Re: How to fix DC offset?

Many sound cards record with a slight DC offset, which means that direct current is introduced into the signal by the card, causing the center of the waveform to be off from the zero point in the waveform display. This is seen as the waveform being “shifted” above or below the center line in the Wave Display, and can cause a click or pop to be played at the beginning and the end of the file.

To compensate for DC Offset, you can choose the DC Bias Adjust setting in Effects > Amplitude > Amplify.
