Preparing for Audio Output
You can use the Audio tool to generate and customize a calibration tone and to monitor global
output levels. Use the Audio Project settings to adjust the global output levels and specify other
output settings. The following procedures provide information about preparing for audio output.
For information on audio mix procedures such as adjusting volume and pan for selected tracks or
audio mixdown, see “Working with Audio” on page 712.
Setting the Calibration Tone
The Audio tool provides an internal calibration tone you can customize and play as a reference
signal on a digital cut. You can use the recorded reference signal for calibrating the digital cut
audio at another site.
The default tone playback is –20 dB (digital scale) or –14 dB (software-only systems) with a
1000-Hz signal. In some cases, you might need to customize the signal. For example, a common
reference signal convention for audio work involves recording 30-second segments of 1-kHz,
10-kHz, and 100-Hz tone back-to-back.
For information on creating tone media, see “Creating Tone Media” on page 176.

1. Select Tools > Audio Tool.
The Audio tool opens.
2. Click the PH (Peak Hold) menu, and select Set Calibration Tone.
