Be more specific - not sure how to understand your question (i assume this is question).

[roma_turok]

I need to make video file with specification for AUDIO must 6.25 ppm peak
I think that mean sound need normalize to specific level

[aedipuss]

UK broadcast spec used to be peaks no higher than -10db - average should be between -11db to -18db

ppm is a bbc audio peak power meter device.

Thank you.

Nope, once again - this is confusing as ppm is not equal to PPM, dB are not dBFS etc.

So once again you need to be very precise...

dBFS exist only in digital world and this must be converted to dBu (and this is related to hardware used in studio). Adobe use dBFS not dB or dBu.

pandy is correct. dB is a RATIO, and a ratio is only valid & useful when you have a REFERENCE to use a ratio as a comparison.

There are a number of references used with dB: FS (digital "full signal"), u, m, VU, SPL, etc. depending upon the circumstances.

PPM isn't a "ratio" per se, but it does compare your signal against some reference (which varies depending upon nationality & circumstances). PPM is primarily an ANALOG metering tool and it isn't normally an INSTANTANEOUS PEAK reading, so a bit of math would be necessary to convert to or from the common, digital metering of dBFS (which works with instantaneous peaks).

It would probably be a lot easier if you backed up and just told us WHO you are sending this to and what they said they needed from you (VERBATIM). Problems often arise when sending a tape/file to a production or broadcasting agency where the "published" spec requirements were created by a non-engineer (or a very sloppy or not-fully-knowledgeable engineer), typically a marketing or admin liaison to the engineers.
Often this confusion can be resolved by directly contacting the CTO (chief technical officer), who should be able to calculate & translate their requirements into terms you can work with.
