Pro Tools Metering

Here are some pages I found on metering within Pro Tools:

Pro Tools uses the dBfs scale on its meters, which are no use to us when it comes to mastering. We need to obtain a PPM meter plugin (one that complies with BBC standards).

I have come accross some PPM software: http://www.darkwooddesigns.co.uk/pc2/meters.html, the main problem with this is it is not a plugin and seems to measure input signals and also 'what you hear' computer output signals. With some clever routing we could possibly use this software, though I think we should try and locate something more suitable.

I have come across a page from the BBC that offers PPM meter download: http://www.bbc.co.uk/opensource/projects/baptools/

There are also other plugins recommended some of which come with a free trial, which would be perfect for us:
