Remove DC Offset dialog

The Process > Apply Effect > Remove DC Offset command opens the Remove DC Options dialog box, which allows you to remove audio artifacts cause by electrical mismatches between recording hardware and input instruments or devices. This dialog box 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.
