2)       Calibration:

·         Use sticky pad for notes

a.       1st sticky: RCN, # of .WAVs generated, Time for Pass

b.       2nd sticky: Gain Changes – Follow spec for:

o        Noise Floor

o        RMS Audio Level: (>12dBFS or <16dBFS)

- (if Level reads -7dB, lower by -4dB – mark on sticky)

o        ?

(usually done if 1st line <15s, but if >15s paste in 1st line)

*Whenever you have another .WAV file in the same SMIL file, it’s not the next phrase.

 

.XML Notes:

 

C:\DTBEdit\DTB\?

Index tones come before each chapter
