IF the audio was recorded to timecode sync then yes it will be at the 23xx fr. But if its just a wild recording then its hours mins secs and tenths / 100ths, not base 25 or base 24 etc etc.
if you play audio at the wrong speed youll hear it stright away.
what are you using to re unite the pics and audio. make sure the sample rate and bit depths ate correctly matched 1st. this will cause drift.
