Slow Playback

My recording is 8% slower than reality.
I noticed the lower frequency and found that a timed 60 seconds takes 65 seconds to play back.
Playback Speed is unchanged at 1.00x
I have made no other changes since last using it, when it appeared to be working correctly

Any thoughts?

Try changing the track “Rate” to 44100 (see: https://manual.audacityteam.org/man/audio_track_dropdown_menu.html)

If you need to change the track sample rate without affecting the pitch or speed, use “Tracks menu > Resample” (see: https://manual.audacityteam.org/man/tracks_menu.html)
