creating accurate calibration tone for dubs
Hi. I was hoping to find out how to create an accurate calibration tone to run with my color bars for produced work. This was something I was never taught, and I can’t seem to find any information in the avid manual or online. I am normalizing my audio to -3 db. What should I set my tone at?

I park it at -14. As long as your laying down 0 vu, your cool.

Check where you’re delivering, let them know, either an ident on bars or on paper, they need to know the reference.

To actually make tone in your Avid, open your Audio Tool, click the PH and a menu will pop up. At the bottom of the menu is Create Tone Media. Click it, select the Dbs, frequency, length, number of tracks, media drive and bin. Hit OK and it’ll put that tone into your bin. Done!
Mike.

If you output to an VTR with analog audio, set your tone level in audio tool to -14. If you output to a digital VTR, set your tone level to -20. In both cases the audio in your program should be no higher than 10DB over reference (tone) level to be broadcast legal (unless you have specs that dictate otherwise).
You can create tone in audio tool to cut into your timeline (Create tone media) or use “play calibration tone” and record it directly to tape with bars from video output tool.
