I am using a Mac OSX 10.13.4 High Sierra with Audacity 2.2.2. Can anyone please tell me if it is possible to slow down the speed of a fast song for learning purposes without loosing its pitch?
Use the “Change Tempo” effect: http://manual.audacityteam.org/man/change_tempo.html
If you need to slow it down a lot, it may work best (and certainly quickest) with “high quality stretching” turned off (not selected), but test both to see which works best.
Great, thanks Steve. I will five it a try. Many thanks. Brian
