Sound of recording is thin and tinny

I am recording voiceovers and the audio sounds fine in the headphones, yet upon playback it sounds very tinny and thin. Almost like it is over compressed. I never had this issue before… Is there a way to reset the software in the event I hit something that I did not mean to?

Check the Audacity project-rate is set to what you want (>32000Hz for voice-over) …
