WAV files at intense speed

i am running windows 7 on my lap top and audacity 2.0. i had to reformat my computer. I backed up all my files, saved all my interviews on my external hard drive. they are saved and when i open them up Two appear on audacity screen, all of these are in wave format but they play at intense speeds, just an intense high pitch or low pitch depending on the length of the interview. i am new to this i was looking for a quick format to record and transcribe later. all help would be greatly appreciated thank you all.

Are you sure they are WAV format?
Where did these files come from? How did you record them?

WAV is a “container” format, so some WAV files especially those recorded by portable recorders may actually contain compressed audio formats.

To import those type of WAV files into Audacity you can try installing FFmpeg:
