Audacity Forum

I think Audacity is fantastic. The sound quality is great, but there is one problem. At the beginning and end of each recording there is a "click" noise that I can't remove. This happens when played from Audacity and when playing from the exported track. It's no good trimming the track at the beginning or the end because the "click" then moves to the new beginning and end. Is there a way to stop this from happening?

I have a capture digital converter that does that. Try applying Effect > Normalize > Remove DC Level. Deselect everything else.

Sometimes broken or badly adjusted audio systems allow their operating battery voltages to leak into the sound. Battery or DC is not sound, so you can't hear that it's there, but it makes editing a nightmare because those clips will not mix or cut with anything else. Each Audacity version has tools designed to get rid of it.

The down side is you have to apply the tool to each and every capture until you sell the device -- assuming that's what the problem was.

Even downer is the problem that you can't take the DC out in post production. You have to remove it before you start editing, so your carefully edited clicky show is now at the top of page one.

That's great, Kos. It works a treat. Thanks for the advice.
