To perform removal, choose Effect > Normalize., with the option checked ' Remove any DC offset (center on 0 vertically)'. Removing DC offset Audacity's Normalize EffectĪudacity's DC removal method performs a calculation to make the average positive and negative sample values equal.

DC offset will become worse if the recording is amplified.

DC offset can cause audible clicks where audio sections are cut and pasted together, and can cause a click on playback at the start and end of the track, even without editing.

The distortion may become audible when effects that change the frequency content are applied, or when exporting the audio to a size-compressed format like MP3.

DC offset can cause inaudible low level distortion.

This problem can possibly extend to the mix as a whole, since a sound with DC offset and a sound without DC offset will have DC offset when mixed. This is because the offset reduces the headroom between the peak level of the audio and the maximum possible level without clipping.

A sound that has DC offset will not be at its loudest possible volume when amplified or normalized.

Yeah, yeah, you can disable all the extra toolbars you're not using in Audacity but I like things that are pretty out-the-box.You should check for and remove offset in any audio you are working with before editing it, even if the audio is not your own recording but an audio file you have obtained elsewhere. Personally I think the user-interface is waaay nicer than Audacity. What are the pros and cons of using it? How does it compare to Audacity? I'd be happy to link to your site, embed any recordings you've done with it, etc. I'd love to hear from any of you who have actually used it (or are currently using it). Stuff like noise reduction and, of course, other stuff none of us would ever use. But it still has support for a lot of the effects and plugins that Audacity supports.

There's no support for multiple tracks which means it's a bit easier to use than say Audacity or Ardour (or GarageBand, etc). During my research, I stumbled across something called ' ocenaudio'. I'm writing an article for my blog on all the free software downloads available for voice actors.
