Setting the Calibration Tone
The Audio tool provides an internal calibration tone that 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 –14 dB (digital scale) 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 100-Hz, 1-kHz, and 10-kHz tones back-to-back.
