how do i reduce high speed dubbing to normal speed?

I have hearing tapes that were recorded using high speed dubbing. I have converted them to wav files. How do I slow them down to normal speed and pitch?

Import the WAV files into Audacity. They are probably at a sample rate of 44100 Hz. I assume that they play at twice normal speed.

In the Track Drop-down menu [ ] choose “Set Rate > 22050”.

You can now export the track as a WAV or MP3 for use in iTunes of other media players.

If the recording play at other than twice normal speed you will need to choose a different value in the “Set Rate” menu.
