I am using Windows 7 and Audacity 2.1.0 . Is it possible to tone down or cut off sounds that are too high or sound tinny?
Try the Equalization effect: http://manual.audacityteam.org/o/man/equalization.html
or for a more simple effect, try “Bass and Treble”: http://manual.audacityteam.org/o/man/bass_and_treble.html
