Remove DC Offset dialog
The Process > Remove DC Offset command opens the Remove DC Options dialog, which allows
you to remove audio artifacts cause by electrical mismatches between recording hardware and input
instruments or devices. This dialog has the following fields:
• DC Offset Threshold (dB). You can set a minimum dB threshold. If the analyzed DC offset is
below this value, no removal takes place.
• Analyze Left Channel (dB) and Right Channel (dB). This field displays the DC offset
separately for the left and right channels. Press the Audition button to update the display.
• Compute DC Offset from first 5 seconds only. To speed processing, select the Compute DC
offset from first 5 seconds only check box. Only the first five seconds of a sound file will be
analyzed when measuring the DC offset. The only time that five seconds is not sufficient is if a
long fade-in or mute has been applied at the beginning of the file.
Remove Silence dialog
When you use the Process > Audio > Remove Silence command, or click the Gate Settings
button in the Freeze Options dialog, the Remove Silence dialog box appears. This command
creates absolute silence during silent passages, eliminating extraneous noise.
The Remove Silence dialog box has the following fields:
Preset field (only appears with Process Audio command)
Use this field to choose and enter presets. Click the Save button to save any group of new settings
after you enter a name in the Preset field. Click the Delete button to delete any selected group from
the Preset field.
Open Level (db)
The value in this field is how loud the sound must get (the loudness threshold) before SONAR stops
silencing the sound. The gate “officially” opens when loudness rises above this level, although it can
open earlier because of the Attack Time (see below).
Close Level (db)
The value in this field is how soft the sound must get (the softness threshold) before SONAR starts
silencing the sound. The gate "officially" closes when loudness falls below this level, although it can
stay open later because of the Release Time (see below).
