ValueError: could not convert string to float: '5.826450433232822e'

Hello @kahst, i am encountering an issue when running BirdNET on 2-hour WAV files, with a high overlap (2.9 seconds).

Here's my use case:

python analyze.py --i /scratch/vl1019/BirdVox-300h/BirdVox-300h_wav/2015-10-02_02-00-00_unit05.wav --o /scratch/vl1019/BirdVox-300h/BirdVox-300h_BirdNET --lat 42.38 --lon -76.49 --week 37 --overlap 2.9 --min_conf 0.01

and the traceback:

It looks like timestamps get encoded in scientific notation. Perhaps they are infinitesimally small due to the high overlap? If so, it would be good to raise an exception ahead of analysis.
