■ THE AUDIO TOOL

So when setting reference level for output to an analog deck, set it at –14 dB.

For a digital source (such as DV cam, DVC Pro, DV decks and cameras, and any

FireWire destination), use –20 dB.

Setting Calibration Tone

Your Calibration Tone should be set to match your reference level, giving you true ref-

erence of the content. So analog destinations should be set to –14 dB. Digital destina-

tions for output should be set to –20 dB.

Creating Tone Media and Color Bars

You should always use bars and tone on your sequences. Let me repeat: You should

always use bars and tone on your sequences.

If you don’t, you might be setting yourself for a disastrous series of consequences

because your master might be copied in several different places by several different

dubbing facilities. Someone could end up complaining, and what do they have to com-

plain about? You, that’s who. When you put bars and tone on every output, it covers

your, er, umm ... rear end.

Think of it: Your audio goes to a dubbing house, in which the operator calibrates

it incorrectly. Then it goes to an ad agency, in which the agency’s dubbing facility cali-

brates it worse. That tape goes to the client, who listens to a tape with really bad audio.

Then someone at the agency gets blamed, the account is canceled, the agency sues the

post-production facility, and you end up going home for good.

On the other hand, there might be occasions when the client does not want

audio tone at the beginning of the tape. If this is true, put audio on the beginning of

your sequence, but create the output after the tone media in the sequence. That way,

you’ll have all your bases covered. Even if you output without bars and tone, make

sure that it is on your sequence in the edit, just to be safe.

Tone Media

To create tone media, click the menu box to the right of the audio meter (see Figure 4.18)

and choose Create Tone Media. A window appears (see Figure 4.19); let’s take a look

at what we can do to create tone.

Tone Media Level In dB This setting determines the level of tone. Before you switch it

to 0 dB, realize that we’re talking digital levels here, not analog. With Free DV and

Xpress Pro, the standard digital level is –20 dB. Unless you have some reason for

diverting from standard, keep it that way.

Tone Media Frequency In Hz Standard tone frequency is 1000 Hz. Again, this is stan-

dard and shouldn’t be changed unless the audio house recommends it.

Tone Media Length In Seconds Sixty (60) seconds is standard. If you need more, you

can always loop it. If you need less, then at least you’ll have plenty. Remember, we’re

just creating media here, not editing.
