frequency.
There is a package of free tones available.
You do have to register to download them.

Looking up my old BBC notes - 1k Hz tone at 0.775 volts into 600 ohms is the reference level for mono - lined up on "4" on the PPM.
