Audacity Forum

this is the first time i have used this program. i brought a clip in just to try the noise reduction, now my entire sound system sounds like it is echoing. all my video files, music files, etc. i did not save anything and am unable to undo whatever was done. how do i get my sound back to normal?

Close Audacity and reboot your computer and your sound system should return to normal.

Which version of Windows are you using?
