Level Control
Your next job will be to identify the noise level of the audio. With the appropriate range
selected, pull all six Band Gain controls and the Level control down fully or use the
DNSQuickStart preset to do so. Now increase the Level slowly. At first, you will hear very little
happen but, at some point determined by the noise content of the recording, you will hear the
noise disappear. You should attempt to determine the point at which this occurs.
When the Band Gain controls are fully down, maximum processing occurs for
any given Level setting, thus making identification of the noise easier
Band Gain Controls
Once you have chosen the range and determined the Level, you control the action of the
DNS2000’s filter bank using the Band Gain controls.
The six faders represent six frequency bands (each containing multiple filters) distributed from
lower frequencies (left) to higher frequencies (right) across the selected range.
You will use the Band Gain controls to control the amount of noise attenuation performed in
each band, adjusting them to suppress as much noise as possible without introducing unwanted
artefacts into the desired signal.
Noise suppression occurs in a given band when the fader is below 0dB. However, there are
occasions when you might wish to boost the signal in a given band, and you can do this by
moving the appropriate fader above 0dB.
Creating generic settings files
If you save a Settings file in the Pro Tools Librarian menu window with ‘None’ selected as the
DNS processor, you can reload this file when connected to a given DNS and the control
parameters will be retrieved without changing the selection. The DNSQuickStart file is an
example of such a file, and can be used to initialise the control settings of any DNS.
If a DNS is specified when you save a Settings file, your system will attempt to reconnect to it
when you reload that file.
Tutorials
The following three tutorials illustrate ways to use the DNS2000. They may not be the ways that
you choose to operate it for all jobs, but they will get you started.
