Correcting the DC offset
In some audio clips, the zero point of the waveform may not be aligned at zero. (This is a limitation of the sound card.) The DC offset can result in distortion when you edit the recording. Sound Editor allows you to correct the DC offset.
To correct the DC offset for an audio clip:
1 In the Project View area, select the audio clip for which you want to correct the DC offset and choose Edit > Properties.
2 In the Clip Properties dialog box, select the Adjust DC Offset check box and click OK.
