Goldwave, audacity, Sound Forge, Etc. Most of the wave editors with time and pitch stretch pretty well. I recently did a file for a friend, that was tape recorded 35 years ago and the tape recorder was a tad slow, so the recording ran fast on new equipment. I adjusted the timing to the proper length and it sounded new again. It will work fine just don't save under the same name and you can go back.
